Hi again,



Looking a little further it seems like the inner radius of the EC Ecal (now 38cm) and the EC Hcal (now 39cm) must be increased to match the EC Muon System/return yoke at r_min=53cm.

See figure:

Hi Hans,



In reviewing the compact.xml file I see that no space has been defined for the coil package to produce the 5T field.



In SiD the package is 82.5cm thick with an ID of 5.2m. It sits in a reserved volume of 82.8cm.



For MCD, the # amp-turns will need to scale by the area ratio: (6/5.2)^2=1.33.

I am informed that the #strands of SC cable (40) in the CMS coil package is maxed out so you will need 33% more turns; the coil cannot carry more current.

I believe there are 6 layers of coil in the SiD design at 60mm each, so to a first approximation the coil package width will grow by 120mm to 94.5cm in say a 95cm gap.



Tom

Hi







attached you find the tar file with the new muon collider detector data.

Changes are:



- tracker layout as sent out by Ron Lipton last week.

- since the tracker is bigger the tracking region is increased and the

calorimeter are moved

   to higher radius.

- I fixed a bug modeling the borated polyethylene layer that Nikolai

Terentiev pointed out to me.



have a look at the compact.xml file  as it's the easiest file to read

and let me know if things look ok.



The files are all in the LCDetectors CVS repository. I am now simulating

Higgs events with the latest version of slic available on mcdrd.

I will send mail when the files are available.





cheers Hans
