Dalian Advanced Light Source (DALS), located at Dalian, China, aims to construct a new light source that can generate high brightness X-Ray pulses. The DALS, which consists of 12 cryomodules, based on the Superconducting Radio Frequency (SRF) technology for the linear accelerator operating in continuous wave. Before the construction of the DALS, a series of test facilities, including vertical...
The purpose of the Dalian Advanced Light Source (DALS) Test Facility project is to test core components of DALS accelerators, such as cryomodules and superconducting cavities. The project includes a horizontal testbench (HTB) for cryomodule test, a vertical testbench (VTB) for superconducting cavity test, and an injector testbench (ITB) for beam test. The cryogenic system of the test facility...
The Dalian Advanced Light Source (DALS) test facility has developed a vertical test cryostat to measure the quality factor and accelerating gradient of SRF cavities at a nominal temperature of 2 K. The cryostat employs a dedicated insert that can accommodate four cavities simultaneously. A built-in phase separator of the cryostat aims to pre-cool the supply helium and further facilitates the...
In 2023 Criotec Impianti Srl was awarded the CERN contract covering the design, manufacturing, and installation of the cryogenic system for the Neutrino Platform Dark Side-20k proximity cryogenics.
The DarkSide-20k experiment consists of an inner detector housed within a sealed stainless steel vessel and an outer muon veto, deployed within a ProtoDUNE-style membrane cryostat. It is currently...
Purification of the process gas is vital for reliable operation of cryogenic systems. For helium cryogenic systems operating at 4.5 K or below, this is critical as any matter other than the process gas (helium) will freeze and act as a solid contaminant. Persistent low-level contamination (mainly the constituents of air and moisture) at levels greater than 1.0 ppmv, will degrade the...
