Linac Run Plan April 2018, Dr. McNulty
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
Start at 7am
Shot # Number of Pulses Number of OSLs Beam Current Dose/pulse Expected Dose/pulse 1 80 1 50 mA 2 1 mA 3 1 mA 4 1 mA 5 1 mA 6 1 mA 7 1 mA 8 1 mA 9 1 mA 10 1 mA 11 1 mA 12 1 mA 13 1 mA 14 1 mA 15 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
Will talk to engineers about double pulsing and guaranteeing number of pulses and update.
