This page collects information that will be useful for the implementation of the IBEX control system on PEARL.

Background & Timeline

PEARL is a powder diffraction instrument on TS1 at ISIS, dedicated to high-pressure studies. The PEARL web page describes the background to the instrument.

Control System

PEARL will migrate from the SECI control system to the IBEX control system.

PEARL Notes

PEARL has the following specialist panels:

  1. PEARL Alignment
    • see C:\LabVIEW Modules\Instruments\PEARL\PEARL Alignment
  2. PEARL Beam Dimensions

Compare with similar systems on GEM and POLARIS.

PEARL has the following devices under motion control:

  1. Jaws
    • see C:\LabVIEW Modules\Instruments\PEARL\PEARL Jaws\Screens
  2. Rotation stage
  3. XYZ stage

Compare with similar systems on GEM and POLARIS.

There are some inaccessible front end jaws on PEARL controlled by the Galil, these are not used but must be kept open for operation. They are homed to the forward limit and seem to typically be kept about 4/5mm inside that position for running. This should be kept in mind when migrating the Galil.

PEARL SECI Configs
