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

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

Then <math>100\frac{mA}{pulse}=100\frac{mC}{s*pulse}=0.1\frac{C}{s*pulse}</math>

<math>0.1\frac{C}{s*pulse}(100ns)=10*10^{-9}\frac{C}{pulse}</math>

<math>10*10^{-9}\frac{C}{pulse}*\frac{1\ e-}{1.602*10^{-19}}=6.2422*10^{10}\frac{e-}{pulse}</math>

Using a distance of 25cm for all simulations following. 

===OSL===

<math>\frac{1}{1000}</math> of a pulse. ~62mil e- simulated, ~62bil e- per pulse. With beam parameters given above.

Deposited Energy: <math>4.46596*10^{6} 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>4.46596*10^{9} MeV</math>

Converting to Joules for dose calculation: <math>4.46596*10^{9} MeV=7.15525*10^{-4}J</math>

Average dose per pulse <math>\frac{7.15525*10^{-4}J}{0.0234777*10^{-3}\ Kg}=30.4768\ Gy=3047.68\ rad</math>

===Quartz===

<math>\frac{1}{1000}</math> of a pulse. ~62mil e- simulated, ~62bil e- per pulse. With beam parameters given above.

Deposited Energy: <math>4.71875*10^{8} MeV</math>

Quartz Geometry: 1 inch 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}*(2.54))*(2.32)=29.8593g</math>

Scaling deposited energy by 1000 to account for only shooting a 1000th of a pulse, the deposited energy becomes <math>4.71875*10^{11} MeV</math> 

Converting to Joules for dose calculation: <math>4.71875*10^{11} MeV=0.0756027J</math>

Average dose per pulse <math>\frac{0.0756027\ J}{29.8593*10^{-3}\ Kg}=2.53196\ Gy=253.196\ rad</math>
