Is there an issue? Escalation Path

  • Issue concerns X-ray beam delivery: see here
  • Issue concerns ECS: see here
  • Spatial overlap of the optical lasers (drive and VISAR) with X-rays

    • Start by moving to the desired target (refer to the python manual here for details on the arguments)

      op.move_to_target(config="coliner", frame_cfg=[1, "F1", 1, "F2", 1, "F3"], frame=2, target="A2")

    • Continue by checking the alignment of the drive lasers

      • Set the system in a mode where the laser energy is minimum, the filter is removed from questar 1 and the trigger is enabled

        op.check_front_alignment()
      • Confirm you see a scattering signal close to the X-ray cross (342, 561)

      • Move the hexapod X axis to center the beams on the cross and produce a round scattering signal

        x.tg_x.umvr(50e-6)
    • Continue by checking the alignment of the VISAR system

      • Adjust the VISAR Z axis to make sure the image is round and sharp (could be set to the value by using the right equation as well)

        x.visar_z.umvr(50e-6)

      • Alternatively, move the Z value by exactly the hitckness of the ablator + material of interest and add the change in position due to the visar window. To calculate the change use the following command

        op.visar_window_compensation(material="LiF", thickness=400e-6)

  • Take a reference

    op.ref_only(
	xray_trans=0.2,
	xray_num=5,
	shutters=False,
	dark=0,
	daq_end=True,
	calibrant="",
	rate=1,
	visar=True,
	save=True,
	slow_cam=False
)

  • Take a shot

    op.optical_shot(
	shutter_close=[1, 2, 3, 4, 5, 6],
	lpl_ener=0.3,
	timing=5.0e-9
	xray_trans=1,
	xray_threshold=0.2,
	save=True,
	daq_end=True,
	auto_trig=True,
	auto_charge=True,
	visar=True,
	debug=False,
	ps_opt=True
)
  • Temporal overlap

    • go to Ti sample

      op.ti()
    • remove the Be CRL

    • open slit4 to 400 mic

      op.slit4.move(0.4)

    • set full X-ray transmission

      op.SiT(1)

    • open the pulse picker

      op.pp.open()
  • No labels
