Development of FPGA-based multi-sensor excitation low voltage (MSELV) chassis at Jefferson Lab.

The design and development of the sensor excitation and read back chassis was driven by the requirements for the monitoring and control of two conduction-cooled superconducting magnets in Hall B for the 12 GeV accelerator upgrade. The torus and solenoid superconducting magnets require extensive instrumentation. Sensor selection was accomplished by applying Jefferson Lab's (JLab) risk mitigation process, which employed a failure modes and effects analysis approach.
