The increasing industrial use of cryogens for fuel, refrigeration, and energy storage demands the development of advanced metrology to effectively design systems and accurately meter fluid transfer operations. However, the storage and transport of cryogens near saturation conditions frequently results in multiphase flow, precluding the use of existing single phase only cryogenic flow meters. ...
Most cryogenic regulating valves used in CERN cryogenic facilities rely on the Siemens Sipart™ intelligent valve actuator and for future deployment in the Large Hadron Collider (LHC) High Luminosity (HL-LHC) upgrade it is necessary to better understand the effects of particle radiation on the operation of these control valve actuators. When used in radiation environments, the Siemens™...
The need for superconducting magnets in high energy physics investigations currently drives much of the research and development in cryogenics. With collider energies and fusion reactors continuing to reach new levels, it’s necessary to constantly push the operating limits of supporting technologies. A crucial component in these experiments is the cryogenic temperature sensor used to monitor...
The helium cryogenic plant of the Comprehensive Research Facility for Fusion Technology (CRAFT) is equipped with four helium refrigerators, to meet the demands of testing superconducting magnets, conductors, and materials. A digital twin platform, Cryo-DT, has been developed based on the cryogenic plant control system. Cryo-DT uses the Experimental Physics and Industrial Control System...
The Cryomodules are critical components in the European Spallation Source (ESS) accelerator, playing a crucial role in connecting spoke cavities to high-beta elliptical cavities in the SRF Linac. These Cryomodules provide the necessary environment for operating, Spoke (Spk) cavities, Medium-Beta (MBL) and High-Beta (HBL) elliptical cavities, which are responsible for accelerating protons from...
We present a helium gas flow meter designed to measure power dissipation in Superconducting Radio Frequency (SRF) cavities by quantifying the evaporation rate of helium vapor. The meter operates in the 3–7 K temperature range, measuring helium flow rates with a resolution of 0.05 g/s (~1 W) and functioning at gas velocities from 1 to 14 m/s.

The traditional integration of Cryocooler Control Electronics (CCE) into spacecraft is evolving. Iris Technology’s continual growth and development of pre-integration methods for CCEs with cryocoolers will further reduce the complexity from the larger spacecraft system integration. Enhancements have been made to the system integration process, including an automation feature for...
Fermilab has a project to improve the proton beam energy which is called PIP-II (the 2nd Proton Improvement Plan). There is a superconducting linear accelerator, LINAC, to improve the proton beam power and the LINAC consists of 5 types of cryomodules (CM), 1 HWR CM, 2 SSR1 CM, 4 SSR2 CM, LB650 CM, and HB650 CM. The prototypes of these cryomodules are being tested at Fermilab’s CryoModule Test...
CRAFT is a fusion reactor research facility initiated by the Institute of Plasma Physics, Chinese Academy of Sciences, as part of the national scientific strategy. CRAFT 6kW helium refrigerator is used to provide 4.5K cryogenic test environment for superconducting magents.The EPICS (Experimental Physics and Industry Control System) architecture allows direct access to the PLC controller via...
