  • ./newusers-4b.sh 2022-3 sarker-0000-a ( this will create file both in id4b and id4baux )
  • copy HRDMscans.mac to the specific folder

  • Change the HDRMscans.mac file with _samplename and _sampledirectory

Open the camera inside the front hutch

  • Open an terminal
  • type vimba
  • Vimba viewer will open with two cameras ( IP addresses: 1st crystal: 192.168.180.102, 2nd crystal : 192.168.180.101)

Open ion chambers

  • Open an terminal
  • type show_apms 0
  • type show_apms 1
  • type show_apms 2

for FOURC opening

  • Open an terminal
  • type fourc
  • press yes if fourc ask questions to change motor values

STEP 1: If you lost fourc/SPEC terminal

  • Open terminal
  • type findspec (it will provide all the spec information)
  • Check the getPid number
  • type fg <getPid number> (example # fg 21192)
STEP 2: Talk to beamline scientist

If you doesn't find anythng after STEP 1 fourc/SPEC terminal * If you not find the SPEC terminal, then type below command * kill -9 <getPid number> (example# kill -9 21192) * Open a new terminal * Type ‘fourc’

If you fourc/SPEC doesn't work
  • Open terminal
  • type quit
  • type fourc
If SPEC window is lost
  • Open an terminal
  • type findspec
  • If it is hidding, then type fg <PID number>

Step I: * Cover the detector * Before energy change (> 30 keV higher to lower < 18 keV) verify counts in ic1, ic2 and diode (getE : provide you the energy) Put mostab to 5 V Optimize counts (tweakup) syncE * Then try move energy and optimize mostab: moveE 11 matchUE 3 tweakup lup montrav * Open shuttur os1 4 4 * move the whole table up tw tabzu tabx tabzui 1 1 1

Detector setup

REXS

Setup :

mv pil6mx 100 mv pil6my 760

  • mv pil6mx 100 - move pilatus 6M to 100 mm x direction
  • mv pil6my 760 - move pilatus 6M to 760 mm y direction

To take the detecotor all the way end of the hutch

mv pil6mx 233 mv pil6my 885

  • mv pil6mx 233 - move pilatus 6M to 233 mm x direction
  • mv pil6my 885 - move pilatus 6M to 885 mm y direction
