ECAL Electronics, DCS• T-MUX module
– multiplexing + transducer module (RBFE), has single channel transducer ASIC
– sensor excitation and raw signal conditioning for 8/16 sensors
– ASIC : has current source (1/10/100 A), diff. amplifier, Vref (2.5 V), control logic,
provides diff. voltage (0-2.5 V) output signal
– Sensor excitation via DC current, 1 or 10 A
– ASIC : developed for LHC cryogenics control, designed and tested for use in radiation
environment
• issue of radiation hard MUXs investigated at the moment
– Two technicians from Protvino have work together with LHC-ACR group on development
of this T-MUX module
– currently under test in ETH lab
• To be defined : – exact sensor location and fixation– installation sequence
