---+ *Services*

---++ Electrical services

The elecrical services have been re-desgned to take the data off the ring tape and to include DCS.

This includes a re-design of the hybrid and the EOSCs.

Material used for these items are located at [[2016ElectricalServices]]

---+++++ 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):

---+++++ 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.

---+++++ Cooling

Some information on the [[CO2cooling]] here

---+ *Integration*

Some STEP files (created in Inventor) from Fred Gannaway:
   * [[%ATTACHURL%/Pixel_Ring_Endcap_Side.stp][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.
   * [[%ATTACHURL%/Pixel_Discs.stp][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.

---+ *Characterisation of transmission lines*

Passive electrical components, such as bus tapes, cables and transmission lines can impact signal quality. A common method of studying the signal degradation is by measuring S-Parameters. S-Parameters can be shown as a transmission vs frequency plot or can be used as inputs to many simulation programs for more advanced studies. Two different test procedures for measuring S-parameters are available at the links below. The RAL method uses an older TDR instrument. The Glasgow method uses a newer network analyser.
