LCLS LTU/Undulator/FEL Commissioning Goals Sep. 29, 2008
The third phase of LCLS commissioning (LTU/Undulator/FEL) will begin in November 2008, from gun through the final electron dump after the FEL undulator. The goals of this Phase-III commissioning cycle are outlined in the points below:
1) Full linac operations (drive-laser, gun, injector, BC1, BC2, and main linac) will be re-established to the 52-SL2 stopper in the BSY during the first 1 month of Phase-III commissioning (see previous injector and BC2/Linac goals).
2) The electron bunch will be transported to the main electron beam dump, through the FEL undulator, at up to 13.6 GeV with at least 200 pC of charge and minimal beam loss at a repetition rate of at least 10 Hz.
3) All relevant new electron beamline components (magnets, BPMs, screens, toroids, wire-scanners, RF-structures, dumps) will be operationally verified (with beam) in terms of polarity, calibration, function, timing, reasonable alignment, and motion-control, where relevant. Basic control system functionality will be validated simultaneously and as a consequence of this verification process.
4) All relevant new FEE photon beamline components (mirrors, imagers, collimators, attenuators, gas-detectors, thermal sensor, etc) will be operationally verified (with x-rays) in terms of polarity, calibration, function, timing, reasonable alignment, and motion-control, where relevant. Basic control system functionality will be validated simultaneously and as a consequence of this verification process
5) All machine protection (MPS) and beam containment systems (BCS) will be operationally verified early in the commissioning cycle to ensure safe operation for both personnel and hardware. PPS checkout is not part of commissioning.
6) The electron bunch will be characterized, and tuning sensitivities demonstrated, with regard to energy, energy spread, trajectory, charge, emittance, beta function, bunch length, and centroid coordinate stability in all six dimensions.
7) The undulator beam-based alignment (BBA) procedure has been successfully performed with the undulator segments all rolled in and all rolled out.
8) The undulator x-ray radiation will also be characterized, and tuning sensitivities demonstrated, with regard to wavelength, bandwidth, pointing, x-ray power, transverse size, and centroid coordinate stability in five dimensions (x-ray timing diagnostics will not be available at this time).
9) An x-ray flux of at least 106 photons/mm2 per pulse in a 0.1% bandwidth at 8 keV will be measured in the FEE.
