Study of Mechanical Disturbances in Superconducting Magnets using Piezoelectric Sensors and Quench Antenna
/ Artoos, K ; Dezillie, B ; Mompo, R ; Siemko, A ; Tommasini, D
Mechanical disturbances in superconducting magnets were studied by recording and characterising the signals induced in piezo-electric ceramic sensors (piezos) and accelerometers by spontaneous acoustic emission (AE) during magnet excitation. The localisation of AE sources as recorded by the piezos corresponds to the localisation obtained by another, indirect technique, the so-called Quench Antenna. [...]

Energy Extraction in the CERN Large Hadron Collider : a Project Overview
/ Dahlerup-Petersen, K ; Erokhin, A ; Kazmine, B ; Medvedko, A S ; Sytchev, V V ; Vasilev, L B
/CERN-Russia Collaboration
In case of a resistive transition (quench), fast and reliable extraction of the magnetic energy, stored in the superconducting coils of the electromagnets of a particle collider, represents an important part of its magnet protection system. In general, the quench detectors, the quench heaters and the cold by-pass diodes across each magnet, together with the energy extraction facilities provide the required protection of the quenching superconductors against damage due to local energy dissipation.

Molecular desorption by synchrotron radiation and sticking coefficient temperatures for H$_{2}$, CH$_{4}$, CO and CO$_{2}$
/ Baglin, V ; Collins, I R ; Gröbner, Oswald ; Grünhagel, C ; Jenninger, B
A cryogenic vacuum system has been used to study both the surface pumping of gases and the molecular photodesorption yield from OFE copper in the temperature range from 5 K to 300 K. The sticking coefficient on a `bare surface´ was found to increase with decreasing temperature of the substrate and below 20 K, to be in the range of a few percent for all gas species studied. [...]
