 h2. 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 

 h2. Tracker Validation 

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

 h2. Beamline Pre-Commissioning 

 To be defined.
