Agenda¶

Ryan, Stefania

ACTION: Improving TRACKER Geometry description - fibres outside fiducial region (Heidt)
- STANDS
ACTION: Victoria Blackmore to implement magnet field map interface (Victoria)
- STANDS
ACTION: Ruslan to provide relation between survey points and centre (?) first EMR plane
- STANDS
ACTION: RYAN to provide interface to fit for best detector positions, given survey points, to place all volumes.
- DONE - Needs detector responsible sign off on relation between survey nests and detector
ACTION: Ryan to udpate MAUS USER GUIDE
- IN PROGRESS
ACTION: Ryan to investigate how to reduce geometry load-time
- IN PROGRESS - Provisional success for geometries without overlapping volumes.
ACTION: PRY plates to be incorporated in TOF1, TOF2 shielding for STEP IV (JASON). This replaces the TOF cages which should not be used.
- STANDS (additional shielding may be needed for TOF1)

Ryan wrote translation algorithm to avoid manipulation. This is a script which takes Jason files, divided by material definition, and groups them in position-derived modules. Code in MAUS that translates Jason files to files to be used by GDML parser. Testing it now.
Three new geometries to CDB:1. Step I without EMR; EMR run; Step IV with tracker repositioned.
Problem of placing magnetic field wrt to magnet material: problem of bridging the gap between the magnetic field maps coordinate system and hall coordinate system; problem of setting it up in an automatic way to avoid human intervention.
Problem of alignment and geometry: shall we have a new geometry for each alignment configuration? Probably not. To be discussed with Chris Rogers.
Priority: get new geometry with GDML parser implementation to work
