TOSCA Instrument Details

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

Background & Timeline

TOSCA is an indirect geometry spectrometer, on TS1. The TOSCA web page describes the background to the instrument.

Control System

TOSCA will migrate from the SECI control system to the IBEX control system in late October 2018 (prior to Cycle 2018/03).

TOSCA Equipment

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

Note: DAE

See multi-detector and single-detector below.

Note: ISIS Mk3 Choppers

TOSCA has an ISIS Mk3 double-disk chopper.

Note: McLennan

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

As of 2018-11-15, TOSCA uses only one McLennan motor, which is for the sample changer. The other motors were used for a rotating centre stick and for a rotating stage - both of these were used once a long time ago. The McLennan which drove the rotating centre stick was configured during the migration and then removed after migrating as the scientists do not use it. If it is needed in the future, look at the standard configuration before 2018-11-14 to see details of the motor configuration for the rotating centre stick.

Note: Sample Positioner

The Sample Positioner is driven by a McLennan motor (i.e. it raises/lowers sample plates attached to a chain drive, driven by the McLennan). Here are 3 photograph of the Sample Positioner: One, Two, Three.

Note: Jaws

There are no jaws on TOSCA.

Note: Vacuum System

TPG300 support is implemented via #216 and #2063. The vacuum system is currently operated separately.

Note: Eurotherm

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

Note: LakeShore

TOSCA uses four Lakeshore 218s - not all of the channels are enabled on each of these.

1. Model 218
   • See also #1097, #1098 & #3223.

There are EPICS drivers for a variety of Lakeshore temperature controllers.

Note: Helium Gauge

1. The Helium Gauge is no longer used on TOSCA.

TOSCA Notes

TOSCA has the following specialist panels/systems:

1. MAPS CCR (PM600)
   • See McLennan note.
2. TOSCA Helium Level Gauge
   • See Helium Gauge note
3. TOSCA New Sample Changer (PM600)
4. Rotating Centre Stick (PM600)
   • See McLennan note.

TOSCA has the following devices under motion control:

1. XY beam scanner (2 axis GALIL motor - this GALIL moves about and is not permanently on TOSCA).
