General

Profile

Lingo

  • AFC: Absorber Focus Coil
  • base rate: ISIS pulse rate during machine-physics or troubleshooting. Strictly, base rate is MS/64 (or ~0.8 Hz); stability issues with the ion source mean that extended operation is usually at MS/32 (or ~1.6 Hz).
  • BLM: Beam Loss Monitor. Four of these are located along each ISIS sector, and their real-time output is the infamous barchart on the monitor on the MLCR wall.
  • BPM: On MICE, the FermiLab Beam Profile Monitors. (Note that in common accelerator-speak this would stand for Beam Position Monitor)
  • BPS: Beam Permit System. Protects ISIS beam operations from issues with the MICE target.
  • CDM: Construction Design and Management, see also http://www.hse.gov.uk/construction/cdm.htm.
  • CKOV: Cherenkov detector, sometimes spelled Cerenkov or ńĆerenkov
  • Counting Room: obsolete early name for Rack Room 1
  • DAQ: data acquisition
  • DL: Daresbury Laboratory
  • DS: decay solenoid
  • East Wall: The wall closest to ISIS
  • EMR: Electron Muon Ranger
  • G4MICE: The predecessor to MAUS.
  • ISIS: a pulsed neutron and muon source at RAL, more at http://en.wikipedia.org/wiki/ISIS_neutron_source
  • LH2: Liquid Hydrogen
  • LM: Luminosity Monitor. A counter located within the ISIS synchrotron, allowing normalisation of particle production rates from the MICE target.
  • machine physics: Scheduled period for set-up/testing/debugging of ISIS itself.
  • MAUS: MICE Analysis User Software. The simulation used by the MICE experiment based on the Geant4 MC tracking library
  • MC: Either Monte Carlo simulation or Muon Collider
  • MCR: ISIS Main Control Room - not to be confused with the MLCR
  • MICE: Muon Ionization Cooling Experiment
  • MICO: MICE Installation, Commissioning and Operations, MICO webpage
  • MLCR: MICE Local Control Room
  • MOM: MICE Operations Manager
  • MS: ISIS' Machine Start signal - a train of pulses at 50 Hz used to synchronise equipment within ISIS, and MICE. During normal operation each MS pulse triggers an ISIS pulse, hence during User Run mode ISIS operates at 50 Hz. The MS signal is repeatedly halved for other operating modes, and for triggering the MICE Target.
  • NF: Neutrino Factory
  • NIM: Nuclear Instrumentation Module standard or Nuclear Instruments and Methods journal
    • NIM crate: standard chassis NIM modules can be plugged into
  • North Wall: The wall opposite the control room
  • PID: Particle IDentification
  • POMPOMs MICE Beam polarity monitors. The obvious abbreviation is taken.
  • PPS: Personnel Protection System. Ensures anyone entering the Hall is safe from hazards generated by MICE operation
  • RAL: Rutherford Appleton Laboratory, one of the national scientific research laboratories in the United Kingdom operated by STFC
  • RFCC: RF Coupling Coil(s)
  • RR1: Rack Room 1 - the original rack room adjacent to the MLCR, housing DAQ readout electronics and computing
  • RR2: Rack Room 2 - additional space for magnet control and power racks
  • S1/S2/S3: successive examples of the newer target mechanism design (stator). At each refurbishment a new shaft and bearings are fitted, denoted by a decimal point; thus S1.8 would be the 8th incarnation of the S1 mechanism. See also T1.
  • South Wall: The wall closest to the control room
  • spill marker: a signal from ISIS designating the particular ISIS pulse into which the MICE target may be driven - appropriate beamloss limits or beam bump may be applied only to that specific pulse.
  • STFC: Science and Technology Facilities Council
  • SS: spectrometer solenoid
  • T1/T2/T3: refer to the earlier Target1, Target2 and Target3 mechanisms - see S1.
  • TOF: one of three time-of-flight detectors
  • Unpacking: Unpacking is the process that takes the DAQ readout and converts it to particles. The program that does this is the 'unpacker'
  • West Wall: The wall closest to the equipment (large) hall door.
