Dear pandaRooters,

I have added two new geometry files, one for the solenoid (without the Muon chambers) and one for the MVD.

Cheers,

Tobias

Hi Tobias,
I have tried to use your Solenoid.root file as input for the magnet geometry, and I get the following error:

Or better, it is a warning but after the program exits.
Maybe there are some problems with the media?

Hi Stefano,

it is nice to see that somebody uses the things one does Smile.

I have updated the geometry in SVN and fixed the problem with the solenoid coils.

Ciao,

Tobias

Thanks a lot,
but now I have the following:

---
Material aluminium is not defined
Create Medium aluminium
-W- WARNING in CbmModule::ExpandNode()! The volume BarrelYoke710 Has no
medium information.

(maybe we can talk via skype or evo, so that we can crosscheck all the small fixes).

Hi,
I have seen that if I run the MVD macro macro/mvd/runMvdSim.C (I have tried only 100 events) with the old geometry MVD14.root everything runs fine.

If I substitute the geometry namefile with the new one MVD_1.0_Pv-1.0_Sv-1.0.root, under Geant3 the macro runs fine as well.
But, when I try to quit ROOT with the .q command I have the following error (backtraced with gdb):

Toggle Spoiler


If I run it under Geant4, I have the following error just at the beginning, in the initialization of the geometry:

Toggle Spoiler


So maybe something is wrong somewhere.

Hi Stefano and Ralf,

I have updated the geometry of the MVD in the latest revision. The new root file does not contain a GeoManager as it is in the old root file. Maybe this is the reason for the strange behaviour of Geant4?

Ciao,

Tobias

Hi Tobias,
unfortunately now I have errors even with Geant3 in the event loop, after the first event:

Toggle Spoiler


In Geant4 the geometry initialization works, but I have the same G3 error inside the event loop after the first event:

Toggle Spoiler


So there is still something wrong.

Hi Tobias and Stefano,

I cut out the volumes by hand from the file with the TGeoManager inside and I get the same errors as Stefano.
Somehow this doesn't work like this.
I noticed that there are many TDirectories in the file with the GeoManager, like two directories with materials and one even with transformations. Could this lead to confusions? Maybe to overlaps?

Ralf.

Dear pandaRooters,

I have fixed the geometry file for the MVD. It runs now (at my system) with the standard MVD simulation macro. The name of the Geometry is MVD_v1.0.root.

Cheers,

Tobias

Hi Tobias,
thanks for the fix. Now it can be downloaded with both G3 and G4, without crashes.

P.S. What was the problem?

I have used a geometry which could not be translated. This should not create a problem but nonetheless it did. So I just deleted these structures out of the STEP file. I will now try to understand, why they caused this crash.

Ciao,

Tobias

Hi,
if you want to use the last MVD geometry for the data challenge, please write "yes" here as soon as possible.

Please be careful about the digitization. It should work on the updated geometry, but one new feature are the trapezoid strip sensors in the forward disks.
Using the parameters as they are now it should work, but I have not checked it yet.

If you plan to only run the Geant simulation without digi&reco, then you'll get a definate "yes" fom me, too.

Ralf.

We plan to run complete reco, so it is better to use for the moment the old stuff.
We do not have the time to recheck everything right now.

Ralf is right, for the digitization and reconstruction I have to modify the hardcoded pixel dimensions and chip sizes.

This will take till Monday because I am today not in the institute.
The program should not crash but the results for the digitization have to be fixed afterwards if this is not done.

Another fix which is necessary is to set the right name for the sensitive volumes in PndMvdDetector. There one has to add "StripActive" and "PixelActive" to the list of sensitive volumes in the constructor. Ralf, can you fix this?

Cheers and a nice weekend

Tobias

Dear all,
after some debugging done by Tobias (I was his "Guinea pig"...), now the geometry of the solenoid is working, the file is FullSolenoid.root.

Considering that this is just the solenoid part, I have added inside the geometry directory a file dipole.geo with only the dipole part.

In order to use these files you have to substitute your "magnet" part in your simulation macro with the following code lines:

CbmModule *Magnet= new PndMagnet("MAGNET");
Magnet->SetGeometryFileName("FullSolenoid.root");
fRun->AddModule(Magnet);

CbmModule *Dipole= new PndMagnet("MAGNET");
Dipole->SetGeometryFileName("dipole.geo");
fRun->AddModule(Dipole);

And this will be the result, with all the detectors:

Toggle Spoiler


As you can see there is an overlap between the old target pipe and the new solenoid, in order to solve this we need drawings of the new pipe, but at the moment this is not of fundamental importance.

Thanks to Tobias for the time he spent into this geometry conversion.
