CSE General Meeting 2020
News > Announcements | November 26th, 2020
Due to the Covid-19 pandemic this year's European Cryogenics Day and the General Meeting (GM) of the CSE could unfortunately not take place as originally planned.
The GM 2020 will now be organized as online event on zoom and is scheduled for December 3rd, 2020 starting at 8:45 am CET.
This event opens with a virtual get-together allowing us to setup the meeting and arrange for the voting process in the General Meeting. The GM will start at 9:00 or shortly after, as soon as all participants have been registered. After the General Meeting of the CSE, we will have a program with three presentations.
Please use the following link for registration: https://forms.gle/eqPqhE9jgPPbRZrW8
Also presenters that have submitted abstracts are requested to register for the meeting via the link.
The tentative schedule is as follows:
08:45 opening Zoom session, virtual get-together and registration (agenda)
09:00 General Meeting of the Cryogenics Society of Europe
10:20 (Virtual) Coffee break
10:30 Pascale Dauguet, Air Liquide: “Review of Air Liquide last 2K Cryoplant projects and last turbomachine developments” (abstract)
10:45 Sun Nora-bo, Pride Cryogenics: “Introduction to Pride Cryogenics: company and main products” (abstract)
11:55 Bellisimo Yu, Vacree Technologies: “Introduction to Vacree Technologies” (abstract)
11:05 Final remarks
Please note that only CSE members have right of voting at the GM but attendance is open to non-members as well. Feel free to forward this communication to any interested party.
We look forward to welcoming you at the GM2020!

Abstracts of the presentations
Review of Air Liquide last 2K Cryoplant projects and last turbomachine developments
Authors: J.-M. Bernhardt, C. Gondrand, Y. Fabre, P. Dauguet
Refrigeration power at 1.8K or 2K is needed for most of the large particle accelerators, in order
to get optimised operating conditions of superconducting RF cavities. Air Liquide has
developed (since the 80's) Cryogenic Centrifugal Compressors in order to decrease the
pressure on helium baths down to liquid/gas equilibrium pressure in the range 10-30 mbar abs.
for 1.8K-2K helium bath temperatures. These compressors have demonstrated their reliability
and efficiency, with references successfully operated for more than 10 to 30 years at CEA Tore
Supra (now WEST), JLAB CEBAF and CERN LHC. The projects needing 1.8K - 2 K
refrigeration have multiplied in the last 10 years thanks to huge investments of US, Chinese
and Korean governments in the field of accelerators, giving us opportunities to design,
manufacture, install and start-up new 2K Cryoplants and apply our last turbomachine
developments to these projects. The presentation will be a short review of some of the last Air
Liquide 2K Cryoplant projects and turbomachine developments.
