h2. Tracker Hardware commissioning
14 3 Rogers, Chris
15
Upstream tracker; maximal fluence setting:- aim is to get as many particles as possible through the tracker centre, choose muons because they don't decay. No diffuser, low emittance beamline
16
17
Upstream tracker; maximal illumination setting:- aim is to illuminate the upstream tracker reasonably evenly, choose muons because they don't readily decay. High emittance beamline
18
19
Downstream tracker; maximal fluence setting:- we will illuminate the entire downstream tracker no matter what, so here we want to just get the best rate through that we possibly can

21
h2. Tracker Validation
22
23 5 Rogers, Chris
Downstream tracker; maximal fluence setting:- aim is to illuminate both trackers with as many muons as possible
24 6 Rogers, Chris

29 7 Rogers, Chris
h2. Tracker External Alignment/External Alignment other detectors
30
31
Downstream tracker; maximal fluence setting:- aim is to illuminate both trackers with as many muons as possible. Take a setting at 140, 200, 240 MeV/c to try to fight residual fields systematic.

Run with SSU, three momenta, 10k muons, fiddle with currents to get most fluence
45
Run with SSD, three momenta, 10k muons, fiddle with currents to get most fluence
