ALBA Project Document No: Page: 5 of 21 1. Previous considerations 1.1 Objective a. The radiation monitor measurement system controls that the limit of the radiation dose levels given by the Spanish regulation [1] are followed, and the data obtained from it is used as document for the inspection local authorities. The network measurement system has to consist of photon (X and γ rays), neutron measurement stations and both, and a PC Central Control unit. Depending on the measurement site one X and γ rays monitor and one neutron monitor, jointly with one electronic system of local measurement (Local Control and Display Unit) will be mounted together. In other places the two types of detector will be installed separately (photons or neutrons), but all of them will be connected to the PC Central Control unit in any case (see Annex III and IV). b. During the commissioning of the ALBA accelerators, radiation portable detectors (either for photons or neutrons) will be used to check any shielding leakage. c. In addition, to determine what kind of element activation may occurs across ALBA, portable gamma spectrometers will be needed. d. In this report, a proposed network distribution for the photons and neutrons radiation monitors (also portable detectors and spectrometers) is given for all the ALBA facility (from the LINAC accelerator to the beamlines). Any other solution that will fulfil the technical specifications and the legal aspects is acceptable for CELLS, especially if some cost reduction applies. e. The scope of supply is divided into FOUR lots, as detailed in section 2. f. Due to the installation requirements and schedule, the delivery of the radiation monitors (for each of the four lots) has to be done in 2 batches. The first one shall be ready for the LINAC installation and the second one for the other 2 accelerators and beamlines (see the schedule in Annex I). Each batch delivery includes some portable detector units and spectrometers, as detailed in Table 2 (section 3.10). 1.2 ALBA description a. The ALBA synchrotron light source layout consists on 3 accelerators and 7 experimental beamlines (see Annex II). The acceleration system is formed by the LINAC injector, one synchrotron accelerator injector (called Booster) and finally the 2 nd synchrotron accelerator that stores the electron beam for several hours (the so called Storage Ring). The LINAC accelerates the electron current up to 100 MeV, then the current is injected at the Booster to be ramped up to 3 GeV, which is the nominal energy in the Storage Ring. Afterwards, passing by the Booster to storage flight path, the electrons are injected at the synchrotron Storage Ring, where the electron beam current is stored for a period of time of several hours. The length of the LINAC, Booster and Storage Ring are 15 m, 265 m and 285 m respectively. b. The overall charge delivered by the LINAC is 4 nc (per shot), and the maximum electron beam current stored (and consequently ramped) in the Booster is 10 ma, and at the storage up to 400 ma. All the acceleration and ramp process is based in 5 Hz repetition rate given by the LINAC (it could be tuned from 1 to 5 Hz). The stored beam (at the Storage Ring) is achieved after 5 minutes after the injection process has started (this time depends on the injection efficiency). The stored beam is circulating inside an ultra high vacuum system. In the bending regions (bending magnets or insertion device zones) the ultra relativistic electron radiates synchrotron radiation. The amount of stored electrons is reducing slowly due to the collisions with the residual gas and the electrons from the same bunch. For that reason after several minutes (depending on beam lifetime and the variation current accepted in the Storage Ring), it is needed to repeat the injection process (if the accelerator works on the so called top-up mode). c. To store the beam in the Storage Ring 32 dipole electromagnets (bending magnets) are used, with magnetic fields around 1.42 T, and 6 RF cavities where a transmission of high frequency of 500 MHz and 150 kw of power each is delivered to the electron beam. In the Experimental Hall it is planned to install 7 photon beamlines, with their corresponding measurement and control electronic system of high sensitivity. d. The LINAC accelerator is located in a separated vault next to the circular tunnel where the other 2 synchrotron accelerators are installed. The surface of the LINAC vault is 85 m 2 (22.5 m x 3.8 m) approximately. The walls are made of high density concrete (3.4 g/cm 3 ) of 1 m thickness, and the roof (3 m high) if formed by 2 layers of 0.5 m thickness made of normal concrete (2.4 g/cm 3 ). See Annex II for a detailed drawing.

ALBA Project Document No: Page: 6 of 21 e. The Booster and the Storage Ring are located in the same concrete tunnel. The inner wall has circular shape, while the outer one has a ratchet configuration (see Annex II). As in the LINAC, the roof is 3 m high formed by 2 layers of 0.5 m normal concrete, but in the Booster to Storage Ring transfer line area one more layer is added (total 1.5 m). The concrete inner wall thickness varies from 1 to 1.75 m depending on the accelerator position. It is thicker in the forementioned transfer line zone. The ratchet wall thickness is 1 m (normal concrete) for all the side walls and 1.5 m (heavy concrete) for all the front walls. The area contained inside this wall is a Prohibited Zone when the Storage Ring or the Booster are switched on. The Experimental Hall outside the wall is a Free Access zone (Dose Limit 1 msv/y). f. There are 3 different sources of radiation: gas and solid bremsstrahlung (also called prompt radiation) and synchrotron radiation. The gas and solid bremsstrahlung are produced in all 3 accelerators when the electrons from the beam hit the molecules and atoms of the residual gas or the vacuum pipe walls, the emitted radiation is in the X and γ ray energy range depending on the electron beam energy. The synchrotron radiation is produced when the electron current trajectory is bent either in the Booster or in the Storage Ring. This occurs in the dipole magnets (for both synchrotron machines) and in the Insertion Devices (ID) which are located in the Storage Ring straight sections. The photon energy of this radiation depends on the dipole and ID magnetic field strength (most of them are in the X ray region). Due to all these processes photons (X and γ) and neutron radiation are generated, and they have to be properly dealt with. g. In the beamline areas the main sources of radiation are gas bremsstrahlung and synchrotron radiation. However neutrons rising from the photon-nucleus reaction can be present too. For that reason a radiation monitor has to be placed next to the beamline wall (hutch beamline wall). h. The low energy synchrotron radiation, corresponding to the X ray range, is absorbed by the vacuum chamber walls (made of stainless steel). The purpose of the radiation monitor network object of the present specification is having a record from the γ and neutron radiation that are produced in any part of the installation, as well as providing interlock signals to the Personal Safety System (PSS), see Annex III. The intensity of the γ radiation spectrum has a maximum around 1 MeV, with a continuous extension up to the electron beam energy (around 3 GeV). The neutron radiation is formed by high resonance neutrons, with an energy spectrum similar to the spectrum from Cf, with a maximum located at 1 MeV; and with fast neutrons having energies that may reach 100 MeV. During the injection time, the radiation produced is pulsed, the time structure being around 100-600 ns pulse length, with a maximum repetition rate of 5 Hz, given by the LINAC time structure. Once the electron beam is stored, the electron current is formed by 445 bunches of 2 ns time length and 0.9 ma current each. The pulse characteristics in the ALBA accelerators are summarized in the table below: Radiation Source Pulse length Repetition rate LINAC 2 600 ns 1 5 Hz Booster 2 600 ns 1 5 Hz Storage Ring 2 ns (continuous) 500 MHz (continuous) Table 1. The pulse structure characteristic for the ALBA accelerator i. This radiation shall be measured in all the installation areas where the dose rate could be higher than the radiation background level. It applies out of the prohibited areas that are shielded. The area outside the LINAC vault and tunnel walls are zones under control. The objective of the network measurement system is to monitor the radiation at any time and to give the integrated dose for long period (see Annex IV). It is requested to compute the annual dose for the reporting to the national authorities. j. During injection a typical dose rate of 2.5 µsv/h, for neutrons and γ rays, can be expected. This implies an instantaneous peak value of 5.0 Sv/h (due to the radiation pulsed structure). k. The highest dose rate will happen during injection where the electron loss rate will be higher for the 3 accelerators, and next to the first optical element at the beamline. Depending on the vacuum pressure the gas bremsstrahlung dominates in the beamline, and it is related with the vacuum conditions. l. Between the injection steps the radiation does not have a pulsed structure (it comes from a stochastic electron loss), and the expected dose rate is in the range of the natural radiation background (0.1 µsv/h).
