Tracker Hardware commissioning

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

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

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

Tracker Validation

Downstream tracker; maximal fluence setting:- aim is to illuminate both trackers with as many muons as possible

Beamline Pre-Commissioning

To be defined.

Tracker External Alignment/External Alignment other detectors

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.

Validation of track matching

Muon beam, 3 momenta, scan Q789 for TOF0-1 matching?

Validation of PID

Pion beam, different momenta
Electron beam?

Beam-Based Alignment

Run with SSU, three momenta, 10k muons, fiddle with currents to get most fluence
Run with SSD, three momenta, 10k muons, fiddle with currents to get most fluence
Run with AFC, three momenta, 10k muons, fiddle with currents to get most fluence
Run with combined, 10k muons, in baseline optics setting, fiddle with currents to get most fluence

Beamline Commissioning

M1 Matrix elements?

Cooling channel optics validation

Few momentum settings, few beta function settings, 100k muons?
