| 1 | 1 | Nebrensky, Henry | h1. BLOC training 15 September 2013 |
|---|---|---|---|
| 2 | |||
| 3 | This is a training/revision session for BLOCs. |
||
| 4 | 2 | Nebrensky, Henry | Anyone who has not gone through the revised [[BLOCtraining|training schedule]] cannot act as BLOC in the upcoming run. |
| 5 | 1 | Nebrensky, Henry | |
| 6 | I know it's an awkward date - but that's the only time we could get. |
||
| 7 | |||
| 8 | 9 | Nebrensky, Henry | h3. Attendees -(N.B. max. 6 in MLCR) |
| 9 | 10 | Nebrensky, Henry | |
| 10 | 9 | Nebrensky, Henry | * Ed Overton |
| 11 | * Henry Nebrensky |
||
| 12 | * Pierrick Hanlet |
||
| 13 | * Ian Taylor |
||
| 14 | |||
| 15 | 11 | Nebrensky, Henry | h2. Advanced Target & PPS training session |
| 16 | 1 | Nebrensky, Henry | |
| 17 | h3. PPS (I) - 9:00 |
||
| 18 | |||
| 19 | Will run target with Muon Test permit, will cover how to start setting up PPS without mimic. |
||
| 20 | |||
| 21 | h3. Target Theory - 9:30 |
||
| 22 | |||
| 23 | 0) a) How the target works (explanation by poster) |
||
| 24 | b) Control systems and Vac Rack (inc. access) |
||
| 25 | c) Walkabout checklist items |
||
| 26 | |||
| 27 | 1) a) Target powerup (can be done with frame raised) |
||
| 28 | b) Basic (shifter-level) operation |
||
| 29 | c) Monitoring plots and reports |
||
| 30 | d) Checking the Target is operating to the correct spill (can be done with frame raised) |
||
| 31 | e) Checking the beambump is active |
||
| 32 | f) PPS interlocks; PPS vs BPS, etc. |
||
| 33 | g) MICE Controlled Entry procedure |
||
| 34 | |||
| 35 | h3. Dipping into ISIS - 10:00 |
||
| 36 | |||
| 37 | 2) a) Finding the ISIS Beam |
||
| 38 | b) Checking the next spill injection losses (i.e. setting too long or short user delay). |
||
| 39 | c) Optimising timing (playing with user delay to optimise beam loss profile) Intrusive / Requires help from ISIS: |
||
| 40 | |||
| 41 | h3. "Intrusive" activities - 11:30 |
||
| 42 | |||
| 43 | 3) Running without the beambump (and how it changes everything!) |
||
| 44 | Needs ISIS to turn off beambump temporarily |
||
| 45 | |||
| 46 | 4) a) Overview of ISIS BLMs and trips (minor vs major, I forget the terminology) |
||
| 47 | Would it be possible to get this from Dean Adams or ISIS directly? |
||
| 48 | b) Run at the margin to try to see some of the minor trips (this would |
||
| 49 | be better done with the beamloss limit reduced to say 1V to reduce |
||
| 50 | jitter) |
||
| 51 | |||
| 52 | 5) Example of a BPS Trip (and what to do!) |
||
| 53 | |||
| 54 | h2. Magnets - cooling water etc. - after lunch |
||
| 55 | 3 | Nebrensky, Henry | |
| 56 | 8 | Nebrensky, Henry | For future reference, _some of this_ would be done better during the shutdown. |
