Wed Apr 13 03:43:42 2011, Jamie, , , Ni window leak tests 1
|
2um x 8 mm Ni windows leaked tested on TUDA gas cell. With window placed on the outside of the cell, cell was evacuated and pressure monitored with time,
i.e. 1atm differential air pressure. Comparison to leak rate with blank flange also do.
Tests were performed in order: Ni, 30 minuets pumping, Ni again, blank, Ni third time. |

Attached plot shows rate of pressure increase in ~2l volume upstream of TUDA with Ni window #2 installed on reentrant flange. Comparison between
a)pumping out TUDA and 2l volume, and
b) filling TUDA with ~340mbar of He and pumping out 2l volume. |

Wed May 11 17:59:12 2011, JB, , , Re-entrant flange alignment
|
Alignments checks revealed that downstream end of TUDA was ~1mm off (can't remember which way).
Re-entrant flange (window end) found to be ~5mm too low and ~2mm to the left. Checked upstream end of chamber and was ok.
Removed bellows etc. and re-entrant flange, replaced with re-entrant flange bolts only figure tight. Tighten bolts from inside chamber whilst checking |

Sarah informed me that Jamie was performing the sorting and saving of spectra differently and didn't know what exactly to do so I will not be performing
any sorting.

Handover from last shift was...
1. Running at 4.11 MeV/u at about 15enA (5+)
2. Would like to take more beam but already at situation where deadtime about 50%. They have been raising thresholds on the inner strips |

Summary at start of run
Read through the runbook and end of run summar and the situation appears to be:
1. The check of the tune showed it was OK, although a bit of beam (or halo) clipping 4mm collimator |
|
Wed May 25 07:09:17 2011, Brian, Routine, General, End of run summary (yes, a bit early, but done all I can think of!)
|
Running status
Everything seems to be running OK. ADC and TDC spectra look OK. Chamber pressure has stabalised. Detector leakages stabalised
Beam now up to 60pnA with trigger rate about 4,000/s and accepts about 3,000/s |

No major problems presented, A pluser walk was performed at the begining of the shift run161 S2-1 front, run162 S2-2 front, run163 S2-1 back and run165
S2-2 back.
Runs 166, 168, 169 are void due to bad scaler reading |
