PEARL Instrument Details

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.
