DRY RUNS 2015 Status and program of the Dry Runs in 2015 Update of the presentation given at LBOC Status and program of the Dry Runs in 2015 (although many things have been already Dry Run in 2014 and tested with beam during the Transfer Line Test, in 2015 we start from scratch) On behalf of V. Kain, M. Solfarolli, D. Jacquet, R. Giachino, M. Albert, L. Drosdal, J. Wenninger, B. Salvachua, D. Nisbet and all Equipment Experts & Experiments Disclaimers: the Dry Runs presented here don’t cover: Machine Protection Tests which are responsibility of MPP + Software Interlock System Tune and orbit Feedbacks (presented at the LMC #203 by Jorg) Vacuum valves control commissioning (by M. Albert) 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting LHC Injection Kickers (MKI) MKI control from application MKI control from sequencer Softstart (new values in the control system for RUN2 available) MKI settings: currently using RUN1 settings  to be tune with beam OASIS 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting LHC Timing System Send events Telegram Load/unload tables, trigger tables Timing application Injection protocol with dynamic destination LHC mastership LHC injection sequencer Beam permit 1 and beam permit 2 reception coming from BIC (CCR) after the BIC loop is open (via CIBG stop) and triggering of HX.PM1-CT and HX.DUMPEDx-CT Post Mortem reception by the experiments Injection test mode (with key), HIX.FW-CT generation and pre-pulse Instabilities trigger DONE 26/02/2015 Sector Test preparation meeting BIC: Beam Interlock Controller

Sector Test preparation meeting LHC RF System LHC-SPS RF re-phasing LHC RF synchronization RF Low Level Tested yesterday again LHC-SPS rephasing with beam in SPS requested by LHC Injection Sequencer with mastership 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting LHC Injection Quality Check System Tested yesterday again All the analysis modules working  Missing only MKI IPOC and OFSU data (Injection oscillations) which is expected. BQM, BLMs and BPMs now working again. Application operational Dynamic destination More BLMs still to be integrated for analysis in 2015 DONE 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting Experiments Handshakes Accelerator/Beam modes Injection inhibits for ALICE & LHCb Post mortem reception 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting LHC Beam Instrumentation TRANSFER LINE INSTRUMENTATION  being checked today, issues spotted during transfer line test have been fixed. LHC RING  BLMs: 1 Hz acquisition for fixed display and logging XPOC(1) (4 BLMs around TCDQ have changed name and needs update) Post Mortem IQC Collimator  to be tested this week BPMs: FIFO acquisition (beam threading on first turn) (problems with BPM names solved) CAPTURE (for IQC) CONTINOUS (Orbit)  to be tested (IQC injection oscillations) Concentrators needs more test: loading/stability BLM FIFO acquisition for B1 FIFO acquisition for B2 (1) XPOC: eXternal Post Operational Checks 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting LHC RING (CONT) BTVs: being tested as part of MPP commissioning (M. Albert) DUMP LINE  BLMs : OK (4 monitors names to be changed around TCDQ) BTVDD: being tested as part of MPP commissioning (M. Albert) BPMD: to be tested as part of MPP commissioning BCT: to be tested as part of MPP commissioning / device still under expert individual system test 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting LHC Beam Interlock System (BIC) So far only armed with LBDS with operational sequence Arming with User inputs for sector test as from Tuesday next week LHC Software Interlock System (SIS) Commissioning is ongoing LHC Safe Machine Parameters (SMP) Safe Beam Flag  Issue with the transmission of the beam intensity (IR4) to the SMP (CCR) solved Beam Presence Flag  to be tested with beam 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting Vacuum Status for Sector Test: TI2- LSS2 to LSS3 and TI8-LSS8 to LSS6  All sectors under vacuum! LHCb: The pump down of LHCb was started last Friday (13.02.2015), today (18.02.2015) we have a pressure of 1E-9 mbar and today we’ll re-start the ion pumps in the VELO tank that give an interlock signal to the sector valves. ALICE: The manual valve between the IP2 and the vacuum sector A1L2.X will be open during next week to allow then the injector test. 26/02/2015 Sector Test preparation meeting

Transfer Line circuits Extraction to TT40 & TT60 foreseen this week  good opportunity to test the SPS Extraction BICs The transfer line power converters were switched on 20.02.2015  issues being followed up The only PC we were unable to start was... SR8.RCIBV.88116 (String:1) -> 380V VS VS_RUN_TO BA6.RBIH.610337 - Not following function- measured approximately 0.043 A lower than function 26/02/2015 Sector Test preparation meeting

Sector Test preparation meeting To be scheduled a heat run To be tested the interlocked ones BA4.RBIH.80407 - Not following function - measured is approximately 0.5 A greater than function. BA4.RQID.80100 - Not following function - measured approximately 1.6 A greater than function. BA4.RQID.80300 - Not following function - measured approximately 2.2 A greater than function BA4.RQID.80200 - Not Following function - measured approximately 1.6 A greater than function. 26/02/2015 Sector Test preparation meeting
