JS:

Working on different visualisers for tutorials.
Tried using Google visualisation package (the name of which escapes us...).
Waiting on information from Tony Price on Geant4 visualisation: SJ will chase up...

ABF:

Detector simulations now include hexagonal module and Clatterbridge nozzle collimator.
Trying to pin down origin of non-Gaussian shape of ADC peak from Clatterbridge data:
- Background measurements do show low energy peak but nothing at high energies.
- Low energy peak slightly reduced due to absorption in 4cm PMMA.
- Using Matthieu's latest simulations with 2mm collimator does show a non-Gaussian shape on main peak but not large enough.
RS suggests putting an angle on the collimator in MH's simulations to check the effect.
Also modifying mylar thickness to

RS

Still working with Hamamatsu to provide PMT for single module:
- Supply last dynode stages in PMT from 2 HV PSUs.
- Concern over no limiting resistor between HV and dynode...

MH

Welcome back!
Courses start next week: will add in some Medical Physics courses.
Will look into rerunning Clatterbridge simulations to provide input for Anastasia:
Split beamline into 3 sections:
- Up to 1st collimator (doughnut).
- Between doughnut and stopper.
- After stopper.
