Report from LHC String 2 Run 1

by R. Saban (CERN-AC)

Thursday 28 Feb 2002, 14:15 → 16:15 Europe/Zurich

Please note that this seminar will take longer than the usual LHC Project Seminars and therefore an agenda for the presentations is proposed: 14:15 R.Saban, General Commissioning and Run 1 Report 14:30 B.Skoczen, Interconnections, Line N 14.45 C.Rathjen, Quench Induced Currents in the Interconnects 15:00 L.Serio, Cryogenics 15:15 F.Rodriguez-Mateos, Magnet Protection 15:30 F.Bordry, Powering 15:45 L.Bottura, Field Tracking between Dipoles and Quadrupoles After the commissioning and the first powering of the main circuits in autumn 2001, a short yet vigorous experimental program was carried out to validate the final design choices for the technical systems of LHC. This program included the investigation of thermo-hydraulics of quenches, quench propagation, power converter controls and tracking between power converters, sum currents induced in the interconnects after a quench. Parameters significant for the LHC, such as heat loads, were also measured. After a brief description of the configuration of all the systems and a summary of the run, the experiments, their objectives, results and conclusions are reported.
