17 Effect of the Insertion Devices A. Nadji, ESLSXVIII, Trieste, November

18 Energy Acceptance of the Bare Machine The energy acceptance of the bare machine is large : +/- 4%. Off-momentum FMA experiments have confirmed calculation results Calculations Measurements Durée de vie totale (h) VRF (MV) A. Nadji, ESLSXVIII, Trieste, November

19 Effect of the Insertion Devices Bare machine The measured energy acceptance is significantly reduced in the presence of IDs HU640 ID at maximum field in LV-mode HU640 ID at maximum field in LV-mode + 3 x U20 in-vacuum ID at minimum gap A. Nadji, ESLSXVIII, Trieste, November

20 A new optics to reduce the non linear effects of the 10m long HU640 undulator Nominal optics The horizontal β-function is reduced from 10 m to 5 m Injection HU640 New optics Injection HU640 A. Nadji, ESLSXVIII, Trieste, November

21 The tunes remain unchanged : The nominal horizontal emittance remains unchanged : 3.7 nm.rad The injection rate of the bare machine remains unchanged by scaling the kickers by a factor of 1.04 The beam lifetime is a little bit reduced for the bare machine but is improved in the presence of IDs Beam lifetime 400 ma (416 bunches) Nominal Optics New Optics Bare machine HU640 at maximum field in LV-mode HU640 at maximum field in LV-mode + 5 x U20 in-vacuum IDs at minimum gap 7 10 A. Nadji, ESLSXVIII, Trieste, November

22 Double mini-β z Optics Nanoscopium and Tomography : ~150 and ~200 m long beamlines will exploit high brilliance and coherence characteristics of the X-ray (5-25 kev) photon beam, both for diffraction limited focusing and for phase contrast imaging. Two canted in-vacuum undulators will be accommodated in a 12 m long straight section, with a 6.5 mrad separation angle. To provide low vertical beta functions at each undulator, an extra triplet of quadrupoles is added in the middle of the section. First operation with insertions planned for Autumn Double low beta optics Extra quadrupoles triplets In order to test the new machine optics, a triplet of quadrupoles has been installed temporary. A. Nadji, ESLSXVIII, Trieste, November

23 Experiment with Double mini-β z Optics The 4th symmetry of the machine is broken machine symmetry = 1 Measured Beam Lifetime at 400 ma multibunch mode Optics Working Point Beam lifetime (h) : Bare Machine Beam lifetime (h) : 5 in-vacuum at mini gap Present Simulation (Tracy): optics Modified 2 Modified 1 (different sextupole setting) Modified 2 (different sextupole setting) Working Point still under investigation as well as sextupoles tuning, from experience and simulations (BETA & Tracy & OPA codes) A. Nadji, ESLSXVIII, Trieste, November

24 Slow and Fast Orbit Feedback together Up to now with 2 different sets of correctors (Slow and Fast): Dead Band solution: SOFB and FOFB are efficient on different frequency ranges. No suppression of ID disturbances We have combined SOFB and FOFB Common frequency range. ID disturbances are well suppressed Interaction between SOFB and FOFB: Download of DC part in the fast correctors by the slow ones FOFB reference orbit is updated runtime by SOFB SOFB DC 10-2 D E A D B A N D 10-1 FOFB 1 10 Frequency (Hz) DC SOFB FOFB Frequency (Hz) 1 10 With two orbit feedback systems working together, machine stability benefits from: The slow system that provides good long term stabilization at all source points (also at bending magnets) The fast system that suppresses shorter term beam perturbations The use of a different set of fast correctors for fast corrections seems to be a good choice for: New machines: Requiring high frequency corrections (above 100 Hz) Requiring large kick strength with high resolution With Aluminum vacuum sections at strong corrector locations Older machines: That want to upgrade their orbit feedback system at a reasonable cost nicolas.hubert@synchrotron-soleil.fr A. Nadji, ESLSXVIII, Trieste, November

27 Mini-workshop (or brainstorming) on XBPMs SOLEIL, November 4th & 6th Two main issues prompted the workshop: 1. Dark current growth in one or two years of operation on XBPMs 2. Clear requirements for Instrumentation Technologies Libera photon Conclusions: 1. Dark currents: Analysis of black deposits shows metallic traces (Al, Fe,Ni, etc ) but the method is blind to carbon. The metals could be vaporised impurities in tungsten blades if high power photon beam accidentally hits a blade. It could also be the same process of carbon formation seen on SOLEIL beamline mirrors. An additional analysis sensitive to carbon will be performed. Solution: whatever the cause, the deposition speed must be slowed down with a chicane-like shield of the insulators. 2. Libera-Photon requirements. The requirements will be sent to IT by Nov. 30th 3. Common statement: Photon BPMs have a very good resolution, even better than electron BPMs. The workshop participants are going to share data in order to prove the XBPMs are reliable and can be used in orbit feedback systems. 4. Another workshop next year is proposed by SLS. It will address orbit feedback issues in addition to the XBPM ones. A. Nadji, ESLSXVIII, Trieste, November

32 Electron Bunch Length Measurement using the Incoherent Radiation Fluctuation Visible light diagnostic hutch Filling Pattern Monitor 3D translation Table Visible Light Monitor 50mm lens Oscilloscope 1GHz 900MHz APD Photodiode Streak camera 632.8nm Interferometer Filter Δλ = 1 nm Simple bunch length measurements can be achieved at low cost. The shorter the bunch, the more accurate it is. Already tested at the ALS in the 20 ps range (PRST 2009), it uses a fixed bandwidth and a turn by turn spectrum fluctuation of the visible range radiation from a dipole. Photon Beam Measurement using the visible light from a dipole has been done at SOLEIL for the nominal optics(10to40psrange)insingleandmultibunch modes. Better than 5% agreement with the streak camera has been found marie-agnes.tordeux@synchrotron-soleil.fr A. Nadji, ESLSXVIII, Trieste, November
