Wed-Or7: Large Scale Cryogenic Systems 3
- John Weisend (ESS)
The Einstein Telescope (ET) is a third-generation gravitational wave detector planned in Europe, combining a low-frequency (LF) and a high-frequency (HF) laser interferometer. To exploit the full scientific potential of ET, cryogenic operation of the ET-LF core optics is crucial to suppress the fundamental suspension thermal noise, which dominates the detection sensitivity at low frequency, to...
The Dalian Advanced Light Source (DALS), proposed by the Dalian Institute of Chemical Physics (DICP), Chinese Academy of Science, Dalian, China, is a new Free Electron Laser (FEL) project based on superconducting radio frequency (SRF) cavity technology. Testing the Q0 performance of the cavity and measuring the static and dynamic cryogenic heat loads of the cryomodule (CM) are an essential...
Comprehensive Research Facility for Fusion Technology (CRAFT) was one of the Chinese big science and technology facility. The objectives were to explore and master fusion DEMO level key technologies for next magnetic confinement fusion. In order to test the performance of superconducting magnet, a large-scale helium refrigeration system was proposed and under construction. In this paper, the...
Fusion is one of the most promising options for generating the cleaner energy the world badly needs. Recent milestones in fusion include the new JET3 world record of generating 69 megajoules of fusion energy for five seconds by feeding two milligrams of deuterium and tritium. This is enough to power 12,000 households for about the same period. Delivering fusion energy to the grid is a...
Quantum computing has recently gained interest from industry, opening new fields of applications. Air Liquide Advanced Technologies, thanks to its experiences on ultra-low temperature systems (CryoConcept, subsidiary has been commercializing Dilution Fridges for 20 years for scientific labs) and on Helium Refrigeration and Liquefaction systems for Physics and Industry, is actively developing...
CUORE is the world's largest bolometric experiment, featuring a detector comprised of 988 TeO2 crystals with a total mass exceeding 740 kg. Since 2017, CUORE has been collecting data at the Laboratori Nazionali del Gran Sasso in Italy, with the main goal of searching for the neutrinoless double-beta decay (0nbb) of 130Te. This process is of paramount importance in particle physics due to its...
The European XFEL Free Electron Laser (EuXFEL) at DESY is operated at 2K since January 2017. The first laser light was produced in May 2017 while the user operation began in September 2017. The electrons are accelerated in pulses with a repetition rate of 10 Hz. Each pulse is about 1.37 ms long; 650 μs are used for beam acceleration.
An R&D program is ongoing at EuXFEL and DESY to investigate...
