Laurent Delprat (CERN)23/07/2024, 11:00ICEC 01: Large scale refrigeration and liquefactionInvited Oral (30m)
Capitalising on the cryogenic operation experience of the LHC (Large Hadron Collider) at CERN and thanks to the promising results of the R&D efforts, the first phase of the Future Circular Collider (FCC) study presents in its Conceptual Design Report (CDR) published in January 2019 a clear route to a post-LHC machine, expected to be housed in a new 91km circumference underground tunnel....

The LCLS-II, an advanced X-Ray light source operated by Stanford University at SLAC for the US Department of Energy (DOE), operates with 37 cryomodules and a 700-meter linear accelerator (Linac) linked to two Cryoplant units, each capable of generating over 4.0 kW at 2.0 K. Commissioned in 2023, the LCLS-II Cryoplant is managed by the SLAC Cryogenic Division. This paper presents a...

In 2023, SLAC commissioned a continuous-wave superconducting linear accelerator (CW SCRF Linac) to bolster its new Linac Coherent Light Source (LCLS-II). The Linac comprises of 37 cryomodules operating at 2.0 K. Achieving the 2.0 K temperature in the Linac involves reducing the liquid helium saturation pressure to 31 mbar using a series of centrifugal compressors, commonly referred to as cold...

The upgrade of the SLAC National Accelerator Laboratory's Linac Coherent Light Source (LCLS) to LCLS-II marks a significant advancement in accelerator technology, incorporating a superconducting linear accelerator enhanced by 37 cryomodules segmented into two LINAC sections. This configuration, with 17 cryomodules upstream and 20 downstream, is uniquely supported by one of two helium...

The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN is a major upgrade project of the LHC accelerator, which should allow increasing the peak luminosity by at least a factor of five beyond LHC’s design value. This upgrade will include the replacement of the final focusing superconducting magnets and the implementation of superconducting radiofrequency crab cavities in the...

311. Process design and control strategies of the two large 1.9K Helium refrigeration plants at CERNEriks Arajs (Linde Kryotechnik AG)23/07/2024, 12:30ICEC 01: Large scale refrigeration and liquefactionRegular Oral (15m)
In 2022, Linde received the order to deliver two large helium refrigeration systems operating at 4.5 K and 1.9 K for the European Organization for Nuclear Research (CERN) in Geneva, Switzerland. The two identical plants will be installed at opposing points along the circumference of the Large Hadron Collider (LHC). They will facilitate the peak luminosity by a factor of five beyond the LHC’s...

The CMS and ATLAS experiments and their superconducting magnetic and calorimetric systems, installed in the LHC (Large Hadron Collider) at CERN, have both been equipped with cryogenic installations. The CMS experiment is making use of a large superconducting solenoid magnet, while the ATLAS experiment combines a large superconducting toroid magnetic system, a superconducting solenoid and three...
