BE-CO YETS 2015/2016 Planned BE-CO tasks during the YETS 2015/2016 Hardware Software, Services Thanks to input from C. Dehavay, B. Ninet, M. Said, S. Catin, J.C. Bau, A. Dworak, D. Cobas, G. Kruk, A. Bland and others

GMT Timing Distribution front back Current installation front back MTG - Master Timing Generation What do we see on the pictures? Need information what is really going to be renovated Solution with fiber

GMT Timing Distribution Replacement of old timing distribution based on VH4 copper cables by fiber optics Fiber optic cables already partially in place Wait for missing fiber requested to EN/EL . We don't know yet if they will be install during this YETS Installation/Replacement of the distribution crates Old crate will not be kept as backup, we are confident with the new equipment MTG - Master Timing Generation Benjamin: Rénovation/Repérage distribution Meyrin (Chassis distribution) Benjamin: The final strategy is not defined yet. Because we have not enough hardware to replace the old one and all the fiber request made by my predecessor are not installed.

GMT Timing Distribution Prepare the replacement of cables where fiber has been requested Check all the MTG connections in PSB to see if and for what they are used (PLS-SU or FEC) Locally distribute timing in building 151 for RF CPS 1- turn feedback cavities MTG - Master Timing Generation Benjamin: Rénovation/Repérage distribution Meyrin (Chassis distribution) Benjamin: The final strategy is not defined yet. Because we have not enough hardware to replace the old one and all the fiber request made by my predecessor are not installed.

Pulse Repeater new ^^ CTDAH (back) new Current Situation CTARA (front)

Pulse Repeater Current installed hardware is already over 40 years old and the cards used are obsolete New hardware solution partially developed and ready for deployment TTL ← → BLOCKING (ready) TTL ← →RS485 (under development) Hardware to be installed in ELMA VME crate providing SYSMON interface Start of renovation* PSB, building 361, BCER677 CPS, building 355, PR86 *Only PSB or CPS will be done during YETS 15/16, decision will be taken Dec/2015

OASIS Renovation of cfv-351-ciaos1 VXI in Linac3/LEIR → installation of 1 new FEC Renovation of cfv-353-cpaos01, cfv-353-cpaos02, cfv-353-cpaos09 VXI in CPS → installation of 3 new FECs Installation of cfv-361-cbaos6 to replace the Tomoscope Upgrade of cfc-361-cbaos7 by adding 2 new digitizers

Remote Reset Install Twido in SPS in building 870 (BA3) and 905 (BB3) Installation 1x Twido in building 151 for RF CPS 1-turn feedback cavities

Deconnection, Destruction Disconnection of cables in PSB already identified to be removed until end of LS2 PSB Injection Timing (cfv-361-ctinj) PSB Ejection Timing (cfv-361-ctej) PSB Fast Ejection, Kickers (cfv-361-mkpsbej) PSB shavers timing (cfv-361-ctrg) PSB semgrids (cfv-361-bibtm) PSB orbit and trajectory system (cfv-361-bpmpsb) B-Train RF and REV, Acquisition Septa, Timing Oasis , Gate BLM Tail clipper, external conditions Cables will be only disconnected, but not removed yet! Dismanteling of FEC dpsbrf2 used for the old Low Level RF in PSB

LEIR, PSB Transverse Feedback Renovation of transverse feedback for LEIR (cfv-363-all2) and PSB (dpsbtrfb) Request just arrived last week, not all details clear yet Needs more discussion with RF to understand their renovation plans Renovation of software seems to be the limiting factor This topic is highly questionable! We first have to talk to Alfred Blas, as he seems to lack information what has to be done, what are the consequences of that.

Infrastructure, InCA Infrastructure - Monday 4.January to Wednesday 6. January Updates of Servers and Consoles Especially Monday most of the services will be not available due to update of the NFS servers As usual we attempt to not affect TI Operation, Access and Cryo too much Don't expect Working Sets to work, don't schedule e.g. Magnet pulsing in this period InCA - Monday 11.January to Wednesday 13. January New InCA release, changes related to automation of CCDB-LSA DB synchronisation (devices and properties) During these 3 days InCA/LSA services won't be available (working sets, knobs, LSA applications), don't schedule e.g. Magnet pulsing in this period

Timing Timing Short disruption of the timing services during January Foreseen timing interventions Upgrade of cs-ccr-ctm → Disruption of the DTM distribution for all machines Upgrade of LIC central timing for Awake project → No GMT and DTM timing distribution for CPS, PSB, LEI, SPS machines. Interventions normally less than 10 minutes Upgrade of White Rabbit switches in buildings CCR, 2008, 354 and 193 → Timing perturbations on CPS, PSB, LEI, SPS, ADE, CTF machines. Interventions normally less than 30 minutes

Drivers Deployment of PCI/PCIe geographical board location scripts This potentially impacts all PCI/PCIe based FECs OVERALL. Can be done at any moment during YETS, planned before the global FEC reboot beginning 2016 causing 1day of downtime around 3-4 Jan Deployment of new encore-based drivers for CVORJ and CVORA Deployment of new installation schema for Struck sis33** boards and also MTG (drivers.xml removed, transfer.ref only reference) To be decided, but the expected impact/downtime is always the same → Reboot of the FEC No system unavailable except during massive reboots during infrastructure updated and reboots of the FECs
