Double dip rate¶

Monday at 13:00 GMT 25th November 2013

• Motivation for double dip rate (Rogers)
• Status/plans of DAQ for double dip rate (Karadzhov)
• Status/plans of target for double dip rate (Smith)
• Operational constraints e.g. RF work in hall (Hanlet)

Notes¶

• Motivation for double dip rate (Rogers)
  • Request from ISIS to reduce instantaneous dose
  • Tracker group deadtime issue
• Status/plans of DAQ for double dip rate (Karadzhov)
  • Yordan was not present
• Status/plans of target for double dip rate (Smith)
  • Target in ISIS has probably operated at 50/64 in R78
  • Target will run hotter
  • Need to test
    • Changed timing settings wrt ISIS beam start (due to different operating temp)
    • Possibly different BPS settings
    • HN notes: PS mentioned that changing BPS settings will need specific permission. Possibly Alan Stevens?
    • Compare with the dip depth
  • Would like updated target DAQ
• Operational constraints in the MICE Hall (Hanlet/All)
  • Could not find documentation on our operation of the experiment at all
    • i.e. no documentation that we can operate the experiment with the current PPS system
    • HN: MICE Note 175 Addendum implies it's up to MICE Collaboration to produce own written procedures (item 3) - where are they kept though?
  • Three questions to answer
    • HN re-phrases: What are the constraints on when the Activation Study takes place? Can it happen during any ISIS start up?
    • Can we run with D1 and D2 switched off, beam stop up, and hall open?
    • Can we run when the RF tests are not being done e.g. weekend/evening?
• Paul Smith to present slides at the next VC?
  • Pass them round email list beforehand
