View source for 25mA, 100ns pulse width, 50cm from beam pipe

Changed distance from end of beam pipe from 25cm to 50cm. 

Cut current by a factor of 4. 100mA->25mA

Assuming <math>25\frac{mA}{pulse}</math> and a pulse width of <math>100ns</math>

Then <math>25\frac{mA}{pulse}=25\frac{mC}{s*pulse}=0.025\frac{C}{s*pulse}</math>

<math>0.025\frac{C}{s*pulse}(100ns)=2.5*10^{-9}\frac{C}{pulse}</math>

<math>2.5*10^{-9}\frac{C}{pulse}*\frac{1\ e-}{1.602*10^{-19}}=1.56055*10^{10}\frac{e-}{pulse}</math>

===OSL===

<math>\frac{1}{1000}</math> of a pulse. ~15mil e- simulated, ~15bil e- per pulse. With beam parameters given above.

Deposited Energy: <math>9.29701*10^{5} MeV</math>

OSL geometry: 0.501cm diameter cylinder of 0.03cm thickness with beam incident on flat face. 

OSL Crystal density<math>=3.9698\frac{g}{cm^{3}}</math>

Mass of a single OSL crystal: <math>(\pi(0.2505)^{2}*(0.03))*(3.9698)=0.0234777g</math>

Scaling deposited energy by 1000 to account for only shooting a 1000th of a pulse, the deposited energy becomes <math>9.29701*10^{8} MeV</math>

Converting to Joules for dose calculation: <math>9.29701*10^{8} MeV=1.48938*10^{-4}J</math>

Average dose per pulse: <math>\frac{1.48938*10^{-4}J}{0.0234777*10^{-3}\ Kg}=6.34381\ Gy=634.381\ rad</math>

===Quartz===

<math>\frac{1}{1000}</math> of a pulse. ~15mil e- simulated, ~15bil e- per pulse. With beam parameters given above.

Deposited Energy: <math>9.21601*10^{7} MeV</math>

Quartz Geometry: 1 inch diameter, 0.5 inch tall cylinder with electrons incident upon the base of the cylinder. 

Quartz density<math>=2.32\frac{g}{cm^{3}}</math>

Mass of Quartz used in simulation: <math>(\pi(1.27)^{2}*(1.27))*(2.32)=14.9296g</math>

Scaling deposited energy by 1000 to account for only shooting a 1000th of a pulse, the deposited energy becomes <math>9.21601*10^{10} MeV</math> 

Converting to Joules for dose calculation: <math>9.21601*10^{10} MeV=0.0147657J</math>

Average dose per pulse <math>\frac{0.0147657\ J}{14.9296*10^{-3}\ Kg}=0.98902\ Gy=98.902\ rad</math>
