'''AC''':
* Looking through waveform files for bad waveforms.
* No bad waveforms found searching by eye: '''ABF''' suggests using a higher rate dataset in order to increase the chances of finding bad waveforms.
* Will look at filtering peaks using built-in ROOT functions and throw away waveforms with double pulses.
* '''SJ''' will provide Matlab scripts for reading scope data: aim is to reconstruct energy spectra for scope data from 24th/25th November 2016 Clatterbridge run.

'''AK''':
* Converted August 2016 scope data from binary: data on <code>/unix/pbt</code>.
* Not sure if timebase conversion is working correctly: will try and train conversion code on November 2016 Clatterbridge data.
* Detector emulator producing waveforms with various time distributions: able to provide custom time distributions.

'''MH''':
* Running Clatterbridge simulations: using lateral surface mesh to count particles rather than looking at dose.
* Will meet with Lawrence to try to shorten simulation time (14 hours...).
* Intensity distribution at nozzle not quite flat: will look further upstream
* Managed to obtain Roisin Stephens' log book: not quite sure what most of it means...
* Will plot evolution of beam along beamline at each component.

'''ABF''':
* Working through data from November 2016 Clatterbridge run.
* Still see amplitude reduction at high rates, with the added Brucie Bonus of an amplitude increase around 200kHz...

'''LK''':
* Removed PMT from Geant4 simulations and introduced photodiode element.
* Photodiode counts photons! 21 photons per proton at Bragg peak.
* Need to optimise simulation parameters: will try and reconstruct Bragg peak from photodiode output.
* Will try some Geant4 visitation tutorials to resolve errors with OpenGL visualisation.
