'''AC''':
* Working on analysis of scope waveform data.
** ROOT will now identify bad pulses!
** ROOT TSpectrum will analyse waveforms for double peaks based on histogram distribution.
* Will next try and fit to good waveforms to train pulse filtering and integration.
* Anastasia suggests looking at low and high rate files with no absorber.
* Will also complete Java code to import binary files directly into ROOT: need to include input arguments.

'''AK''':
* [http://www.hep.ucl.ac.uk/pbt/wikiData/presentations/2017/AKnoetze_25.01.2017.pdf Looking at various output spectra from Caen detector emulator.]
* Trying to set spectrum of waveform magnitudes (Caen instructions plus trial and error...).
* Taking average of "large" waveforms to produce mean waveform for emulator.
* Detector emulator time resolution much coarser than scope data (~160MHz): need to extract subset of individual waveform data to produce approximation of our waveforms.
* Next step is to put output of detector emulator into digitiser and try and recreate Clatterbridge results.

'''MH''':
* [http://www.hep.ucl.ac.uk/pbt/wikiData/presentations/2017/mhentz_beamline_characterisation_11-01-2017.pdf Clatterbridge simulations: now running 1 million events:]
** Split simulations and submitted to batch farm: reduced simulation time from 24 hrs to 30 mins.
** Will look into longer simulations using different batch farm queues.
* Updated beamline construction with second dose monitor.
** Will put together diagram with coordinates, dimensions and materials to send to Clatterbridge to check dimensions.
** Will also collate results to send to '''Carsten Welsch''' at Liverpool for review.
