OSIRIS

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

Background & Timeline

OSIRIS is a long established instrument at ISIS, on TS1. The OSIRIS web page describes the background to the instrument. A schematic layout of OSIRIS is shown in ​this diagram.
OSIRIS shares a port with IRIS. We may need to have a way of sharing information between the IRIS and OSIRIS control systems. It might also be worth migrating IRIS and ​OSIRIS to IBEX at the same time.

Note: DAE

Main Detector banks + 2-3 monitors.

Note: Pfeiffer

Two controllers each with four active channels.

1. Model TPG 300

2. TPG300 support is implemented via #216 and #2063

Note: McLennan

1. Controls Rotating centre-stick, McLennan-Newport Rotation Stage

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

Note: Oxford Instruments

1. Dilution fridge: Triton.

   • See #2915

2. 7.5T Cryomagnet (aka the Teslatron)

   • See #2593

3. Variox Cryostat (OXF-08)

   • See #1389, #1390, #1391

Note: Eurotherm

Used to control temperature of top-loading CCRs, Furnace, Orange Cryostat devices. OSIRIS has 3 Eurotherm devices, arranged in a single crate, as illustrated in the photograph of the Eurotherm Crate.

Note: LakeShore

Three model 218 temperature controllers in total, each with 8 active channels. Two monitor the temperature of the Analyser and one the beryllium filter.

1. Model 218. The 3 LakeShore devices, are mounted in the OSIRIS rack.

Note: Neocera

1. Neocera LTC-21 Manual

2. See also #1828

Note: CryoValve Controller

1. Implemented on IRIS - see #1405. The CryoValve Controller sits on the OSIRIS rack.

OSIRIS Notes

Specialist Panels/Systems

OSIRIS has the following specialist panels/systems:

1. IRIS CryoValve

   • see CryoValve Controller note

Motion Control

OSIRIS has the following devices under motion control:

1. Jaws

   • 2-axis, North and South blades only. I.e. only vertical gap and centre can be controlled.

2. Beryllium Filter

   • single axis, “IN/OUT” device moving between two setpoints.

3. Sample Changer

   • N.B. For the avoidance of doubt: OSIRIS does not currently (September 2018) have a sample changer. There have been discussions about building one but, for the foreseeable future, there is no sample changer.
