- Request #2. We measured dependence of the physics asymmetry on the position of the beam on the target foil from two target foils: 0.225um and 1um. For each foil we measured 7 asymmetries (one at center and six others away from center). The details are described in the systematics TN on the wiki. He'd like a plot showing the measured physics asymmetries (weighted average of IN/OUT) vs. radial distance from the center (instead of using x/y values shown in the TN), and then the average with it's uncertainty band, for the two target foils.
- Asymmetry vs Beam Position from Nominal (radially)
- Request #3 - Recreate Michael's Paper's Plot
- Remaking of Figure 6: media:Au_targetMSteigerwald.gif. The lines are a fit ( asym = a / (1.0 + alpha . d) ). On the original figure, the lines were his calculations.
- Asymmetry vs Deadtime/Beam Current
- Request #1. We measured dependence of electronic dead time on the beam current at five different average beam currents from 0.245-4.1 uA on a 1um foil. He'd like a plot showing the five data points vs. beam current with their individual uncertainties, and then the average with it's uncertainty band.
