Overview

• In total, the CMS Pixels would like to have
• 3 Siemens S7-300 Systems
• 1 installed at P5
• to be used by BPix FPix for the Engineering Run
  
• and final Detectors
• 1 installed at TIF
• to be used by FPix for Commissioning at CERN
• 1 installed at SiDet
• to be used by FPix for Commissioning at Fermilab

Remarks on P5 System

• The P5 System consists of
• 2 Relay
• 1 Digital Input
• 1 Analog Input
• 32 RTD
• Modules
• The Modules are mounted on 5 Rails,
• hosted in a CERN 19 Rack

Remarks on Cabling

• Rail 1
• Relay
• Digital Input
• Modules connected via Terminal Blocks
• Analog Input
• Module can be connected as for SiTracker
• Rails 2 5
• RTD
• Modules can be connected in a modular way
• A Pair of 2 RTD Modules gets Input from 1
  (72-wire) Field Cable,
• Connected via a 78-pin SubD Connector
• From the 72 wires, 4 wires need to be feed
• into the HMX Conditioning Board.
• We propose 4-pin Burndy connectors for this
  purpose.

TIF and SiDet Systems

Remarks on TIF/SiDet System

• The TIF/SiDet systems are foreseen for
  Commissioning
• of individual FPix Half-Cylinders
• (one Quarter of the whole FPix Detector)
• Because only a Quarter of the FPix Detector (and
  no BPix) needs to be
• controlled at a time, less RTD modules are needed
  for Detector Control
• than in the P5 system.
• On the other hand, 2 additional RTD modules plus
  2 Analog Input modules
• are needed to control the Cooling-Box that keeps
  the Half-Cylinders at -10oC
• during Commissioning.
• So, the TiF/SiDet Systems consist of
• 1 Relay
• 3 Analog Input
• 6 RTD
• Modules
• The Modules are mounted on 2 Rails
