HPTPC analysis and software meeting

Europe/London

HPTPC 05/04 meeting

 

Attendees: Brailsford, Deisting, Haigh, Jones, Chen-Wishart, Richie-Yates, Monroe, Nichol

 

Round table update (progress slowed due to statistical fluctuation in number of non-hptpc meetings)

 

CCD (absent)

 - Currently tuning Gaussian blurring on the propaganda event

 - Method is to maximise integral around the track

 - The gaussian blurring has been run for an initial set of parameters; analysis to be done

 

Waveform (A.D.)

 - waveform trigger - spill trigger == 0 was comparison of the spill triggered waveform to itself

 - Beam analysis run over 700 files (calculates the beam spill time)

 - Two tasks TODO:

  - Add the beam trigger signals into the raptor TPC waveforms

  - Add are_spill_times_present to raptorr header

Gain measurements talk (H.R.Y)

 - Study of source data taken in november

 - Cases shown where amplitude may be mis-measured due to baseline below dynamic range and also saturation

 - Gain analysis being reproduced in raptorr

 

Global (absent)

 - Bug fix for utof/dtof matching analysis so that the equivalent plot to the flux paper can be made

  - There are currently differences between the two plots; being investigated

 - TPC-TOF global spill event formation logic works and has been tested on a very specific small subset of files (J.H.)

 - TODO: include TPC spill times in DB

 - TODO: multi-file functionality

 

Hardware update (Z.C.W.):

 - Trial run of the halls for moving the TPC to the clean room

 - Working on support frame

  - Almost ready to order parts

 

Intr. paper (A.D.):

 - Progressing with writing

 - E.T.A for end of month

 

S3 Deadtime in flux analysis talk (S.J.)

 - Recap of problem and potential solution

 - 4 moderator block data did not fit pattern seen for other block data 

 - Dependence of dead time on number of hits seen in s4

 

Flux paper update (S.J.):

 - List of comments sent to Seb which have been added in

 - Conclusion section still TODO

 

AOB:

 - Ed will update his poster and then ask for a new round of comments
