EMMA

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

Background & Timeline

EMMA is an instrument at ISIS, on TS1 and used primarily for test purposes. The primary users of EMMA are the sample environment team and the detector team. There appears to be no web pages (or other material) describing the background to the instrument.

Instrument scientist contact is Jeffrey Sykora.

Control System

EMMA will migrate from the SECI control system to the IBEX control system in summer 2017.

EMMA Equipment

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

The following items are on EMMA’s wish-list. They are items for the future (i.e. support is not required until such times as the individual items can be procured).

Manufacturer	Model	Type	Connection	Driver	Notes	Use in ISIS cycle
CAEN		Digitiser	Ethernet		see CAEN Digitiser note
Acqiris		Digitiser	RS-232		see Acqiris Digitiser note
NI		Digitiser	RS-232		see NI Digitiser note
Tektronix		Oscilloscope	Ethernet		see Tektronix note

Note: DAE

Main Detector banks + fixed monitors. EMMA has 4 monitors:

1. Monitor 1: stationary; located after the T0 chopper

2. Monitor 2: stationary; located after the Fermi chopper

3. Monitor 3: stationary; located between the jaws and the Y-Z table

4. Monitor 4: currently stationary, but would like it to be moveable in future; located after the rotation stage

Note: Choppers

One T0 chopper.
Chopper is ISIS Mk2 chopper. Mk2 choppers have a serial interface (not Ethernet like Mk3). See #2130 for IOC & OPI for Mk2 chopper.
The front panel of the Mk2 chopper control crate (located in the EMMA rack) looks like this:

• wide angle view

• zoomed-in view

Note: Fermi Chopper

EMMA has a single Fermi chopper (manufactured by SKF).
Link to Manual
The Fermi chopper control crates (located in the EMMA rack) look like this:

• Front View (upper & lower crates)

• Rear View (upper crate)

• Rear View (lower crate)

Note: Fermi Chopper Lift

The Fermi chopper is lifted into position by a Galil controlled motor.
The Fermi chopper must not be operated when it is not in the beam (i.e. in the parked/upper position) There is a hardware interlock to prevent the Fermi chopper from being operated in the parked position. This interlock is implemented in the Galil controller, via a Galil program (described in the EMMA chopper lifter - Handover document). In SECI a simple VI is used to provide a GUI, which passes parameters to the Galil program, so that the user can control the Fermi Chopper lift. IBEX should provide a similar capability via an IOC and OPI.

Note: Jaws

EMMA has one four-blade set of jaws. All blades driven by motors connected to Galil controllers. Jaw set is manufactured by Advanced Design Consultancy.

Note: Vacuum System

The vacuum system (TPG300) on EMMA is currently (06/03/2017) not operational. Outside possibility that it may be operational by cycle 2017/02.

Note: Y-Z Table

Driven by Galil controlled motors. In SECI, Y-Z Table has its own GUI. No particular reason for this; it could be merged with the Rotation Stage UI.

Note: Rotation Stage

Driven by Galil controlled motors. In SECI, Rotation Stage has its own GUI. No particular reason for this; it could be merged with the Y-Z Table UI.
Photograph of Rotation Stage. It sits on top of the Y-Z table when in use.

Note: CAEN HT

CAEN high-voltage system is a SYS2527 (see tickets: #212, #241, #320, #419, #424)

Note: CAEN Digitiser

For the future - it’s on the wish list (model not currently known).

Note: Acqiris Digitiser

For the future - it’s on the wish list. Desired model is Acqiris digitiser - PXI8570 controller chassis with DC 440 (400MS/s 100 MHz) digitiser card.
Note that Acqiris is now part of Keysight (see Keysight digitizers).

Note: NI Digitiser

For the future - it’s on the wish list. Desired model is National Instruments digitiser - PXIe-1082 chassis, PXIe-8135 controller and a PXIe-5162 digitizer (5GS/s and 1.5GHz). See NI Digitizers/Oscilloscopes.

Note: Tektronix

For the future - it’s on the wish list. Desired models are:

1. Tektronix Oscilloscope DPO7000

2. Tektronix Oscilloscope MSO4054
