Lexicon

  • AFEB: Anode front end board. Amplifies, shapes, discriminates and presents the anode signals to the ALCT.
  • ALCT: 1 Anode local charge track, an LCT amongst the anode data. 2 Anode local charge track board. On chamber-electronics that processes data from the AFEBs and generates an LCT, also packages anode data in a buffer to be streamed to the TMB.
  • BNC: Berkeley Nuclear Corporation. Defines a connector standard.
  • BXN: Bunch crossing number. A number that is assigned to each collision. This number is incremented every 25ns, which is the period of collisions at the LHC.
  • CAMAC: Computer Automation and Control. A packaging standard for electronics and a standard for DAQ. A DAQ-oriented bus is defined.
  • CCB: Clock and control board. Distributes TTC signals to the front end so that all detecting elements present synchronized data with the correct BXN tag.
  • CERN: European Organization for Nuclear Research. A laboratory with a large particle collider outside of Geneva, Switzerland (website).
  • CFEB: Cathode front-end board. On-chamber electronics that collects cathode strip data.
  • CMS: Compact muon solenoid. A collider detector. The original design by Carlos Rubbia envisioned a high-field solenoid, a hadron calorimeter within the solenoid and muon tracking outside of the thick solenoid's iron. It was imagined that the muon signals themselves would give much interesting physics.
  • CLCT: 1 Cathode local charge track, an LCT amongst the cathode data. 2 Cathode local charge track board, historically, a board that sought an LCT among the cathode data.
  • D360: A microcontroller that performs DCS functions and serves as a VME crate controller.
  • DAQ:
    1 data acquisition
    2 data acquisition system.
  • DAQMB: Data Acquisition Mother Board. Designed by OSU. Collects data from the CFEBs
  • DCS: Detector control system. A way to configure and monitor the detector's infrastructure.
  • DMB: synonym of DAQMB Documentation: Like love, there is never enough of this in the world.
  • EMU: The endcap muon system. The EMU and the Barrel muon detectors together form the muon detection system originally envisioned for CMS.
  • FAST: Final Assembly and Subsystem Test
  • Front end: That part of the electronics that is closest to the actual detecting element.
  • L1A: Level 1 accept. The signal that comes back from the level 1 trigger to begin a dump of the front end so that the data are collected by the DAQ.
  • Level 1 trigger:
    1. Synonym of L1A
    2 The trigger circuitry that collects chamber LCT's and other information from the all detecting elements of the CMS detector, and generates the L1A. This decision must be made at exactly 2.9us after the generation of the original CLCT or ALCT.
  • LCT: local charge track. Can originate from the anode section or cathode section. Indicate a high probability that a track exists.
  • LHC: The large hadron collider at CERN.
  • MPC: Muon port card. A fast board that streams muon data to the DAQ from a VME crate.
  • NIM: Nuclear Instrumentation Module. A packaging standard for electronics. Only a power supply bus is defined.
  • Slow control: A synonym for DCS.
  • TMB: Trigger Mother Board. Designed by UCLA. Historically, the TMB simply correlated local charge tracks between the anode and cathode section. Now, the TMB also contains both this function and the CLCT function. The TMB is responsible for sending a chamber-wide LCT to the Level 1 trigger.
  • TTC: Timing and trigger control. The means by which the experiment timing is controlled.
  • VME: Versa Module Europa. A packaging standard for electronics. A microprocessor-like bus is defined.
