- Prepare the hutch for the shift (done 1h before the actual start time)
- no gate valve in the trajectory
- check in the vacuum windows that no gate valves from the NEH to the MEC hutch are IN (red)
- it is ok that the DG2 STP 1 is IN
- it is ok that the GL window is IN in MEC
-
open the rolling status and confirm that no devices upstream the hutch obstructs the beamcheck that all devices in the beamline are in OUT position
Code Block language py theme RDark linenumbers true op.rs()
- insert yag3
- make sure all GREEN from 'Machine Protection' list
- check 'MR1L3' mirror OUT (-6000) position (after XCS)
- 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:
- close DG2 STP 1
- open mecpython and use op.rs()
- 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 : check coating for photon energy
- 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
