Superfluid helium is another phase of liquid helium when it is cooled below 2.17 K, under saturation condition. The superfluid helium bath cools the niobium superconducting radio frequency (SRF) cavities housed in the helium tanks of the cryomodules. The SRF cavities operate at temperatures of 2.0 K or below, due to its higher operating frequency like 1.3 GHz. At KEK, the superfluid helium...
Over 20 years more than 25 superconducting multipole insertion devices for generation of synchrotron radiation (wigglers and undulators) have been created at BINP for several synchrotron radiation centers. It was developed a cryogenic system based on cryocoolers which allows autonomous operation of superconducting insertion devices on the storage ring without maintenance and consumption of...
The SC dipole magnet for the CBM detector consists of 150 tons mass of iron yoke, SC magnet of 5 MJ of stored energy, cryogenics adopted to the FAIR local conditions. The magnetic field in the center of the detector is ~ 1 T, on the coils is ~ 3.7 T. The superconducting cable having unique parameters was manufactured and tested. The dipole coils will be indirectly cooled by 4.5 K helium in...
BINP presents the design and production of the 2T cryogenic solenoid for the PANDA detector at FAIR.
High Energy Photon Source (HEPS) is the first high-energy ring-based synchrotron radiation light source in China. The HEPS is designed with a beam energy of 6GeV and an ultra-low emittance of better than 0.06nm.rad to provide high-energy, high brightness hard X-rays. In phase I for the HEPS 15 public beamlines and corresponding experimental stations will be constructed by Institute of High...
SHINE, the Shanghai HIgh repetitioN rate XFEL and Extreme light facility, a quasi-continuous wave hard X-ray free electron laser facility, is currently under construction. The SHINE cryogenic system is divided into three groups, the test facility cryogenic system, the accelerator cryogenic system and undulator cryogenic system. Among the three cryogenic system, the test facility cryogenic...
Platform of Advanced Photon Source Technology R&D (PAPS) was officially launched in Beijing Huairou Science City in Feb. 2017. The goal of the PAPS project is to provide a good foundation and condition for R&D, engineering testing and verification for the high energy phone source (HEPS), especially the R&D of different SRF cavities for the future scientific project. The cryogenic test facility...
Vertical Test Stand (VTS) and Horizontal Test Stand (HTS) Facilities are set-up at RRCAT for testing and qualification of Superconducting Radio Frequency (SCRF) Cavities. VTS facility is operational since 2013 and tested many single cell and multi-cell 1.3 GHz and 650 MHz cavities at 2 Kelvin. HTS is in its commissioning trials. HTS cryostat designed for cooling down two 650 MHz dressed SCRF...
3W1 SC wiggler with the pole gap of 68 mm have been successfully tested and installed in the BEPC II storage ring in November 2019. The goal of zero liquid helium consumption is achieved, and the residual cooling capacity of cryogenic system is about 0.69 Watt @4.2 K, equivalent to 12% of total cooling capacity of cryogenic system. The 2.6 Tesla magnetic field has been achieved and 3W1-SCW...
