Experimental simulation of helium discharge into the LHC tunnel.

Author(s) : CHOROWSKI M., KONOPKA G., RIDDONE G., et al.

Summary

The LHC cryogenic system contains about 100 tons of liquid helium. The largest amount of helium is located in the magnet cold mass (about 58 tons at 1.9 K, 0.13 MPa), in the QRL supply header C (about 26 tons at 4.6 K, 0.36 MPa) and in the ring line (about 0.7 tons at 290 K, 2 MPa). The rupture of header C is one of the failures leading to the worst scenario of helium discharge into the tunnel. To investigate the consequences of this failure, an experiment has been performed. The paper presents the layout of the test set-up and compares the experimental results with calculated data.
