Hello,
I have committed in svn the last version of the muon detector geometry (done by George), including also the muon filter.
Inside the code there are also the classes to create the return yoke and the absorber, considering that the actual version of the solenoid is not working.

The following is the plot of the geometry:

index.php?t=getfile&id=5543&private=0

You can see the hole for the target pipe, and the additional muon filter. DCH geometry should be tested, to see if it fits inside the muon fitler (the size is taken from integration design ver. 0.1.15 (2009-06-05)).
In macro/mdt you can find the sim_muo.C macro to use that geometry (waiting that the solenoid is ready).

Regards

Hi

Nice view of muon detector geometry, but

the real muon system geometry is different and more complicated.

Dear Valery,

....then the question will be "How the real muon geometry should look like"?!?

Greetings,

Johan.

The "Torino" design implemented in PandaRoot consists on sensible planes placed at the official positions, for tracking studies (which I am doing) and physics analysis about background rejection.
The "Dubna" design is the same (in general terms) but has a high level of details (box/tube/wire). At the moment there are no "ProcessHits" or other functions for simulation inside PandaRoot and digitization, only geometry root file.

Hi Johan

at the end of July 2009 A.Efremov put an revised magnet version on
PANDA Wiki -> Magnet -> Internal. Our model are in according to this final (I hope) magnet version. In pandaroot we have an oldest magnet version (PandaSolenoidV833.root). So we are waiting for the new magnet revision.

The muon system files are:
muon_FS.root -> Forward System (MDT + Fe)
muon_TS_barrel.root -> Yoke: barrel part
muon_TS_endcap.root -> Yoke: endcap part

Up to now theri is no geometry file for Muon Filter. We are waiting for drawing from DC side hole in plate).

For this reason, in the Torino design, the magnet version we are using is constructed inside the MDT classes, so that one can have the correct amount of iron without using the old-fashioned solenoid.
Still the coils are missing within this design, I hope Tobias can convert just them, in order to have almost everything running.
