	'''SJ''':		'''SJ''':
	*		* Next stage beyond WEPL fast QA device is fast treatment plan verification:
			** Tracking layer measures individual spot profile in 2D.
			** Calorimeter measures longitudinal dose deposition profile.
			** Reconstruct both spot by spot to give 3D dose distribution for each pencil beam spot.
			** Build up 3D dose distribution using information from each spot.
			* '''Tony Price''' and '''Phil Allport''' at Birmingham has £20k from STFC Network+ (Karen Kirkby) to build prototype:
			** Take PRaVDA single tracking layer.
			** Measure position of 1 proton at a time at ~1 kHz.
			** Also measure proton energy with single module calorimeter.
			** Time acquisition such that we know position and energy of each proton.
			* This requires timing together PRaVDA tracking with our calorimetry:
			** PRaVDA uses 26 MHz(?) clock (synced to iTHEMBA cyclotron frequency) with 1 "frame" per clock cycle.
			** PRaVDA DAQ built by ASPECT: will provide timestamped "event" with proton location.
			** Can use PRaVDA tracker to trigger our calorimeter DAQ: probably use scope.
			** Need to read out header from scope binary file to get precise trigger information.
			* Future detector will need better DAQ:
			** '''Matt Wing''' has suggested using EUDAQ generic detector DAQ as software back end.
			** EUDAQ also includes Bristol Trigger Logic Units (TLUs) to aggregate digitised data and create an "event".
			** '''MW''' has offered some of '''Sohail Amjad's''' time to work on proton calorimetry DAQ.
			* '''DW''' will look into LeCroy scope binary files to see if we can get rudimentary trigger information to link with PRaVDA tracker events.
