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)

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

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)
