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

Background & Timeline

CHRONUS is an instrument on the RIKEN-RAL Muon Facility at ISIS, on TS1. The CHRONUS web page describes the background to the instrument.

Control System

CHRONUS will migrate from the SECI control system to the IBEX control system in MMMMMMMM YYYY.

CHRONUS Equipment

The equipment listed below is used on CHRONUS. Please add new information (e.g. new items of equipment, new notes, information about drivers, etc. to this table).

Manufacturer Model Type Connection Driver Notes
ISIS DAE 2 Detector Electronics Ethernet see DAE note
ISIS ??? ISIS Vacuum System see Vacuum System note
Pfeiffer TPG300 Vacuum Gauge RS-232 EPICS see Vacuum System note
Kepco BIT 4886 I/F card GPIB, RS-232 see Kepco note
Oxford Instruments Triton Dilution Fridge RS-232 see Oxford Instruments note
Oxford Instruments Mercury Temperature Controller RS-232 see Oxford Instruments note
Oxford Instruments Cryogenic Equipment RS-232 see Oxford Instruments note
LakeShore 332 RS-232 EPICS see LakeShore note
Lakeshore 372 Temperature Controller see Lakeshore note
Cryomagnetics LM500 Liquid Cryogen Level Monitor RS-232 see Cryomagnetics note
Note: DAE

See multi-detector and single-detector below.

Note: McLennan

Support for McLennan devices is well established (see #1099 and #1100 and subsequent tickets.

Note: Jaws

Provide information about CHRONUS jaws.

Note: Vacuum System

TPG300 support is implemented via #216 and #2063

Note: Kepco
  1. Kepco BIT 4886 is an interface card for Kepco bi-polar (BOP) power supplies. The fact that there is a Kepco interface card tends to imply that there is a Kepco power supply in the list of equipment on CHRONUS (but it does not seem to have been listed).

Note: Eurotherm

Eurotherms are used to control temperature Orange Cryostat, CCR and Furnace devices.

Note: Lakeshore
  1. Model 332 temperature controller. Model 332 has now been superseded by Model 335.
  2. Model 372 temperature controller.
  3. On muon instruments, the Triton fridges have an additional Lakeshore controller (the 372) to allow control and continuous readout of the sample temperature (the OI software doesn’t allow this using the in-built Lakeshore, despite the unit having a dedicated channel for the sample thermometry).
  4. There are EPICS drivers for a variety of Lakeshore devices.
Note: Oxford Instruments
  1. Dilution fridge: models to be determined.
    • Triton LabVIEW Driver : C:\LabVIEW Modules\Drivers\Triton
    • Triton Documentation : C:\LabVIEW Modules\Drivers\Triton\Documentation
    • See also #2915
  2. Blue Cryostat: models to be determined.
Note: Cryomagnetics
  1. LM500 model appears to have been superseded by Model LM-510 Liquid Cryogen Monitor. Spec sheet for the LM500 is still available. See also spec sheets and manual on ICPDiscussions.

Obsolete CHRONUS Equipment & SECI Configs

The equipment listed below is referenced in SECI config files on CHRONUS . It is highly likely that the config files are no longer relevant (they are old, dating from 2011 or 2012), therefore, the references are to devices that are obsolete or simply not used on CHRONUS .
