Working group reports
CCD
- Index bug.
- Dimensionality of histogram bug found.
- All pixels are discretised in units of 0.25 ADU. Raw images should be integers. To be double checked.
- Spark killer being updated so that a spark in one image kills all 4 images
Waveform
- No RAPtorr development
- Being used for analysis now
Global
Other
- Talk by Ed
- Beam database development - extracts information from current DBs
- Information from elog used to find runs with specific parameters: No. Moderator blocks, collimator change, electron target change etc.
- Magnet current vs time presented, shows periods of long term change and some significant outliers.
- Followup questions with CERN beam group regarding measured 0 current points
- Database farm access - an ongoing battle. An email to sys-admin is needed
- If multiple access is a problem, may be necessary to implement a ’smart’ job submitter
- Need to check where DMTPC database is located and check their methodology
- Time distribution of TPC waveforms shown for all anodes
- #TODO
- Apply threshold to remove KeV electron bursts
- Suggestion to plot pulse height vs time
CCD Labelling
- CCD index stored in dmtpc/raptorr does not correspond to the indices used in various codes in dmtpc; the element on the CCD vector is used instead.
- Change implementation so that the camera config struct’s ccd_index variable tracks the vector element index.
ToF analysis
HPTPC instrumentation paper
- No updates for this week
- Internal deadline for mid-end February
Beam flux paper
- Focussed on flux analysis, writing to follow.
RAPtorr workshop discussion
- Investigate reconstruction prior to next workshop
- Team CCD should push forward on implementing a first draft of clustering in the next week
- We will need a simulation to develop the reco + selection
- Further discussion of plans and goals at next meeting
AOB
- Alexander will send his VCI2019 talk around later today. Please read.
