This study presents a brief overview of the 1st and 2nd phases and an in-depth analysis of the 3rd phase heat load testing performed on the pHB650 (prototype High Beta 650 MHz) cryomodule at PIP2IT (PIP-II Injector Test Facility), with a focus on both the results and the methodological advancements that have improved testing efficiency and accuracy. A key challenge identified in the testing...
Superconducting undulators have become a research hotspot of the insertion devices in the synchrotron radiation facility. However, the cryostat, which is used to create a liquid helium temperature environment, often causes the failure of the superconducting undulator. In this work, a cryostat with a new refrigeration distribution for a superconducting undulator is designed, fabricated and...
Conduction cooled HTS magnet have been developed due to their easy operation and compact size. REBCO coated conductors are widely used for the HTS power application, high magnetic field magnet application, and etc.. The thermal stability of the REBCO conductor is essential for the operation of HTS-based device, and thermal conductivities of the conductor are relevant parameters for modeling...
Dalian Advanced Light source (DALS) test facility project is primarily responsible for the performance test of DALS accelerator cryomodules and superconducting cavities. Accurate measurement of the Q0 of superconducting cavities relies on precise heat load measurements, including the static heat load of the cryomodule and the dynamic heat load during cavity operation. The DALS horizontal...
MRI ( Magnetic Resonance Imaging) is a non-invasive medical imaging technique that uses strong magnetic fields to produce detailed images of the body's. which is generated by the superconducting magnet generates typical at low field, 1.5T, 3T, and 7T (typical for ultra-high field) in clinical practice. The traditional magnet is cooled by liquid helium, with safety features including gas...
A Compact 7 T ultra-high field and fully sealed low cryogen Magnetic Resonance Imaging (MRI) system has been developed at the GE HealthCare Technology & Innovation Center, Niskayuna, USA. The cold mass (magnet) has been cooled down to 4 K using only 12 liters of liquid helium liquified with three SHI GM type RDE-412 two-stage cryocoolers. A gas tank has been charged to 150 bar with pure helium...
