1. Activity: TDR: * Range System Prototype is on the way to CERN
G.Alexeev, GSI, 13 December 2011 Dubna Group Activity Report & Update on TDR
Activity:
* Range System Prototype is on the way to CERN
* Studies of strip signal readout of 1x1 m2 detecting plane
(that of RSP) conducted with Co-60 and cosmic demonstrate
its feasibility (see report of A.Piskun)
* Full Size Prototype (2x4 m2) at CERN/COMPASS is operational now
* MC studies of calorimetric features of Range System is in
progress (see preliminary results in report of V.Rodionov)
* Digital R/O electronics for 4600 channels of RSP is ordered/paid
TDR:
* Chapter on long strip signal readout is added -> mandatory for two-
coordinate detector !
* Chapter on influence of “zero bi-layer” on Muon System acceptance
is added

2. Lorry in DNLP/JINR Lab during the loading of Range System Prototype equipment

3. Boarding of Range System Structure

4. All RS Prototype equipment on board
RS Structure
Box with FEE
Box with MDTs
Box with strip boards, LV supplies and electronic equipment

5. On the way to CERN from Dubna
The departure date from Dubna was December 7th
Expected arrival to CERN is December 15th

6. Full Scale (2 x 4 m2) prototype in work position at CERN/COMPASS
Full Scale Prototype (2x4 m2) at CERN/COMPASS: put in operation, runs smoothly at high muon halo flux (~10 kHz/cm2), wire signals are observed

7. Wire signal (up) and 2m long strip “signal” (down) as seen on scope at ~ 40 m from setup – the frequency of COMPASS DAQ (~ 40 MHz) is peaked up by readout

8. Attempt of Nikolay Zhuravlev to cure the noise problem in strip r/o channel…

9. Attempt was successful –> excellent wire signals, but no strip signals due to the mistake in cabling !

10. Plans for 2012 (preliminary -> depend on budget):
* Finish/approve Muon System TDR
* Full Scale Prototype - continue study of long (2-4 m) strip signals readout
* Range System Prototype – assemble, commission with cosmic, put in operation
on PS/CERN test beam
* Continue studies of MDTs on the Lab test stand – wire and strip readout
* Software development – in cooperation with Torino/INFN group

11. PANDA-Wikipedia (with muon comments):
… The giant PANDA is an endangered species, threatened by continued habitat loss and by a very low birthrate …
( we are here to solve exactly these problems )
… Giant PANDA reaches … maturity between the ages of four and eight …
( we are with PANDA around eight years, so feel matured enough to act )
… The giant PANDA typically lives around 20 years in the wild and up to 30 years in captivity…
( good prospects ! )
It looks like this PANDA got funding…
And we also hope for that!
