IRIS Instrument Details
This page collects information that will be useful for the implementation of the new control system on IRIS.
IRIS is a long established instrument at ISIS, on TS1. The IRIS web page describes the background to the instrument. A schematic layout of IRIS is shown in this diagram.
IRIS shares a port with OSIRIS. 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.
IRIS will migrate from the SECI control system to the IBEX control system.
The equipment listed below is used on IRIS. Please add new information (e.g. new items of equipment, new notes, information about drivers, etc. to this table).

Main Detector banks + 2-3 monitors.
- One McLennan will eventually be used to control the rotating centre-stick, McLennan-Newport Rotation Stage
- One McLennan is used to control the Sample Changer, currently set on port 1
- One McLennan has been used to control a stretching rig, currently set on port 2
The homing behaviour for the McLennans is currently under review. The McLennan IOC startup scripts have been partially customised for Iris based on observed behaviour for each device. This behaviour is subject to review by the development team.
The Sample Changer is driven by the McLennan motor (i.e. it raises/lowers sample cans attached to the sample changer). There is a photograph of the Sample Changer, which shows the sample cans attached to the bottom of the sample changer. There is also a diagram showing the dimensions of the Sample Changer (the diagram is taken from the instrument scientist's notebook - it is a sketch, not an engineering drawing (just to set your expectations :-) ).

CCR-11. Not directly computer-controlled - controlled via Eurotherm.
CCR-64. Not directly computer-controlled - controlled via Eurotherm.
Orange Cryostat: models to be determined. Eurotherm controlled.
Used to control temperature of top-loading CCRs, Be Filter, Furnace, Orange Cryostat devices. There are at least 6 Eurotherm devices on IRIS, arranged in two crates of 3, as illustrated in the photograph of the Eurotherm Crate.
- Model 218: Monitors temperature of Analyser Banks
- Model 336:
- Model 340: this model is now obsolete, having been replaced by the 336 and 350 models.
There are EPICS drivers for a variety of Lakeshore temperature controllers.
The Lakeshore 336 on IRIS is shown in the linked photograph.
Documentation on the Lakeshore 336 IOC setup can be found here.
Controlled via Eurotherm.
The MKS PDR2000A provides power and readout up to two (2) Baratron® pressure transducers.
There are EPICS drivers for a variety of MKS devices (although there is a driver for a PDR4000 pressure transducer, there does not appear to be one for a PDR2000).
Consists of ACM1000 Gauge controller, ACT200H Pump Controller, Neocera LTC-21 Temperature Controller

Due to be superseded by the Exchange Gas Controller.
Over the years, IRIS has built up a significant collection of SECI configs. Not all of them are current (some may no longer be used, or used only infrequently). We will need to investigate how to convert them to IBEX configs. The current list of IRIS configs is listed on trac.
The config files are located in the folder SECI\Configurations\ on the control server and have the extension .conf. Sub-configuration files have the extension .comp (component). The files with numbers as extensions (.1, .2, .3,etc.) are backups of the configuration and sub-configuration files.
Similarly, IRIS has built up a significant collection of genie scripts over the years. Again, many scripts are old and may no longer be used regularly. Most runs on IRIS are controlled via scripts. There will be a need to convert some of these scripts to genie-python, but probably not all.
The current list of IRIS genie scripts is listed on trac.
