JO:

Managed to run Geant4 photon tutorial by connecting from Windows/Mac laptops to plus1.
Cannot view or analyse results: issues with running ROOT over SSH.
MH will assist with setting up relevant software environment on Mac.
Going through reading list provided by Jamie McClelland and Adam Gibson.
To Do:
- Install MacPorts and ROOT on Mac.
- Try both local and remote data analysis.

MH:

Pure Geant4 pCT simulation matches results from GATE.
Reconstruction not quite working: resulting image does not represent actual object.
Possibly to do with matching up pairs of protons from pre/post object: might be possible to assign individual proton ID.
Issues with merging results from multiple simulations: cannot use more than 70,000 particles per simulation.
To Do:
- Contact Simon Rit to discuss reconstruction issues.
- Contact Ben Morgan at Warwick to find solutions to simulation merging issues.

OM:

Starting working on Geant4 simulations.
Reading up on C++: SJ suggested getting started with the same tutorials as JO and MH.
Plan of action is to work from Geant4 to BDSIM, then add in CAD modelling, before improving CAD model.

SS:

Looking through data from Birmingham experimental runs.
Results generally look good:
- Clear double peak for eyepatch data.
- Some spectra show unexpected double peaks: SJ suggests PMT rate effects.
To Do:
- Analyse scope data by Christmas.
- Take data for LeCroy scope trigger rate test.

FFF:

Will be working on front end detector electronics design and readout for project.
Identified possible photodiodes for range calorimeter.
Contacted Hamamatsu but specific photodiode not available: will discuss with Anastasia Basharina-Freshville and SJ to contact Hamamatsu rep directly.
