LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945 EYETS 2016-2017: General infos LHC-EYETS completed on Sunday 30th April. All the activities must be completed by Friday 14th April IMPACT: intervention period EYETS-LHC-2016/17 Phone ‘piquet’: 161669 OSS website (planning, constraints, …): https://espace.cern.ch/en-dep-mef-lpc/EYETS2016-2017/Global%20Schedules/Forms/AllItems.aspx INDICO: https://indico.cern.ch/category/7198/ The access during the AUG test is according to a list  any access IN SURFACE need to be declared  NO access underground except EN-EL and EN-CV Unlock out W14 (3rd April - 7th April) LHC back to BE-OP on Friday 14th April LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945

Validation of level gauge klystron/RF cryo-module Proposed dates from coordination  week 8 Proposed date from TE-CRG  15th February (Tomorrow) NO ACCESS between green doors Activities schedule: Depressurising line C from 8:30 to 10:00 to 1.1b and then keeping line C to that pressure (return flow line D) Lock out of CV933 removed (only this valve) (1/2h) Then CV933 will be opened slowly to equilibrate pressure if any..(1/2h) Then positioner will be replaced + a ‘re-initialisation’ will be done (2-3h) And finally valve will be lock out again. IMPACT on BE/BI activities  BSRT LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945

Fire detection and ODH flash Fire detection in RA67  Installation of a fire detection tube, needed: VIC Work authorisation (Helium spill risk) Electrical lock out Cryogenics lock out ODH flash replacement in UJ14, ITs area  Move position in the transport zone?

Survey measurement w/o ventilation s.7-8 Test performed yesterday Shielding in UJ 84 closed Ventilation doors in LSS7R opened residual air flow 0.4 m/s Request from EN-ACE-SU to CLOSE the ventilation door in LSS7R  Safety authorisation required LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945

LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945 New request, BGI in LSS4R Replacement of BGI in LSS4R - Following the lasted investigations on the BGIs, it might be suggested that the 2 BGI chambers in 4 Right (D5R4) are replaced with drift tubes as done for D5L4. Please, can you let us know: 1. Are the replacement chambers ready of installation? If not, what is that status and when could they be installed? 2. What would be the impact on the planning if these BGIs were replaced with drift tubes? - Warm magnet lockout needed LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945

LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945 Non conformities BI in UJ22 Un diamond BLM a été installé durant un des TS-2016, selon ECR LHC-BLM-EC-0005 Il avait été validé que ce BLM soit installé coté passage. Il a finalement été installé à l’arriere, sous le BLM existant. BI RA43 Le BGV et ses accessoires ont été installés durant le LS1, selon ECR LHC-BGV-EC-0002. Les 2 tuyaux d’alimentation en gaz, reliant le rack en UA43 a la boite en RA43, n’ont pas été installés comme prévu ce qui obstrue la visée géomètres. Les 2 tuyaux reviennent à plat a 2390 du sol, soit au travers toujours de la même visée. Enfin, les 2 tuyaux remontent plus tôt que prévu, juste en face et tres proche du soufflet de la QRL, et le support au plafond n’a pas été intégré, et 1 de ses branches ne sert à rien. BLM on D1 in LSS1 and LSS5  decision to NOT re-install the BLMs LHC machine Schedule for LHC EYETS EDMS 1756963; INDICO 613945
