PSB In progress – On site preparations for the beam dump replacement project on schedule. New beam dump core delivered to CERN and is under preparation. Dismantlement of the BTM/BTY beam lines now complete. Final zone cleaning in preparation. EN-STI Successfully Injected foam to aid the cutting of the old beam pipe. Start of the beam dump removal procedure currently programmed Wednesday 07 th August. No general access to the PSB Machine during this period. – CV consolidation and maintenance of CV, kickers, Septa, vacuum beam instrumentation, Magnet and Beam stopper – AS45 lift replacement final commissioning 16 th Sept. Forecast – Replacement of all PSB ring 32A power sockets which are not protected by a differential – Integration testing of the new PPS (access) system Installation of the public address cables & infrastructure. – Replacement of the BI.SMH under preparation.

General infrastructures The possibility of deploying Wi-Fi access points at each LHC pits (PAD – MAD on surface) is under study. A slight slowdown in the project of technical network renewal (due to vacation period) but still quite ahead of the schedule. Demineralised water production – work is finished !! 400kV & 66kV maintenance and consolidation – CERN ends end of July – But auto-transfer test postponed to end of August 01/08/2013LSC - K.
