• Time scale, Statistics, Strategy, Logistics
• Removal / Re-use of FASTBUS Central Electronics (C.E)
• Removal of Slow Control Electronics
• Removal of FASTBUS Detector Electronics (D.E)
• Removal of non-FASTBUS, non-S.C equipment (CAMAC, NIM,..)
• Return of equipment NOT in Pit8

Time scale

• Equipment in Pit8 : T0 -> T0 + 3 months
• Electronics equipment NOT in Pit8 : T0 + 3 months ->

Electronics Statistics

• EP-Pool statistics (FASTBUS, NIM, CAMAC, VME, Lab instruments)

http://ess.web.cern.ch/ESS/Electronics_Pool
• General Purpose FASTBUS equipment (See appendice A)
• Slow Control equipment (See appendice B)

Strategy

• Minimize interference with detector dismantling
• Minimize use of cranes
• Optimize/rationalize use of PZ lift
• De-synchronize (UX85 -> SX8) and (SX8 -> outside) transports

Logistics & Infrastructure

• Dismantling, packaging & transport : DELPHI responsibility
• D.E: Under responsibility of Detector teams
• Detector enquiry on :
• Foreseen removal period, logistics aspects,..
• Return / Re-use of equipment e.g FASTBUS C.E
• Future use of Alphastations
• Meetings & Web info regularly updated
• Status of removal work
• Recommended/disfavoured periods (e.g B barrack moving)
• Central Electronics Coordinators :
• FASTBUS, NIM, CAMAC,..: Y.Miere
• Slow Control Equipment : A.Augustinus
• Manpower :
• C.E: 2 Ind. support technicians (3 months)
• D.E: ?
• Storage UX85
• C.E + D.E: area for PWS + Fans palettes (~10m^2)
• C.E + D.E: Small place for crates close to PZ entrance
• Storage of Detector F.E modules (gridded cages,crates) (~10m^2)
• Storage SX8
• C.E: Storage for palettes of PWS + Fans, crates full of modules
• D.E: Storage of F.E modules containers

Removal

• Start at T0 (after ultimate calibration!)
• Handled by Y.Miere + 2 Ind. Support technicians
• Briefing of Ind. Support people on Electronics removal procedure
• Marking (red spot) of all C.E equipment
• Procedure:
• D1: Remove PWS + Fans
• Dismount D1 crates one after each other -> PZ storage
• Collect all C.E from A,B,C,D
• Inventory / matching with EP-Pool lists
• Fill D1 crates with C.E modules of same type, in PZ storage
• Store small equipment (adapters,..) per family, separately in boxes
• Move up D1 crates and boxes
• Transport D1 crates to EP Pool storage asynchronously
• Potential problem
• We may have to keep/store modules NOT on EP-Pool inventory (SI, CI,..) or DELPHI specific (e.g FIPs)

Return /Re-use

• Detector enquiry
• Type of use (souvenir ?)
• Type, Number of C.E equipment needed
• Source : DELPHI private stock or EP Pool

• Start after FASTBUS C.E removal
• Handled by A.Augustinus + 2 Ind. Support technicians
• Procedure similar to FASTBUS C.E
• Remove S.C equipment
• Inventory / matching with EP-Pool lists in situ
• Separate out Detector / EP-Pool / Gas? equipment in situ
• Move up S.C equipement
• Transport S.C to EP-Pool storage asynchronously
• Store locally (in Pit8) Detector S.C equipment

• Start at T0 + 2 weeks, after removal of FASTBUS C.E and S.C
• Handled by Detector teams (+ 2 Ind. Support technicians: EP-Pool stuff)
• Deal first with FASTBUS D.E (F.E, specific trigger modules,..)
• Potential problems :
• Only 60 (non EP-Pool) crates usable to store modules
• Need of gridded boxes, containers,.. for F.E modules
• A,B,C,D :
• Uncabling ?
• Remove PWS + Fans
• Dismount crates one after each other -> PZ storage
• Move up F.E modules containers & (crates + PWS + Fans) palettes
• Transport F.E modules containers to their storage site
• Transport (crates + PWS + fans) palettes to EP Pool asynchronously
• Store locally (in Pit8) DELPHI equipment (e.g. FASTBUS crates, PWS) ?
• Also remove FASTBUS equipment in SX8 Labs

Type

• CAMAC, NIM, VME crates & modules
• Lab. instruments (Oscilloscopes, Generator/Timer,..)

Removal

• Start after FASTBUS D.E removal
• Handled by Detector teams + Y.Miere + 2 Ind. Support technicians
• Problem
• Tracability : Equipment borrowed by someone, accounted to some responsible and used by somebody somewhere
• Responsibility : Borrower, account responsible, user ?
• Possible procedure
• Detector teams remove equipment in their racks
• Central team remove equipment in its racks
• Inventory / matching with EP-Pool lists in situ
• Separate out Detector / EP-Pool equipment in situ
• Move up all equipement
• Detector team organise transport of their equipment to its destination
• Central team organizes transport of the EP-Pool equipment
• Also remove NIM, CAMAC, Lab. equipment in SX8 Labs

• Start after all Pit8 electronics removals
• Handled by ?
• List EP-Pool equipment not yet returned (from EP-Pool inventory)
• Try to localise it
• Ask owners to deal directly with EP-Pool

From T0 on

• Online Cluster stays up in Pit8 until Christmas holidays - (2-3)days
• Detector stations are available for immediate removal

Christmas - (2-3 days)

• Transfer of AXDES1, AXDES2 and AXDEOP to Lab.13
• Early Jan. 2001: Re-installation of a reduced, but functionally identical Online Cluster (One week work)

System Management

• Coordinator : D.Ruffinoni
• Future : Based on D.R + J.P.Chavanel (part time under new Computing Outsourcing contract)

Future use of the reduced Online Cluster

• Real need (Y/N)
• Duration of use (2001,...)
• Activity (Final detector performance analysis,..)
• Special needs (detector data storage,..)

Destination of Detector Alphastation

• Home Institute : shipment under Detector responsibility
• DELICE : Introduction possible from T0 on
• Replacement of current DELICE station
• New DELICE node
• Lab.13 Online Cluster node : Jan. 2001
• Somewhere at CERN : migration under Detector responsibility

(Warning: the limited internal disk capacity can prevent any migration e.g UNIX)
