EMMA Instrument Details
This page collects information that will be useful for the implementation of the IBEX control system on EMMA.
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.
EMMA will migrate from the SECI control system to the IBEX control system in summer 2017.
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).

Main Detector banks + fixed monitors. EMMA has 4 monitors:
- Monitor 1: stationary; located after the T0 chopper
- Monitor 2: stationary; located after the Fermi chopper
- Monitor 3: stationary; located between the jaws and the Y-Z table
- Monitor 4: currently stationary, but would like it to be moveable in future; located after the rotation stage
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:

EMMA has a single Fermi chopper (manufactured by SKF).

The Fermi chopper control crates (located in the EMMA rack) look like this:
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.
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.
The vacuum system (TPG300) on EMMA is currently (06/03/2017) not operational. Outside possibility that it may be operational by cycle 2017/02.
Driven by Galil controlled motors. See see Galil note.
In SECI, Y-Z Table has its own GUI. No particular reason for this; it could be merged with the Rotation Stage UI.

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

CAEN high-voltage system is a SYS2527 (see tickets: #212, #241, #320, #419, #424)
For the future - it's on the wish list (model not currently known).
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).
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.
For the future - it's on the wish list. Desired models are:
