1. G.Alexeev for Dubna group ITEP, April 28, 2010 Muon System Status Report from Dubna
Hardware :
* Full Scale prototype - in preparation to be put in work position at COMPASS,
expected start of long strips r/o studies – May-June 2010
* Range System prototype (degree of readiness) :
- steel absorber /structure ~ 95% (Fe plates 100% ready -> to be welded)
- MDT detectors ~ 50 % (all parts 100% ready, 10% of MDTs assembled)
- strip boards, cables ~ few % (to be produced by summer 2010)
- f/e electronics ~ few % (design 100% ready, mass production required)
( see report of A.Piskun)
Software :
* Acceptance studies for DY and J/ muon pairs (see report of V.Rodionov)

2. Full Scale prototype mechanically assembled and stored in COMPASS area (park position) It is now being equipped with HV,LV, gas lines, strip boards, f/e electronics and tested before the start of COMPASS run

3. Full Scale prototype position in COMPASS area. The prototype
should be fixed
at this point in
May 2010

8. Geometrical acceptance study of muon system in case of:
full PANDA setup (material)
Pythia as event generator (40K DY events) + PandaRoot.
Option: with/without magnetic field in Solenoid/Dipole.
Polar angle distribution of DY photons.

9. Plans for 2010:
* FS prototype :
- finish full assembly (HV, LV, cabling, gas lines, f/e electronics etc)
- start running (r/o test with long 2-4 m strips) in summer 2010
- study of wave impedance for strip r/o
* RS prototype :
- finish production (300 MDTs, absorber structure, strip boards, cables etc)
- produce and test f/e electronics (292 boards of different types)
- move to CERN
- assemble (at COMPASS) and test with cosmic (debugging)
- start running in late autumn 2010 at PS (subject to available resources)
* Software development in PANDAroot :
- finish acceptance studies for muons (DY, J/ , D-mesons) with high statistics
- track finding algorithms for muons in Range System (together with Torino/INFN group)
- pattern recognition algorithms – muons vs hadrons (together with Torino/INFN group)
