MagnetScan

Magnet scan for rescattering and poletip.

Rescattering

Integrating mode 2 uA (to be safe) on Lead Adjust HV to get a good signal for 2 uA Compare signal on-detector for new HV to normal HV Detune spectrometer up in momentum. 1%, 2%, 4%, 7%, 10%, 15%, 20%, 25% Note, Jack said the septum could go up but wasn't sure how high. The septum power supply may limit us.

A scan down may be considered. Motivation is for poletip scattering and just in general to understand the HRS. Same conditions as above. -1%, -2%, -4%, -7%, -10% (negative)

Poletip Scan

Start with all magnets at tune P (nominal). Counting mode. 20 nA on Lead

Q2 scan +/- 2%, 5%, 10%

Septum scan: +/- 5%, 10%, 15%

Later to have a Geant4 model to try to understand these scans.
