TOB Rod System Tests at CERN

• TOB System Test Setups at CERN

  The TOB lab at CERN is placed in Build. 598 (find it here) and consists of a:

  • Single Module Test Setup
    An operational single module test setup (based on a UTRI card and a CCU6 chip)  and a data acquisition system equipped with a dedicated PC Linux computer with 1 TSC card, 1 FEC card, and 1 PMC-FED card. The system is intended for module test performance prior to their insertion into Rods.

  • Rod Test Setup

    • Single-sided Rod prototype (with CCU6 chip and 6 old LLD1 analog optohybrids) equipped with 6 TOB modules (which were used on past beam tests). The Rod has being electrically tested. A cooling plant C₆F₁₄ chiller is connected to the Rod and a full thermal cycle test has been performed to measure the cooling performance of the system. A total of 20 thermistor probes and 6 humidity sensors have all been placed in the Rod and readout with a dedicated PC slow controls computer. The system includes a dedicated PC Linux computer with 1 TSC card, 1 FEC card, and 3 PMC-FED cards.

    • January 2003 ----> First double-sided Rod
      This is a brand new final double-sided Rod (with CCU25 and 12 new Vienna LLD2 analog optohybrids) equipped with 12 TOB modules built at FNAL.

  Both systems include independently low voltage and high voltage power supplies. The readout devices (Rods and single module setup) have all being tested under bias voltage. A beta source setup has also been implemented and performance with external triggers is presently being studied.
