Alexa, Rich After dressing in all the in-vacuum cabling in HAM1, we took final RF transfer functions of all detectors at their respective operating frequencies. These transfer functions are taken from the ISC-R2 rack (patch panel connector for LSC detectors, and terminated cable ends for ASC Detectors. The cable (type LMR-195) has an RF loss of ~2.5dB per 100 feet and a velocity factor of 0.76. The cable length from rack (as measured by time domain reflectometer (TDR) is 43 feet to flange, 57 feet to detector). The in-vacuum cable is a flexible RG316 equivalent made by Gore Inc. The velocity factor is approximately 0.7 for this cable. The measured loss of this cable (done at CIT) on a 10.5 foot section is: 0.28dB at 9MHz 0.50dB at 36MHz 0.56dB at 50MHz 0.84dB at 100MHz All transfer functions taken from test input to RF outputs. Don't forget to enable the RF test switches for the LSC detectors, then disable them once you are done measuring to avoid an unnecessary noise introduction path into the LSC detection chain.
