Vacuum Thermal Insulation and Thermal Components RUAG Space is the leading European supplier of multi-layer insulation for spacecraft and market leader of superinsulation for cryogenic medical systems. The experience we have gained in more than two decades of thermal design and production enables us to increase your competitiveness with RUAG s leading edge technology solutions. Our vision is to be the leading competence centre for vacuum thermal insulation solutions for space and industrial applications. Our mission is the development and production of multi-layer insulation for space and cryogenic industry to make our customers more competitive. To achieve this mission we focus on first-class products and reliable and long-standing partnerships with our customers. RUAG Space activities for development and production of multi-layer insulation for space applications (satellites and instruments) have started in 1991. Since then we have developed our competencies and skills in more than 50 projects to become the leading European supplier of multi-layer insulation for spacecraft. Moreover, RUAG Space has developed great expertise in the field of cryogenic insulation. Today RUAG also offers the development and the production of cryogenic superinsulation for various applications such as Helium liquefiers or superconducting magnets. Our development and production process comprises: Thermal and Mechanical Engineering Design and Development Production and Integration Our value creating chain includes the following tasks: Selection of the insulation composition with attachment and grounding CAD Design (3-D and 2-D) Prototyping, support during first installation Production (standard and taylor-made products and also build to print) Delivery logistics ISO 9001 / ISO 14001 RUAG Space GmbH is certified to ISO 9001, ISO 14001 and EN 9100 by DNV. Restriction We have taken care to collect and present technical and performance data which are based on supplier data, own measurements and tests. These data are meant to help our customers in their design process and support the selection of the best insulation type for the application. However, these data are indicative only and have to be proven by specific measurements in the relevant environment. Build to print: We can produce superinsulation to customer drawings. We accept the definition of blanket shapes in DXF, IGES or STEP format. RUAG Space Thermal Insulation Products 3

Cryogenic Insulation (Coolcat Line) Our product family Coolcat comprises standard insulation and tailor made insulation. Our insulation is composed of aluminized polyester foils interleaved with polyester spacer materials or is made of aluminium foils interleaved with glass spacer materials. In addition, we supply welding protection materials, tapes, sensors Laser Cutting: Polyester superinsulation blankets are cut to shape using our numerically controlled (NC) cutting machines. Polyester superinsulation is laser cut whereas aluminium/glass insulation is cold cut. The laser cutting process assembles the multi-layered package around its cutting edges. The edges are held together by bridges of molten polyester. However, laser cut edges are open for edge pumping (see picture). No significant difference in thermal performance was found in comparative calorimeter testing between multi-layer insulation with cold cut and laser cut edges: Laser cutting does not increase edge effects! We can NC laser cut to a maximum width of 2.7 m. The length of the cutting area is 3.0 m, which does not limit the length of individual superinsulation blankets, as the superinsulation is fed into the cutting machine on a conveyor, forwarding the band when needed. This method of producing polyester superinsulation has proven to be very efficient, because no additional assembly of the layers (pins, staples, welding points or similar) are required to attain a robust blanket with very good handling properties. The thermal performance is optimized by minimizing thermal shortcuts through assembly elements. When compared to cold cut blankets, where cracks could start from the edge of each single reflector foil, laser cut/welded blankets combine the strength of several thin layers and thus offer a much higher tear strength. No crack stopper holes are needed at the end of laser cuts or inside corners (<180 ). During the evacuation of the vacuum space, the air and outgassing products enclosed within the multi-layer package of the insulation can be pumped at the open edges (edge pumping) and through perforation holes of the reflector foils (broadside pumping). Most of our Coolcat superinsulation is made of perforated foils to allow broadside pumping. Thus the insulation gap can be evacuated more quickly and the residual vacuum pressures are lower than for edge pumping only. We supply standard sheets and rolls of polyester superinsulation such as Coolcat 1, Coolcat 2 and Coolcat 2 NW. These standard superinsulation products are held together by a grid of ultrasonic spot welding points. The standard pitch of these welds is 0.3 x 0.3 m. These welds assemble the multi-layer package and ensure that the multi-layered package will not fall apart when our customers cut their own shapes using scissors, scalpels or similar.

Coolcat BR-50 tape is recommended for closing superinsulation blanket joints. Depending on the configuration of the cryostat it may be possible to completely enclose the cold parts to be insulated with a shell of insulation blankets. In this case the taping of superinsulation joints may be sufficient to hold the insulation in place. In other cases it may be necessary to use additional fixation elements such as plastic pins. Superinsulation types such as Coolcat 2 NF, Coolcat 2 LOX and Coolcat H, which are not made of polyester but contain other materials such as aluminium foil or glass-fibre fleece are cold cut on our NC cutting machines using oscillating knives. This process does not assemble the multi-layer package and so we use tag pins to hold the blanket together. We offer NC cold cutting up to a blanket size of 3.0 x 0.95 m. We cold cut larger blankets by hand if required. The superior performance of Coolcat insulation is based on: High quality polyester film, 6 or 12 µm thick, double side aluminized at minimum 40 nm (400 Angstrom). Reflector foils are separated with pure polyester spacer material. 10 layers of foil and 10 layers of spacer are combined as a semi finished insulation lay-up, ready for cutting. The insulation is perforated for perfect evacuation of the vacuum chamber. RUAG Space thermal insulation is designed based on CAD models and is cut accurately on the numerically controlled laser cutting machine. The insulation is easy to handle due to the laser cut edges. The insulation performance is long term stable, no degradation of insulation due to the spacer material, no flattening, limited gravitational compression, no severe compression effect over edges. The reproducability of performance in a serial production is very high, only very small deviation is measured. RUAG Space Thermal Insulation Products 5

Coolcat 1 Coolcat 1 is a crinkled superinsulation composed of 10 layers of polyester foil, single-side aluminized and crinkled. Coolcat 1 offers a high thermal performance, especially between liquid nitrogen and liquid helium temperature levels. The crinkled polyester foil which is used in Coolcat 1 has been used in high performance cryogenic insulation for more than 50 years. The crinkling ensures only minimum contact areas between the reflector foils, which minimizes heat conduction. Crinkled superinsulation must be applied with extra care to avoid compression and thermal shortcuts between the foils, especially at corners. For the supercrinkled version of Coolcat 1 the reflector foil is processed to provide a more intense crinkling. Standard sheets are assembled by ultrasonic spotwelding points at a grid of 200 x 200 mm. For a good thermal performance compression of the superinsulation must be absolutely avoided. It is recommended to allow a minimum insulation gap thickness of 3 mm per 10 layers and to install the insulation in a loose way. All polyester reflector foils are aluminized to provide a specific surface resistance of 1.5 3.0 ohms per square (coating thickness > 25 nm). The low coating thickness minimizes edge effects caused by heat conduction within the coating, which is most important at liquid helium temperature level. Coolcat 1 is not perforated.

Coolcat 2 Coolcat 2 is a spacered superinsulation composed of 10 layers of polyester foil, double-side aluminized, perforated and interleaved with 10 layers of knit-woven polyester spacer material. Coolcat 2 offers a high thermal performance. For many years Coolcat 2 has been widely used by the research community for the insulation of cryogenic equipment at a laboratory scale. Spacered superinsulation offers more robust thermal performance than crinkled superinsulation (for example at corners and under compression). Knit-woven spacers are more light-weight and slightly thinner than the non-woven spacers, which are used in Coolcat 2 NW. Knit-woven spacers are dimensionally less stable than non-woven spacers. In comparison with Coolcat 2 NW, handling and installation of Coolcat 2 insulation is more difficult. Coolcat 2 has a nominal compressed thickness of 1.0 mm per 10 layers. For a good thermal performance compression of the superinsulation should be avoided. It is recommended to allow a minimum insulation gap thickness of 3 mm per 10 layers and to install the insulation in a loose way. All polyester reflector foils are aluminized to provide a specific surface resistance of < 0.8 ohms per square (coating thickness > 40 nm). For low outgassing Coolcat 2 contains 100% polyester spacer, which has been washed and thermo-fixed at high temperature to minimize outgassing. For short pumping times all double aluminized polyester foils are perforated at an open area of 0.05 to 0.1 per cent. Maximum baking temperature: 423 K.

Coolcat 2 NW Coolcat 2 NW is a spacered superinsulation composed of 10 layers of polyester foil, double-side aluminized, perforated and interleaved with 10 layers of non-woven polyester spacer material. Due to its high thermal performance and good handling properties it is used in serial production of MRI and NMR cryostats at an industrial scale. Spacered superinsulation offers more robust thermal performance than crinkled superinsulation (for example at corners and under compression). Non-woven spacers are dimensionally stable and therefore Coolcat 2 NW offers easier handling and more efficient installation than Coolcat 2 (knit-woven spacer). Coolcat 2 NW has a nominal compressed thickness of 1.4 mm per 10 layers. For a good thermal performance compression of the superinsulation should be avoided. It is recommended to allow a minimum insulation gap thickness of 3 mm per 10 layers and to install the insulation in a loose way. All polyester reflector foils are aluminized to provide a specific surface resistance of < 0.8 ohms per square (coating thickness > 40 nm). For low outgassing Coolcat 2 NW contains 100 % polyester spacer without binder. For short pumping times all double aluminized polyester foils are perforated at an open area of 0.05 to 0.1 per cent.

Coolcat 2 NF Coolcat 2 NF is a spacered superinsulation composed of 11 layers of glass fibre fleece spacer interleaved with 10 layers of pure aluminium foil. Coolcat 2 NF is high temperature tolerant and non flammable. It has been tested to be self-extinguishing in 100 per cent gaseous oxygen environment. It has been used for the thermal insulation of automotive cryogenic hydrogen storage tanks. The glass fibre spacer has a binder content of 8 per cent and therefore the insulation is not liquid oxygen compatible in accordance with ASTM D2512-95. Coolcat 2 NF sheets are held together by nylon tag pins along their short ends at a pitch of 0.2 m. Coolcat 2 NF has a nominal compressed thickness of 5.0 mm per 10 layers. For a good thermal performance compression of the superinsulation should be avoided. It is recommended to allow a minimum insulation gap thickness of 7 mm per 10 layers and to install the insulation in a loose way. Maximum baking temperature: 523 K.

Coolcat 4K Coolcat 4K is a low absorptance helium can laminate. It is a laminate of a 6 µm pure aluminium foil and a 12 µm polyester foil, double-side aluminized. Coolcat 4K laminate combines the very low absorptance of a pure aluminium foil with the good handling properties of a polyester foil. As a superconducting magnet thermal insulation the small aluminium foil thickness offers lower heat dissipation at 4 K (incurred by Eddy currents) and lower Lorentz forces at quench. Coolcat 4K does not crinkle and tear the way aluminium foils do. It has the higher tear resistance of a laminate. This makes the installation of the insulation easier and saves labour cost. Coolcat 4K is available at a maximum width of 1.830 m. We offer customized Coolcat 4K sheets to a maximum width of 1.750 m. These sheets are cut to customer specification using our cost efficient automated NC laser-cutting machine. Installation: The mat side of the foil is the aluminium foil side and shall be used for thermal insulation. The shiny side is the aluminized polyester side and shall face the cold surface. An adhesive transfer film can be applied to the aluminium coating of the shiny side of the laminate for its attachment to the cold helium vessel surface.

Coolcat H Coolcat H is a welding protection made of aluminium foil and fiberglass cloth. It is recommended for the protection of polyester superinsulation against welding heat. This welding protection is needed because polyester superinsulation is flammable and melts at 250 degree Celsius (523 K). Coolcat H insulates by reflecting the welding heat at its aluminium surface and by featuring the low conductivity of fiber-glass cloth in air under ambient pressure. The maximum service temperature of the E-Glass cloth is at 500 degree Celsius (773 K). The adhesive of the laminate fails above 150 degree Celsius (423 K). Welding trials are recommended to confirm if one layer of Coolcat H is sufficient for the customer application. The glass fibres have a diameter of larger than 6 µm and are not respirable. Coolcat H is available in rolls of 150 mm wide and 50 m long. We offer customized Coolcat H sheets to a maximum width of 1 m. These sheets are cut to customer specification using our cost efficient automated NC cutting machine. Article no.

Coolcat B-R50 Coolcat B-R50 is a low emissivity adhesive tape optimized for use under cryogenic environment. It is composed of a 25 µm polyester foil carrier, double-side aluminized and a high purity pressure sensitive acrylic adhesive. Coolcat B-R50 cryogenic adhesive tape has been developed specifically for thermal insulation in cryogenic applications, to provide lowest infrared emittance on its outer surface. This tape has been developed to replace tapes, which have a shiny appearance, but are second surface mirrors only. It is most recommended for the closing of superinsulation joints. Bonding strength at room temperature: Peel strength: min. 30 N / inch width (AFERA 4001) Shear strength: min. 70 N / 625 mm² The specified bonding strength is achieved within 10 minutes after application and will increase by 30 per cent after 24 hours; zero peel strength at 230 K. The tape meets the standard outgassing requirements for satellites of the European Space Agency. The adhesive of the tape is protected by a release liner. We offer tape dispensers, which automatically wind up the release liner. The tape is available 25 mm (1 inch) or 50 mm (2 inches) wide. It is delivered on cardboard core.
