1. Hardware Commissioning Review BDI Equipment
R. Jung, on behalf of the
BDI LHC Technical Board

2. Hardware Commissioning Review & BDI Equipment
BDI equipment is not part of the Hardware commissioning proper
BDI may/will interfere with the Hardware Commissioning due to late monitor deliveries
BDI equipment is mainly concerned by the commissioning with BEAM
Different categories, with different impact:
Large distributed systems over whole LHC
Many specialised systems in small numbers around IP4, injection and dump extraction

3. BDI systems installed in LHC tunnel
Two big distributed systems: BPM & BLM
Two Luminosity Stations: IP1 & IP5: US LARP: pb
Special systems at Injections & Extractions/Dump lines
Many special systems installed around IP4:
BCTs: Fast and DC monitors
Special Pick-ups for Tune, Chromaticity
Transverse Profile Monitors: BTV, BWS, BSRT, BGIH/V
Longitudinal Profile Monitors: WCM
Our reference: Sylvain Weisz’s planning
Our Aim: ready for the LHC start-up: July 2007

4. Large Distributed Systems
BPMs:
Arcs: follow SSS planning: OK
Others: Just In Time : BPM_A Q7R8
Warm BPMs: may be JIT for LSS8 end
Electronics: small pb with delay lines order & deliv:
4 cards/Q may have to be installed later: access needed
BLMs:
4000 ICs production will start in Prodvino: ~JIT; if not: install 2 ICs / Q and come back later: Access
Last IC installation after interconnect closure only
IC on passage to be installed after last transport
~340 SEMs for SSS, IR3 & 7, after IC production

5. Special & Small Quantity Systems [IP4]
BCTs
Available for installation in June/July 2006
Special Pick-Ups
JIT, including Schottky for the moment
Transverse profile Monitors
BTV in IP4 + elsewhere in ring & dump: JIT for IP8R
Wire Scanners: JIT
BSRT: JIT
BGIH/V: fragile equipment to be installed as late as possible
Longitudinal Profile monitors: RF WCM: OK
Interference with start of RF tests [15/06/06]
Little interference with RF commissioning: 11/06 – 5/07

6. Open questions: IP4 & Dump Lines
IP4: Access to UA43 & 47 (ex klystron galleries) during RF tests & commissioning: shielding
Dump Lines
Exact location & dimension of vacuum chambers for BCT and screens to be defined with AT/VAC and AB/BT to start ASAP the mechanical design of these BCTs and special large screen [ROI] BTVs.
