Transcript of Critical Equipment -...
Critical Equipment - Preparations Through R2E we started to collect the list of requirements of the most
critical systems (based on current knowledge) in terms of a required
relocation
To first check the approach a first example was performed for the PIC
installed in Point-1 (with M. Zerlauth an colleagues)
To combine operation, integration constraints and radiation levels we set
together with A.L. Perrot and the respective Point-Owners and agreed on:
Point-Owners will check the list of selected equipment and their respective critical
locations
A.L. Perrot looks into possible new locations and verifies integration constraints
the respective equipment responsible are contacted to retrieve a list of requirements,
time constraints and related issues
For LHCb as well as the other critical points some first answers are
available

Example: PIC in UJ14/16 (same for UJ56)M. Zerlauth, B. Todd, B. Puccio, P. Dahlen:
would need to re-locate the 6 PLCs(for 6 Powering Interlock Controllers currently in UJ14 and UJ16) :
Find a new location, with space for 6 PLCs of type 319 - half an LHC rack would be sufficient, location identified in US15
UPS power + 6 Ethernet connections are needed in this new rack Pull/Extend 1 Profibus cable / PLC, thus in total 6 cables from the current
rack CYCIP01=UJ14 / UJ16 to the new destination Pull/Extend 1 Remote reset cable / PLC, thus in total 6 cables from the
current rack CYCIP01=UJ14 / UJ16 to the new destination Probably also need two additional power supplies to go into this new rack
(provided by us) This solution will re-loacte the PLCs, but does not concern (yet) the power
converter/QPS cabling, thus is still rather easy to be done. As soon as all cabling, Ethernet and UPS power is available, the re-
location could be done in a couple of days only (physical re-locationonly ~ 1 day, updating configuration and supervision systems 1-2 days,probably a day for re-commissioning)
To be on the safe side “say a week...”
May 28th 2009 2Current Status of Preparations of 'Early Relocations'
AL3 (Rui Nunes): Relocation required before startup (risk of undetected fire)
concerned areas: UJ76 (improved through local shielding)
US85
UJ56
Relocation to UL/UA or surface possible
Fire control equipment more easily to be moved to the
surface, for ODH limitations on the cable length exist
(UL/UA possible)
R. Nunes started to prepare the list of requirements and
time estimates, currently bottle-neck in his group to retrieve
further details
Detailed planning and preparations required for the next
step

UPS (Gunnar Fernquist): concerned areas:
UJ56
UJ76 (done)
US85
required time (estimate) given as long (~4months), where 3
months were estimated to get cables; the latter can be
faster if required as local stock exists
UPS support can be installed in parallel
power cut required for about 4-7 days, issue for cryogenics
checked with Point-Owners and not a problem (sector can
remain floating for 3-4 weeks)
one week of re-commissioning
at P8 (US85) relocation in the UA possible

Timing, Remote Reset (Roland Chery): concerned areas:
UJ14/16
UJ56
UJ76
US85
underground location is required because of limitation in cable length
usual delay for ordering the required cables, installation time of cables to
be verified with J.C. Guillaume
the actual relocation and re-commissioning is fast
in addition many concerned racks also contain the WorldFip equipment
(Raymond Brun), thus this has to be coordinated accordingly
important dependencies for the remote reset rack (cables and
interconnections), detailed planning required also for depending
equipment
for P8 it is interesting to note that the „clients‟ of the remote reset are
mostly (except Timing) are all located in the UAs where radiation levels
can be considered as significantly better than in the US

WIC (Pierre Dahlen): concerned areas:
UJ14/16
UJ56
US85
the system can be relocated and the maximum possible distance is
500m
find a new location: 1/2-1 LHC rack would be sufficient for P8
UPS power + Ethernet connections are needed in this new rack
pull/Extend 1 Profibus cable / PLC and 1 Remote reste cable / PLC
probably one additional power supply for the new rack
this solution will relocate the PLCs, but not concern (yet?) the WIC
cabling, thus is still rather easy to be done.
as soon as all cabling, Ethernet and UPS power is available, the re-
location could be done in a couple of days only (physical re-location only
~ 1 day, updating configuration and supervision systems 1-2 days,
probably a day for re-commissioning).

Collimation Control (Alessandro Masi): concerned areas:
UJ14/16
UJ56
the system can be relocated
required amount of cables, power requirements and other
communication infrastructure are known
preparations can start as soon as final locations are specified
dedicated radiation test performed at CERF; achieved only limited
intensity, however giving confidence that only limited problems will occur
during 2009/10 operation
