32. Dynamic simulations: a useful tool for cryogenic installations

Benjamin Bradu (CERN)

In the last decade, several tools have been developed and used to perform dynamic simulations for various cryogenic installations over the world. A summary of these different studies is presented here, focusing on the interests of performing such dynamic simulations for existing and future cryogenic installations.

29. LHC machine operation: what did we learn?

Mr Gerard Ferlin (CERN)

The cryogenic system of the Large Hadron Collider (LHC) has been in production mode since 2007.
This presentation will explain the general structure of the cryogenic system of the LHC, the installation and commissioning strategy followed and the evolution of the operation from its “expected mode” foreseen during construction phase, to its “consolidated mode”.
The second part of the...

31. Refrigerator and recirculator system for U.S. ITER central solenoid module fabrication program

Mr Lars Blum (Linde-Kryotechnik)

The central solenoid magnet forms the heartbeat of the International Thermonuclear Experimental Reactor (ITER). The 12.8 meter high magnet will consist of six solenoid modules, each weighing 110 tonnes. General Atomics is currently fabricating these modules under a contract managed by the US ITER Project Office at Oak Ridge National Laboratory, sponsored by the Department of Energy’s Office of...

30. Wendelstein-7X: first experience with cryogenic system

Chandra Prakash Dhard (Max-Planck-Institut fuer Plasmaphysik)

In February 2015 began the cool-down of about 450 tons cold mass of Wendelstein 7-X i.e. 70 superconducting magnets, 14 currents leads, massive support structure and the thermal shield, enclosed within a vacuum vessel of about 15.4 m outer diameter. Since then, the components are maintained cold at various temperatures i.e. <10 K for short standby, 3.9 K for standard and 100 K for long standby...
