40 K Shield Sensor Layout The 40 K shield is cooled from one side

40 K Shield Sensor Layout The 40 K shield is cooled from one side only. Therefore many sensors (CLTSs with several PT 100 s for calibration) will be used to verify that this approach works. 40 K Shield Support Sensor Input Coupler • The use of PT 100 s will also be explored. PT 100 devices have uniform resistance from batch to batch. It may be possible to use these in place of CLTSs. Peter Quigley Internal Design Review 9/5/2012
