ELogs/JeremyOcampo

Electronic Log for Jeremy Ocampo.

To do

G4 Simulate an image from a 1mm thick scintillator in a non-scintillating plastic slab
- compare to image from thick scintillator block
- this is to test the idea that we are seeing errors due to focal depth or light coming from different depths
G4 Get profiles at different depths and compare to data
G4 Get output factor curves and compare to data
G4 Make code neater, add more macros
Report Finish first draft of start of report.
Camera Familiarize oneself with DSLR camera and software

Workshop Went to workshop - "Challenges and opportunities within practical small field dosimetry" - 9th may
G4 Simulate image from a 10cmx10cmx20cm scintillator and compared it's pdd with image from dslr camera.
- ~100,000 optical photons collected by lens given ~10,000,000 x-ray photons, which took 3 hours.
- reduced computing time using multithreaded mode, and also using the symmetry of the system and adding more lenses to collect more light
G4 Import phase space file (cyberknife) beam to use as primary generator.
Group placement exploring the simulacrum cancer data from PHE - 12th april
2nd term courses Machine learning with Big data, Inverse problems in imaging
G4 Learning Geant4 with:
- ED-Geant4 - Lectures with exercises and solutions from an intro G4 workshop in 2018.
- Geant4 book - Reference for G4.
