Beam Line info
0 degree line
Titanium window = 0.5mm thick. Radius = 23.813mm
Air gap between Titanium 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
Table
Shot # Start Time End Time Number of Pulses Number of OSLs Beam Current 1 7:00am 7:05am 80 1 50 mA 2 7:10am 7:15am 1 mA 3 7:20am 7:25am 1 mA 4 7:30am 7:35am 1 mA 5 7:40am 7:45am 1 mA 6 7:50am 7:55am 1 mA 7 8:00am 8:05am 1 mA 8 8:10am 8:15am 1 mA 9 8:20am 8:25am 1 mA 10 8:30am 8:35am 1 mA 11 8:40am 8:45am 1 mA
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.
