Strategy & Tasks
• Strategy should take account of the need to– Have stand alone systems– Avoid duplication– Avoid dependence on DAQ for last minute commissioning
• Immediate Tasks:– Beam Line Controls:
• SC Solenoid• Cryogenic System• Interlocks• Conventional magnet power supplies• Diagnostics

The Survey
Controls, Instrumentation and Data Acquisition Survey• A focus of the Berkeley Collaboration meeting will be the control and physics parameters needed by MICE to fully qualify
and understand the measurements to the advertised precision. These parameters can cover any aspect of MICE from the ISIS beam, through the detectors, cooling channel down to the final calorimeter, interlocks, and any ambient or dynamic parameter (fast or slow). To facilitate this discussion you are kindly requested to complete this survey. The survey asks four questions:
1. PHYSICS PARAMETERS: Which parameters might it be important to include in the data analysis of the experiment?• The absolute answer to this question is probably not yet known, and will require simulation of the experiment to determine
the sensitivity of the measurement to a particular parameter. However, it is possible to make good guesses as to what these might be. These are the parameters which will be incorporated into the data stream of the DAQ. A typical parameter could be the value of the magnetic field as measured by the hall probes. It is the intention to gather a set of parameters whose importance can eventually be investigated by simulation.
2. CONTROL/MONITORING: Which additional parameters are needed for control or monitoring?• Additional parameters needed for control or monitoring which may not be part of the data stream but are necessary to
ensure proper operation of the equipment. This might include for example monitoring the status of interlocks or faults which are not relevant during MICE running.
3. How do you see these parameters being recorded and controlled?• It might be that the instrumentation, its control and monitoring has already been defined or there are already standard
methods/equipment used for this. This should be indicated here to so we can try to avoid duplication. If possible the nature of the hardware interface should be described.
4. What need do you have for stand-alone operation as opposed to integrated operation in MICE at RAL?• Will the equipment be operated outside of RAL during the commissioning or testing phase? If so what will be available at
the time of installation at RAL? If not what will be needed when the equipment is installed, commissioned and operated at RAL?

• 1. PHYSICS PARAMETERS: • Dipole Magnet Fields
– Pion and Muon Momentum– Target state
• target amplitude (actual) and beam loss signals = production rate
– Solenoid settings & quad settings = input emittance
– Diffuser setting = output emittance (of beam line)

• 2. CONTROL/MONITORING:
• Beam Line:– All magnets Qs (9), Ds(2), decay solenoid– Currents:
• Set & Monitored – feedback in power supply• Volts (read back);
• Alarms on temperature, cryogenics, vacuum etc drive a “status ok” signal

• 2. CONTROL/MONITORING:
• Target:– Synchronisation inputs:
• ISIS Machine Start (once per injection) • ISIS clock (200 kHz)
– Control Settings: • insertion depth • insertion time
– Operational monitors:• Up to 8 temperature measurements per cycle (inner coil, outer coil, cooling water
inlet, water outlet, ...)• alarm status = temperatures > pre-defined limits inhibit• The target position will be read every 0.1 ms and this information used internally to
adapt drive currents and timing. • Selected history stored for long term monitoring.

• Local Integrated system for beam line and target – power supplies, vacuum etc– Ethernet connection to outside world:
• Remote monitoring within restricted i/p range• Remote control within very restricted i/p range• PC/VME/PLC EPICS/LabView

• 4. What need do you have for stand-alone operation as opposed to integrated operation in MICE at RAL?
• Target testing away from RAL = standalone
• Beam line needs to be independent of MICE = Standalone at RAL
