WISH Notes

WISH has the following specialist panels/systems:

  1. Rotating CCR (PM600)
    • See C:\LabVIEW Modules\Rotating CCR\Rotating CCR - Front Panel.vi
  2. GEM Beamline Jaws (PM341)
    • check existing VI on WISH (GEM has been upgraded since original system was written)
    • PM341 is a McLennan model
    • Instrument scientist is not sure why GEM VIs are installed on WISH (they may not actually be used).
  3. GEM Jaws (Linmot)
    • check existing VI on WISH (GEM has been upgraded since original system was written)
    • Instrument scientist is not sure why GEM VIs are installed on WISH (they may not actually be used).
  4. GEM ORC
    • check existing VI on WISH (GEM has been upgraded since original system was written)
    • See also #2409 and #2808
    • WISH does have an ORC. Need to check if it the same as the GEM ORC.
  5. MAPS CCR (PM600)
    • See C:\LabVIEW Modules\Instruments\MAPS\MAPS CCR\MAPS CCR - Front Panel.vi
  6. PEARL Pressure Transducer
    • See C:\LabVIEW Modules\Instruments\PEARL\PEARL Pressure Transducer\PEARL Pressure Transducer.vi
  7. PEARL Pressure Cell Controller
    • See C:\LabVIEW Modules\Instruments\PEARL\PEARL Pressure Cell Controller\PEARL Pressure Cell Controller - Front Panel.vi
  8. POLARIS Sample Changer
    • See #2173
    • See also C:\LabVIEW Modules\Instruments\POLARIS\POLARIS Sample Changer\POLARIS SC - Front Panel.vi
  9. WISH Jaws
  10. WISH Lakeshore 370
  11. WISH Oscillating Radial Collimator (Galil) - see https://github.com/ISISComputingGroup/ibex_developers_manual/wiki/MERLIN,-LET-and-WISH-Oscillating-radial-collimators#wish-specifics for more info
  12. WISH Vacuum PLC

WISH has the following devices under motion control:

  1. jaws
  2. XYZ stage
    • This is also referred to as/is controlling the "Alignment Flange"

WISH also tends to borrow things from other instruments. Commonly used equipment:

  1. PEARL pressure controller
  2. Mercury-controlled Heliox cryostat insert
  3. Blue Cryostat (ITC controlled)
  4. IRIS Baratron Gas cell
  5. Automatic needle valve - see note on ticket #6695 for investigation, ticket #4240 for IOC implementation and ticket #6777 for OPI.

WISH SECI Configs

Document information about WISH SECI configs here.

Note: Most of WISH configs revolve around the WISH base config. This has been created as a component in IBEX and subsequent components for each thing that is added to the WISH base config should be added as components (i.e. the Teslatron, Strain Cell, Rotation stages etc.)
