Beam synchronous DAQ with run_control

• Start run control:

  • /sf/jungfrau/bin/run_control, then chose pgroup

• Acquire pedestal
  • From “Expert” panel in run control
• Acquire data (single point scan)
  • “Run”
• Acquire scans
  • In “Scan” panel set motor positions
  • Check “Run scan”
  • “Run”
• Set bs and ca channels
  • Load files in “Configure” panel
• Set Jungfraus
  • In “Configure” panel check JF detectors

Jungfrau 1.5M

• Start high voltage after power has been given to the detector:
  • Power on in “Configure”
• Power off by disconnecting power cable
• 1Hz image stream
  • web browser with sf-daq-cristallina:5016

Jungfrau 8M

• Start by toggling “lever button” for ~1sec → no high voltage yet
• Start high voltage after power has been given to the detector:
  • Power on in “Configure”
• Stand by by toggling “lever button” for 1sec
• Power off by disconnecting power cable
• 1Hz image stream
  • web browser with sf-daq-cristallina:5017

Signal attenuated with 25 dB 3GHz attenuator

• Signal is on channel 0 of the scope on the Cristallina IFC1210
• Broadcasted to bread: waveform, signal-background, first computation output

pshell workbench:

• pshell_cr

  • Can be used for scans, not clear how it works
  • Jungfrau not accessible
• Scan:
  • Set positioners
  • Set detectors: screen_panel ROI, bread channel
  • See /sf/cristallina/config_pshell_cr/script/example.scan

Strip charts (pshell based):

• strip_chart, then load wished strip chart from /sf/cristallina/config/strip_chart

  • /sf/cristallina/config/strip_chart is read-only for gac-cristall

Correlation panel (pshell based):

• correlation panel

Bsread stream:

• bs receive …

• bs avail (...)

• bs config (?)

Set pointing:

A useful command is to switch between which slit is open or closed

caputq SARFE10-OAPU044:MOTOR_W 0.25; caputq SARFE10-OAPU044:MOTOR_H 0.25; caputq SARFE10-OAPU092:MOTOR_W 3.00; caputq SARFE10-OAPU092:MOTOR_H 3.00;

(to open the back slit and close the upstream one)

caputq SARFE10-OAPU044:MOTOR_W 3.00; caputq SARFE10-OAPU044:MOTOR_H 3.00; caputq SARFE10-OAPU092:MOTOR_W 0.25; caputq SARFE10-OAPU092:MOTOR_H 0.25;

(to do the opposite, open the front and close down the downstream slit)

To view the beam after both slits, use SAROP21-PPRM113 camera (from the screen_panel).
