Summary

During the last years, temperature monitors from Lake Shore are mostly known in many cryogenic laboratories and organizations. For example the “LS 218” monitor is the main instrument for the FAIR SIS100 magnet prototype testing at the GSI in Darmstadt. The demands for the SIS100 accelerator system include immunity against harsh electromagnetic radiation and low radiation dose for long life time. Usually instrumentation modules for low temperatures regimes are very expensive and require high skill specialists for implementation of calibration curves for temperature sensors. For satellite helium refrigerators the ILK developed reliable instrumentation modules for low temperature measurements with cold multiplexers. Based on these instruments a new temperature monitor has been designed which fulfils the GSI specifications. Beside this, the universal “plug & play“ temperature monitor from ILK brings new features like: SD card for reading of calibration curves and recording of data, long time offline battery operation, efficient suppressing of electromagnetic noise and high channel count with optional cold multiplexer. First metrology comparison tests of both LS 218 and monitors of ILK, performed by the GSI, showed a better performance of the ILK design. Specialists at the GSI are testing and evaluating the ILK units for the open market. This new developed ILK temperature monitors, their test results and specifications will be presented and discussed in this paper.
