  1. Control, Monitoring and DAQ Makoto Yoshida Osaka Univ. MICE CM @ Frascati June 28, 2005

  2. Brief history • Initiate work on control/monitoring and DAQ in the previous collaboration meeting in Berkeley • Edda surveyed on controls, instrumentation and DAQ • Jean-Sebastien distribute a draft of a new version of Edda’s note • DAQ-Terminology.doc • “Kick-off” DAQ meeting in lunch time on June 23 • Jean-Sebastien, Emilio, Paul, Alan, Koji and Makoto • Emilio prepared a skeleton for DAQ specification • DAQrequirements.doc • Will need a meeting with accelerator experts for further integration

  3. Prepared by Emilio Radicioni

  4. Categories • DAQ (O(mili-sec), every spill) • Detector-DAQ (O(micro-sec), every trigger with spill#-stamp) • detector data • ADC / TDC • Beamline-DAQ • cooling channel • RF voltage / phase • oscilloscope or flash ADC • others? • protons on target • 2ndary particle intensity monitor • Slow control/monitor (O(sec), continuously even when DAQ is not running) • beamline • magnet currents / temperature • cooling channel • RF temperature • LH2 absorber temperature • solenoid currents / temperature • detectors • Temperature • HV

  5. DAQ • Each sub-group is developing stand-alone systems • Gather the data stream to the event-builder • For every particle or for every spill • Synchronization between the systems • Spill number stamp • Event numbering in each detector • Time stamp by common clocks? • Need to develop a communication between the stand-alone systems • Determine interface/protocol • Data structure

  6. Slow control • Each sub-group develop stand-alone systems • Strongly related to safety issue • Gather the consoles in a control room • Develop a communication between the stand-alone systems, if they need • Need to determine interface/protocol

  8. Key issues • Instruments for each sub-group • Voltage controller/monitor • HV controller/monitor • CAENET • VME ADC/TDC • … • Communication between stand-alone systems • Socket on TCP/IP • Log files on common directory • … • Integration • Event-builders • Event numbering • Unified interface or distributed controls to stand-alone systems • … • Offline database

  9. Summary • DAQ group start to discuss on the integration • Need to fill the documents on DAQ specification • Description on the systems of each sub-group • Integration, Synchronization • To build up MICE control/monitor and DAQ system, communication with accelerator experts is mandatory • Workshop in RAL?

  10. Survey on Controls, Instrumentation and DAQ • PHYSICS PARAMETERS: Which parameters might it be important to include in the data analysis of the experiment? • CONTROL/MONITORING: Which additional parameters are needed for control or monitoring? • How do you see these parameters being recorded and controlled? • What need do you have for stand-alone operation as opposed to integrated operation in MICE at RAL?
