	* Update on [http://www.hep.ucl.ac.uk/pbt/wikiData/presentations/2018/ABF_groupMeeting_10.01.2018.pdf single module detector simulations and scintillator paint tests]:		* Update on [http://www.hep.ucl.ac.uk/pbt/wikiData/presentations/2018/ABF_groupMeeting_10.01.2018.pdf single module detector simulations and scintillator paint tests]:
	** ~~Was~~ smearing ~~pre and post simulations: post-simulation always used 8.5%;~~ now ~~only smearing pre-simulation with variable~~ resolution.		** Larger FWHM smearing now shows increase in spread in detected resolution.
	** ~~Now correlation~~ between ~~Monte Carlo truth~~ and reconstructed energy ~~spectrum~~.		** Still a difference between MC Truth and reconstructed resolutions.
	** ~~Still seeing low~~ energy ~~tail~~.		** MC Truth calculated purely from detector resolution: reconstructed resolution also includes beam energy spread.
			** When subtracting in quadrature, offset is almost constant: intrinsic energy resolution in the beam?
			** Will check energy spread on Matthieu's beam and also rerun simulations with mono-energetic pencil beam.
			** Paint tests with scintillator show large decrease in light output.
			** Increase in signal/noise results from lower photon statistics.
			* Paper should be ready in draft form by end of January.

	'''LK''':		'''LK''':
	* ~~PPRIG was good!~~		* Set up Nikon D70 camera from Adam Gibson to take images remotely.
	** Mike Merchant wants particle spectra for Geant4-DNA simulations.		* Will check with '''Michaela Esposito''' whether we can use PRaVDA ISDI sensor.
	** Very helpful comments during evening meal...		* Spoken to ISDI about commercial sensors: waiting for datasheet.
	** Not sure whether initial proton retains 'primary proton' ID.
	* Everything should be finished with paper:
	** Waiting for Adam to ~~write his parts and polish off~~.
	** Clinical part needed from Richard Amos.
	** No answer from Tracey Underwood: becoming less likely...
	* Lots of code housekeeping!
	* Will ~~contact~~ '''Michaela Esposito''' ~~and '''Tony Price'''~~ about ~~ISDI~~ sensors.

	'''JS''':		'''JS''':
	* ~~Gone back to looking into~~ CAD modelling in Geant4.		* Working through CAD modelling in Geant4:
	* ~~Going through Matthieu's Clatterbridge simulations:~~		** Should be able to import GDML files into Geant4.
	** ~~Learning how simulations run~~.		** Autodesk does not support GDML...
	** Investigating introducing sensitive detectors for ~~particle measurements~~.		** Need bridging software to do conversion: FreeCAD GDML and FastCAD, both of which have drawbacks...
			* Running into problems with OpenGL visualisation for Clatterbridge simulations.

	'''DW''':		'''DW''':
	* ~~Improved~~ code ~~to integrate waveforms~~.		* Bug-hunting in binary conversion code: some integrals coming out negative...
	* Reconstructed Caen ADC spectrum: needs corresponding LeCroy binary files.
