Background on Muon Campus plan

• Earlier Plan had 5 Common Projects:  MC1 Building (GPP) MC Beamline Enclosure (GPP) MC Site Preparation (GPP) MC Cryo Plant (AIP) MC Delivery Ring Upgrades (AIP)

• This plan has evolved in response to Recommendations made at Mu2e

DOE CD-1 review Maturing designs for (g-2) and Mu2e

• Recycler AIP was added in response to DOE recommendation and includes scope that was originally part of the g-2 project

• Scope of Site-Prep GPP changed in response to DOE recommendation that resulted in acceleration of Mu2e civil construction schedule

2

• Muon Campus projects plan actively orchestrated and managed via regular program meetings

• Although the packaging of the projects has been in flux, most of the individual jobs to be done are well-known and mature

• Aiming for Director’s review of full program in next few months

MC-1 GPP

MC-1 building to house g-2 and future experiments, cryo system for g-2 and Mu2e, and power supplies for some beamline components

• 80’ x 80’ high-bay with 30 T crane

• internal loading dock • floor stable, load-

bearing to 700 T• good temperature

control• 70’ x 70’ low-bay for

staging, assembly, control room

• Includes extension of existing communication duct to replace duct which is interrupted during tunnel excavation

• Total cost expected to be $9M, costing is mature

Beamline enclosure GPP Civil construction of enclosures for M4 and

g-2 extraction lines• Delivery Ring to Mu2e – M4: 10’ wide x 8’

high concrete box type enclosure with 16’ equivalent earth shielding. Base slab at El:728’-8”.

• M4 line to g-2: 8’wide x 8’ high enclosure. Base slab slopes from El: 728’-8” to El 734’-6”.

• Beamline power supplies from AP-30, g-2 and Mu2e. Low Conductivity Water extended from Delivery Ring.

• Includes lighting, grounding, electrical power distribution, cable tray, fire detection, life safety egress, drainage and sumps. Installs beam abort.

• Current estimate $9.2M, could increase as plans become better defined (beamline design still in progress)

A-0 Cooling Pond Civil construction to renew the A-0

pond heat rejection capacity and provide capacity for the 13.8 kv feeder from Master Substation to F-3 Switch.• A-0 Pond – Restore pond depth to

the original profile; replace pond pumps and intake; relocate and replace discharge.

• 13.8 KV Electrical Upgrade – Install new feeder (24B) in existing Main Ring duct bank from Master Substation to the F-3 Switch

9

• Costing still in progress

Site prep GPP• Originally (early 2012) the Site Prep GPP included:

1. removal of an old spoils pile2. relocation of Kautz Rd3. installation of an additional power feeder

• Issues since then: items 1) and 2) above need to be accelerated in order to accommodate

accelerated Mu2e civil construction schedule items 1) and 2) above total ~$2M, not in lab's FY14 budget unclear feeder is needed: the estimated (g-2)+Mu2e needs are on the edge

of current capabilities and carry a large uncertainty

• Current plan    eliminate this GPP? move items 1) and 2) to Mu2e project

• Mu2e funding profile can accommodate this• will identify scope to swap out of Mu2e

revisit need for feeder once beamline designs are more mature and power needs can be estimated more accurately• if needed, would require funding in FY16-17 to be ready for Mu2e

solenoid commissioning in late FY1710

Cryo AIP

Compressor and refrigeration systems g-2 and Mu2e cryogenic distribution system

Reuse Tevatron compressors at A0• Compressed He line from A0 to MC-1 building

Refurbish Tevatron refrigeration components to be housed in MC-1 building• 4 refrigerators to support simultaneous steady-

state operation of both g-2 and Mu2e Cold lines extending to both experimental

halls

• Total cost $9.8M, contingency is well understood

Recycler AIP

Allows 8 GeV proton beam to be rebunched in the Recycler and extracted to the P1 line for transport to experimental areas• 2.5 MHz RF for re-bunching beam• Extraction kickers• Beamline connection from Recycler to P1 line• MI52 building extension for kickers (civil – move to separate FESS

project?)

13

RF cavity production• Cavities must have active cooling• Reuse ferrites from MI coalescing

cavities• Labor intensive• 7 RF systems (cavities + PA’s) for

Recycler• 2 cavities for Mu2e to be installed
