1. Injectors & LHC report S. Baird and M. Bernardini on behalf of OSS members 20/09/2013LSC - EN-MEF-OSS1

2. AD & LEIR 20/09/2013 LSC - EN-MEF-OSS 2 AD – Girder line 7000, procurement of material in progress, but some delay due to change of material (361 LN instead of 316L for a few chambers). – BHN06: official decision circulated – UHM3107 and UVM3207 tanks : Pumping and leak test in progress – KFI tanks reinstallation expected mid Oct.- final leak tests in progress – Installation of a railing for OD in progress LEIR – Successful brief opening vacuum sector 5 (removal IMP’s) last week.

4. PSB In progress – PSB beam dump replacement project on schedule. Survey of the beam dump cavity revealed a downward slope of 1cm over 2 M. The beam dump cavity is not continuous and is made up of 2 cylinders of 3 and 2 meter lengths respectively. At the junction of the 2 cylinders, a slight descent of the 2 nd downstream cylinder explains the discontinuity of the rail profile. Civil engineering are to drill and extract samples from the dump foundations in order to analise the composition of the base materials (soil or concrete). Depending on the outcome, Civil engineering may have to inject a stabilising resin into the beam dump foundations possibly delaying the beam dump installation by ~ 3 weeks. – CV consolidation and maintenance of CV, kickers, Septa, vacuum beam instrumentation, Magnet and Beam stopper, cabling campaign. – Replacement of PSB ring 32A electrical power sockets. Completed. – Decontamination of the beam dump cavity. – HV power testing & validation of the repaired Technix BI.DIS power supply.

Work to start wk 42 (14/10/2013) – Terminate and reception the access control MAD. – Survey & alignment of the BI and BT line magnets. 28/08/2013LSC - S. Baird4
