I have attached a pdf of a series of slides with some multiplicity and hit pattern plots on, also a list of cuts. As well as this I looked at how many
'good hits' (explained in pdf) I am getting per event.
Before Christmas I found that the code was not clearing the raw arrays read in by MIDAS and so unless a new piece of data filled the array channel |

We have been running smoothly all night. Only problem is that the DAQ occasionally does not start properly after a stop-go. The dead-time goes
to nearly 100%. This happened twice in the night,. and a second stop-go did the trick. Needs looking at.

Tue Dec 4 05:40:10 2012, Jessica Tomlinson, Other, Other, analysis - single strip E vs t 6x
|
I have attached some single strip energy vs time plots to show that the structure seen in the collective E vs t plots is in each strip.
Attachments 1 and 2 show two different strips in S2-2 with no cuts. You can see that the 3 loci are different to one another in the single strips
as well as in the combined S2-2 E vs t plot shown in attachment 3. Attachement 3 is plotted after applying the following cuts: equal energy in the front |

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. |

Update:
W decided at 8.00 to stop, check the tune, retune and get back going. This has nearly, finished but it is a very long process indeed - note for
future - this takes AT LEAST 12 hours, if one is systematic about it. |

The thick carbon target, to be used for background runs for the thick CH2 measurement was supplied by Marek.
He measured it to be 120um thick (with a micrometer), and says it's low density carbon (1.03g/cm3).

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 |

Mon May 23 02:12:14 2011, Brian, Routine, , Start of Run summary
|
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 |
