EoS / GBTX

Graham Beck's work on putting an EoS card into the thermal FEA for barrel stave work. This includes photos of, and some technical information about, the EoS card and GBTX chips.

Integration

Some STEP files (created in Inventor) from Fred Gannaway:

• Pixel_Ring_Endcap_Side.stp The Pixel Ring Endcap Side is more mature and shows an option to mount each ring to the support tubes, it also includes four Carbon post stuctures to link the inner and outer tubes in an aid to transfer insertion forces and not subject the rings to any such forces. The model has several routings for cooling tubes which may all show up, you will have to suppress each option.
• Pixel_Discs.stp The Pixel_Discs model shows the array of the NP49 sectors inside the same inner and outer tubes, but without yet any fixation for these. The number of cooling tubes in this option is a concern but at the moment we do not know if we will have sufficient power to cool the ring design.

Bus Tapes

The bus tape design from the pixel barrel is being adapted for disks by Yiorgos Sidiropoulos at Edinburgh. Details can be found in this presentation (in two parts, to beat twiki's 20MB upload limit):
