Topics
Removing Mott scattering chamber
Time of flight results
Valeri Tioukine's Mott analysis
Beam Time
* Beam time for each target using S0 (assume no dependence of Sherman function on target thickness) and no limit on DAQ rate. Gold (Au, Z=79), Silver (Ag, Z=47), Copper (Cu, Z=29). Note that: Figure of Merit (fom) ~ sigma * S^2 ~ Z^4. Beam Time ~ 1/fom = 1/Z^4
* Beam Time for Gold with target thickness correction and DAQ rate < 5000 Hz.
* Beam Time for Silver with target thickness correction using Gold extrapolation and DAQ rate < 5000 Hz.
* Beam Time for Copper with target thickness correction using Gold extrapolation and DAQ rate < 5000 Hz.
* Note: Target thickness extrapolation used above:
- Alpha as a function of Kinetic Energy: alpha = 0.0066 + 0.052 * kine
- Effective Sherman Function: eff_sf = S0 /(1.0 + alpha * d)
