CDF Decommissioning StatusJonathan Lewis
Master Planning Meeting
9 November 2011
Overview
• PPD is implementing Phase 1 of the DOE-approved decommissioning plan Remove all hazards related to the
experimental program Put experimental areas on display to be
included in Fermilab’s educational visitor program
J. Lewis--CDF Decomminssioning Plan2
J. Lewis--CDF Decomminssioning Plan3
Scope• All hazards related to CDF experimental program
mitigated • 2nd floor, collision hall and adjacent section of
Tevatron tunnel ready for tour groups of ≤49 people• West high bay cleared for iARC use• East high bay prepared for PPD detector
development and construction lab • Assembly pit prepared for joint PPD/iARC use• Office areas and 1st floor counting room cleaned and
ready as adjunct to PPD activities in high-bay• 3rd floor computer room for CDF analysis servers

J. Lewis--CDF Decomminssioning Plan5
Schedule
• October-December Secure detector Recover electronics Cleanout highbays
Consolidate/remove cabinets Remove gas racks, motor-generators, etc.
• December Demolish mezzanines
• January IARC construction begins
No access to west door Recover PMTs, etc. from detector
Schedule, cont.
• March-April Remove cable bridge
• April IARC tie-in work on north side Begin collision hall work
• Ongoing Counting room clean-up Remove process systems Life safety improvements for tours IARC integration
J. Lewis--CDF Decomminssioning Plan6
Status
• Systems secured No flammable gas or HV All detector power off Solenoid warm
• Clean-up in full swing Priority to recover of items useful to other efforts Throwing away CDF-specific items as we encounter
them ~30 skids out the door in the past month
• New lab space for mu2e 2nd floor work room, main floor welding area Trying to make more space soon to meet demand

Gas racks gone
Scrap
Mezzanine ready
for demolition
MGs and test magnet
ready for removal
!st floor CR being cleared
Coordination with IARC• Electrical
Freeing up experimental power substation Moving conduit for doorway
• Mechanical Coordinating moves of sprinkler and chilled water
pipes for interferences with interconnects, etc.
• Mezzanine removal• Planning (Dervin Allen)
Tours for A&E, contractors, etc. Locating utilities, electrical circuits Reduced generator needs during utility work Evaluating access, connections
Truck access CDF roof access etc. etc. etc
J. Lewis--CDF Decomminssioning Plan9
CDF Building Improvements on D&D Budget
• Main Stairwell Remove abandoned chilled water pipes Relocate elevator pump
• 1st Floor Remove abandoned chillers, etc.
• 2nd floor Improve exits Isolate conference rooms and egress paths from
assembly area
• Collision hall Sprinklers Fire doors Exit lighting

Plans for Display
• Theatre Place for visitors to assemble
Meet scientist? Movie?
• Trigger room Electronics on display Other displays?
• Control room Flashing screens look almost like we are running
• Collision hall North and west sides blown open
Plastic covers, view of COT face, etc. South and east, closed up in running configuration
J. Lewis--CDF Decomminssioning Plan12
Display Effort• Working with Public Affairs and Education• Making posters to document our achievements
Mix of hardware and physics Ben Kiliminster coordinating
• Interactive activities geared mostly toward middle school Cosmic-ray test stand, etc.
• CDF people: Ben Kilminster, Anna Mazzacane, JDL
• Life safety improvements in tour areas Doors, walkways Remove obstructions Remove halon, sprinkler mods

Storage of components that may have future use
• Detector Items They are safe in situ Not worth labor to pull down if no use identified
Phototubes, Radeka preamps, etc.
• Shelf Items Over the years CDF has collected lots of good stuff
What you want for a detector lab (fittings, valves, connectors) We will sort to keep what is most generally useful
Don’t want building to be a warehouse Plan for storage mezzanines in pit alcoves without crane
coverage Sufficient space for all lockers now in high-bay
