There are some unique challenges when having to monitor temperatures of superconducting magnets in high-energy accelerator facilities. Scientists require sensors with resolution high enough to detect small temperature changes plus fast thermal response times to detect potential superconducting magnet quenches. The thermometers must also offer magnetic field insensitivity, radiation hardness, and good long-term stability over the lifetime of the accelerator.
Lake Shore Cernox™ resistance temperature sensors were specifically designed for the purpose of monitoring superconducting magnets in high-energy accelerators and meet the criteria required for this application. To read more about what led to the development and commercialization of our Cernox™ sensors for high-energy physics and how they compare with other sensor types, read this new paper authored by Dr. Scott Courts, Lake Shore Applications Scientist. It summarizes how Cernox™ sensors are fabricated, packaged, and calibrated for accuracy, and details the performance characteristics of the sensors relative to their use in high-energy physics accelerator applications.
If you are going to the CEC/ICMC conference next month in Tucson, AZ, Dr. Courts will be teaching a short course on Sunday, June 28, the day before the actual conference begins. His four-hour “Practical Thermometry and Instrumentation” presentation provides a practical look at the technology needed to perform accurate cryogenic temperature measurement. Sign up for the course.
