The new 240 Series offers a convenient, modular input solution for precision monitoring of cryogenic temperature sensors in large-scale applications employing distributed PLC-based control.
Lake Shore benchtop cryogenic instruments are trusted throughout the world for precision temperature measurement—now that same measurement performance can be achieved in widely distributed high energy applications like particle accelerators and fusion reactors as well as other large industrial sites.
The smaller package size of these thin film sensors makes them useful in a broader range of experimental mounting schemes, and they are also available in a chip form.

The cryogenic temperature sensing requirements of superconducting magnets used in high energy physics accelerators present a unique challenge. The sensors must operate at cryogenic temperatures below 4.2 K with low magnetic field- induced calibration offsets at fields ranging to 10 T. They must provide high resolution with fast response times to detect potential superconducting magnet quenches. The sensors must be stable over time and thermal cycling with low radiation-induced calibration offsets up the anticipated accumulated dose over the lifetime of the accelerator.
Cernox® thin film resistance cryogenic temperature sensors offer significant advantages over comparable bulk or thick film resistance sensors
This combination of unique requirements severely limits temperature sensor choices for monitoring superconducting magnets. Cernox™ resistance temperature sensors, manufactured by Lake Shore Cryotronics, Inc., were specifically designed and developed for the purpose of monitoring superconducting magnets used in high energy accelerator facilities and meet the criteria required for this application. This work details performance specifications for Cernox resistance temperature sensors with regard to their suitability for high energy physics applications.
