- Delivered update on Geant4 simulation development, slides can be found here.
- Found a list of values for Gaussian energy straggling to produce curves similar to those measured at UCLH, across clinical energy range.
- Added detector messenger to allow Birks' constant to be set at runtime.
- Gave presentation on analysis on PARTREC beam test, slides can be found here.
- Beam quality worsens at lower energies, possibly due to aluminium beam degrader.
- Appear to have linear scaling of average charge measured with beam current.
- Fit results do vary with different beam current: effect is more pronounced at lower (worse) energies, best results still have 0.1-0.2 mm difference in range.
- There is some interplay with Birks' constant and range – worse values of Birks' constant give worse range results.
- Possibly have 0.8mm systematic offset from reference data, but need more reference data to confirm.
