Time scale, Logistics, Recuperation

Time scale

• Start at T0 (after ultimate calibration!). Pb is T0 ?
• Removal duration: T0 -> T0 + 3 months

Logistics

• Start with Central & Slow Control electronics removal
  • T0 -> T0 + 2 weeks
  • Handled by Y.Miere, A.Augustinus
• Continue with Detector electronics removal
  • T0 + 2 weeks ->
  • Handled by Detector crew
• Additional support
  • EP Pool technician (at start)
  • 2 Ind. Support technicians
• Equipment to be scrapped (e.g FASTBUS FE modules)
  • Stored locally in containers
  • Containers regularly dumped in Pleney recuperation site
• Procedure for recuperated equipment (EP-Pool or Institutes)
  • Inventory / matching with EP-Pool lists in situ
  • Store modules/type in crates
  • Transport crates to EP Pool storage asynchronously
  • Keep non EP-Pool (i.e Collaboration) equipment locally

Recuperation

• Requests
  • LHCb: FASTBUS crates and PWS
  • COSMOLEP: Muon chambers + ?
  • OPERA: Ethernet equipment
  • Roma: HPC cables
  • Rio: Slow Control equipment (Gas station)
  • Bruxelles: PWS for education
  • Souvenirs
• Ownership vs Recuperation
  • EP-Pool equipment is owned by..EP-Pool
  • Collaboration equipment is owned by Institutes
  • Recuperation has to get the agreement of owners
    • EP-Pool: absolete available
    • CERN: Need to follow official exportation procedure
    • Institutes: ?

Online Cluster migration

Results of Cluster enquiry

• Future use of the reduced Online Cluster
  • Real need: Yes for ~50% of detector teams
  • Duration of use: 2001, may be 2002
  • Activity: Detector calibration, distorsion study, performance, casual use

Alphastations

• 34 units: Detector (19), Central Partition (7), Delpit (8)
• Destination
  • Home Institute : 10%
  • Delice : 12%
  • Online Cluster: 15%
  • Other (CERN): 15%
  • Not yet known: 48%

Online Cluster migration

• Time scale basically unchanged
  • Online Cluster stays up in Pit8 until Christmas
  • Detector stations are available for immediate removal
  • Early Jan. 2001: Re-installation of a reduced, but functionally identical Online Cluster (One week work)
