Beam Line info
0 degree line
Aluminum window = 0.5mm thick. Radius = 23.813mm
Air gap between Aluminum window and glass slide = 45mm
Glass slide Thickness = 1mm
Run Plan
To find operating point
- Will use 15 OSLs from reproducibility study to make sure that dose is within acceptable range
Experiment
85 Nanodot OSLs for use (dose not include OSLs from reproducibility study)
- upper limit of OSLs is 15Gy, want to be around 7.5Gy with multiple pulses
Machine: 25b Linac
Beam Energy: 8 MeV
Rep Rate: Max (150Hz)
Will talk to engineers about double pulsing and guaranteeing number of pulses and update.
