	T.B. Petersen, J.S. Diamond, N. Liu, P.S. Prieto, D. Slimmer, A.C. Watts Fermilab, Batavia, Illinois, USA
	The readout electronics for the resonant beam position monitors (BPMs) in the Fermilab Switchyard (SY) have been upgraded, utilizing a low noise amplifier transition board and Fermilab designed digitizer boards. The stripline BPMs are estimated to have an average signal output of between -110 dBm and -80 dBm, with an esti-mated peak output of -70 dBm. The external resonant circuit is tuned to the SY machine frequency of 53.10348 MHz. Both the digitizer and transition boards have vari-able gain in order to accommodate the large dynamic range and irregularity of the resonant extraction spill. These BPMs will aid in auto-tuning of the SY beamline as well as enabling operators to monitor beam position through the spill.

TUPOA31	Fermilab Cryomodule Test Stand RF Interlock System	355
	T.B. Petersen, J.S. Diamond, D. McDowell, D.J. Nicklaus, P.S. Prieto, A. Semenov Fermilab, Batavia, Illinois, USA
	An interlock system has been designed for the Fermilab Cryomodule Test Stand (CMTS), a test bed for the cryomodules to be used in the upcoming Linac Coherent Light Source 2 (LCLS-II) project at SLAC. The interlock system features 8 independent subsystems, consisting of a superconducting RF cavity, a coupler, and solid state amplifier (SSA). Each system monitors several devices to detect fault conditions such as arcing in the waveguides or quenching of the SRF system. Additionally each system can detect fault conditions by monitoring the RF power seen at the cavity coupler through a directional coupler. In the event of a fault condition, each system is capable of removing RF signal to the amplifier (via a fast RF switch) as well as turning off SSA. Additionally, each input signal is available for remote viewing and recording via a Fermilab designed digitizer board.
