Excel spreadsheet for the FEL settings is here.
- Prepare the hutch for the shift
- no gate valve in the trajectory!!!
- check that all devices in the beamline are in OUT position
- insert yag3
- no gate valve in the trajectory!!!
- 15 min before the shift begins, call ACR at x2151 to check:
- photon energy
- nominal pulse energy
- nominal pulse duration
- beam mode
- multiplexing
- e-loss scan needed?
- when you are beam owner (confirm with ACR), you can start the following:
- insert YAG0 ([1] op.yag0.insert())
- confirm FEL beam is on scale "0"
- confirm the shape of the beam is round
- insert YAG1 ([1] op.yag1.insert())
- insert MR1L4
- confirm on yag0 that the beam is properly deflected on the scale "8 cm"
- remove YAG0
- remove all Si attenuators ([1] op.SiT(1))
- open the pulse picker ([1] op.pulse_picker("open"))
- fine tune the pitch of MR1L4 to center the beam on YAG1
- insert YAG3 ([1] op.yag3.insert())
- remove YAG1
- fine tune the pitch of MR1L4 to center the beam on YAG3
- once they are done tunning
