'''DW''':
* Making progress with [http://www.hep.ucl.ac.uk/pbt/wikiData/presentations/2018/DW_LeCroyData_31-01-18.pptx extracting data from Leroy binary files]:
** Aim is to load LeCroy waveform files, identify pile-up, calculate ADC counts and do it quickly.
** Previously used χ<sup>2</sup> for selecting bad pulses; Schmitt trigger on rising edge faster.
** Integrating whole pulse gives broader peak with larger mean than Caen.
** Shortening integration window makes LeCroy peak match with Caen, even for low counts.
* ''To Do'':
** Update information on Wiki.
** Badger '''Tony Price''' for tracker files!!.
** Work out how to calculate incoming trigger rate for LeCroy scope.

'''JS''':
* Reanalysed scintillator sheet thicknesses:
** 3 mm sheets are closer to 2.75 mm but variation is mostly below 100 microns.
** 2 mm sheets have 2 groupings:
** 2.0 mm group has better flatness than 2.6 mm group.
** Thickness sigma of 3 mm sheets 90% below 30 micron target.
* Continuing to work on Clatterbridge simulations:
** Needs a list of things to do!
* ''To Do'':
** Write up scintillator sheet measurements and post iPython notebook with analysis.
** '''MH''' will but '''JS''' in touch with '''Jactina Yap''' to include more components in beamline.

'''MH''':
* Update from '''Jacinta Yap''' on Clatterbridge:
** Spoken to Andrzej Kacperek about positions of cap and nozzle: positions and locations shouldn't make difference to treatment.
** Dose monitor foils are 20 microns with air gap in between of 2 mm.
** '''Jacinta''' needs to know input parameters, particularly energy and energy spread.
* Trying to replicate bug in buffered readout for Geant4.
* Currently compiling Geant4 on Virtual Machine on '''new''' MacBook.
* ''To Do'':
** Buffering of readout in Geant4.
** Put '''JS''' in touch with '''Jacinta Yap'''.
