Welcome to the PLEIADES Wiki! Here you will find the documentation for construction records, maintaining, and operating the ILIMA heavy-ion pocket detectors for the ESR: the CsI–Silicon Particle detector for Heavy ions Orbiting in Storage rings (CsISiPHOS) and the ParticLE sIlicon-scintillAtor DEtector for Storage rings (PLEIADES).

Fully assembled PLEIADES detector mounted on flange arm.

Here are some quick links:

Operation:

• Detector structure: overview of detector and physics principles behind detector operation.
• Installation instructions: instructions on assembling detector, installing detector in ESR pocket, and cabling table for connecting flange to DAQ.
• DAQ operation: details on how to run the DAQ during an experiment, including online Go4 analysis.

DAQ Details:
