Cabling, power supply modules

The existing cables for the standard Hall-C spectrometers (HMS and SOS) will be used for the signal cables for the ENGE, HKS detectors, though some of them are broken and repair work is necessary. The HV cables exist from G0 patch in Hall C to the 2nd floor of the counting house. The HV crates on the 2nd floor can be used for us.

Table 19 summarizes the number of requires BNC/HV cables and table 20 does the existing cables.

For HKS and Enge drift chambers, low voltage high current power supplies are necessary (section 6.3). Acopian DC power supplies are used for SOS and they will also work for HKS and Enge. Low current, low voltage, but adjustable voltage power supplies are needed for threshold setting of N277 amp-discriminator cards.
