SNUMI - Phase 1

SNUMI is sometimes referred to as the “McGinnis Plan”. The intention is to increase the power on the NuMI Neutrino target in the assumed absence of the Proton Driver. SNUMI utilizes modifications to existing Fermilab facilities after the completion of collider physics at the end of FY09.

SNUMI is planned to occur in two phases. The first phase will use the Recycler Ring to slip stack 12 Booster batches of protons into six slots and then single turn transfer them into the Main Injector. The Main Injector will then spend minimal time at 8 GeV and the Main Injector cycle is reduced to about 1.33 seconds. The power on the NuMI Target will then be about 700 kilowatts. A second injection line from the Booster to FMI 8 GeV line will be constructed for injection into the Recycler, while preserving the existing injection line to the FMI.


SNUMI - Phase 2

Phase 2 involves the use of the accumulator ring to coalesce multiple Booster batches (say 3) into a single batch and then load them ‘box-car’ style into the recycler during the FMI acceleration ramp. This requires the construction of two new transfer lines called AP-4 and AP-5. AP-4 parallels the historic route of the original AP-4 abandoned and destroyed when the Booster to FMI 8 GeV line was constructed in 1996. AP-5 is a new line that takes extracted protons from under AP-10 Building around a 100 degree arc back into the 8 GeV line just upstream of the access hatch near 817.

AP-4/AP-5 – Accumulator Connections

For AP-4 the plan is to extract from the Booster connection enclosure using a pipe drilled through a longitudinal vertical side wall, with a beam line elevation held at 726.582’ which is the 8 GeV line elevation before the main downbend. That elevation brings the beam into the accumulator enclosure just above the floor level of 726’. Beamline designers now believe it may be necessary to enter above the debuncher, elevation, cross over to the accumulator, and come down to the accumulator injection orbit. AP-5 is a steady downslope carrying the beam from the accumulator elevation a few feet above the 726’ floor to the 8 GeV line elevation a few feet over the 712’ floor.


Phase 2 – Accumulator Connections (Cont.)

The new enclosures form a rough x. It is speculated that a common elevation might be achieved at the crossing. The existing 808 exit stairs could be incorporated. FESS will need to consider life safety requirements, exiting, etc. for the new enclosures. Near the Booster end (upstream AP-4) there is a very crowded utility region with at least two primary corridors. To build the 8 GeV connection job 6-6-12 earth retention systems were installed to keep the excavation narrow and limit the utility bridge support lengths. It is supposed that the upstream end of the proposed AP-4 would need a similar excavation technique, although perhaps most of the other three arms of the X might be open cut. The following sketch is a rough suggestion of the AP-4 and AP-5 location.


Phase 2 – Accumulator Connections (Sketch)


Phase 2 – Accumulator Connections (Utilities)

The following picture was taken during the 6-6-12 excavation, and the utility support bridges are plainly visible, and the route of the proposed AP-4 is right into the picture.


FESS Deliverables

A Director’s Review of SNUMI is scheduled for mid November 2006. Phase 1 work should be pretty well developed for this review. For the civil work that would include fairly good definitions of the work and cost and schedule estimates, including the impacts on machine operations during phase 1 civil construction tasks. For the review, phase 2 work would possibly be less well developed, although sufficient development should have occurred to demonstrate the possibility and rough cost estimates available, with whatever caveats the state of the work at the time would require.


DOE Space Offsets

The SNuMI Project must balance new construction with elimination of excess space, in keeping with the DOE SC Space Management requirements. This would be accomplished by phases:

Phase 1 new facilities: MI14 (75’ x 30’) 2250 sf MI39 (50’ x 30’) 1500 sf MI 60 anode supply room (10’ x 25’) 250 sf 4000 sf

Phase 2 new facilities: AP4 enclosure (8’ x 700’ long) 5600 sf AP5 enclosure (8’ x 300’ long) 2400 sf 8000 sf Planning for this preliminarily should include allowance for demolition of on-site space at a cost of $80/sf of straight construction cost. Therefore, the cost by phase would be:

Phase 1: 4000 sf @ $80/sf = $320,000 Phase 2: 8000 sf @ $80/sf = $640,000

SciBooNE Civil Construction

SciBooNE is an experiment that is moving the “SciBar” Detector from Japan to the United States for a test runbefore returning it to Japan for installation at JPARC.

The detector is to be installed 100 meters downstream ofthe MiniBooNE Target at MI-12.

The excavation for the detector enclosure is starting in theimmediate future; Notice to Proceed was gi8ven to thecontractor last Tuesday, Sept 19th, and the contract is forbeneficial occupancy in 90 days, on December 11th.

The work is shown in the following two slides.

SNUMI MI-14 Kicker Building

A new kicker building (MI-14) is required approximately at cell boundary 104. The size of the kicker building is specified as 30’x50’ and is assumed to be a clone of the kicker building F17 built for the Main Injector transfers into the Tevatron. It is possible, however, that additional space for the beamline power supplies for 8 GeV beam to Recycler Beam transfer will also need to be located here, and an additional 25’ (making 30’x75’) may be required. A transformer, duct banks for power and communications, and cooling piping, etc., may also be necessary, along with fire suppression, lights, HVAC, etc.


MI-39 Kicker Building at MI-40

The second requirement is another 30’x50’ kicker building clone of F-17 tentatively called MI-39. This was first proposed on the inside toe (or shoulder of the berm if the wetlands were too close) of the berm near quad 400. After a site visit, a better choice of location was thought possible. The location of MI-39 is shown in the following sketch. Power, cooling, and communications ducts will be required. Further refinements of the location were made after visits to the site located additional transformers not shown on the site drawings used as backgrounds for this work. The proposed MI-39 kicker building still fits, although it is tighter.


F17 is a model for these Buildings

These drawings are taken fromProject 6-6-8A


4th Anode Supply Room at MI-60

The third phase 1 requirement is a fourth anode supply room at MI-60. Six more rf systems (2 more in the FMI, and 4 in the recycler) are to be added, increasing the demand by one third, raising the number of anode supplies from three to four. The west wall of MI-60 low bay is pretty crowded and it may be necessary to choose a spot that requires the construction of a blast/fire wall near or inside MI-60.

Buss Bar Insertion at MI-60

The fourth phase 1 item is a study of the possibility of creating roof hatches in the MI-60 rf low bay area to allow the insertion of additional buss bar packages down existing extra penetrations. At least at one location proposed it is likely that there is interference with the MI-60 high bay east wall. The location of the empty penetrations to house the proposed additional buss bars was translated unto a drawing for FESS to consider interferences at the exact proposed locations. This was done 9/8/06, and in both locations a fundamental interference with a “roof purlin beam” exists. This is seen on the next drawing. While possible to add additional purlin beams, and box out an opening for the passage of the buss bar, at the location opposite the high bay buss the bar would hit the east wall of the high bay as well. The initial recommendation is to fabricate the buss bar from shorter sections without removing fundamental interferences.


Additional Cooling Pond at MI-60 Ponds A/B

The first phase 2 study item is the provision of additional pond cooling water acreage. Two possibilities were mentioned during the discussion; the first created an additional return leg in the ponds A/B system called pond X (making an “E” rather than a “C”). A second possibility would extend pond supply and return pipes from the F-sector Tevatron ponds over to the MI-60 pond water heat exchangers. AD/Mechanical Support has been evaluating the cooling capacity of the MI-Ponds as-built. With information supplied by AD/Mechanical Support, it is now known that the enlarged cooling pond will not be necessary to support Phase 1 of SNUMI. Thus, the “Pond X” investigations are now designated Phase 2 work for FESS.


Phase 2 – AP-4 Connection - 8 GeV Exit Point

The exit point from the 8 GeV enclosure is in the middle of the upper vertical wall over the sump alcove on the right of the following picture.


Phase 2 – AP-4 Connection - 8 GeV Exit Point

There is one possible interference from job 6-6-12 with the proposed extraction; a duct bank was built over the sump alcove and is shown in the following picture. The elevation of this duct bank needs to be determined from the 6-6-12 as-builts to see if the proposed extraction pipe will fit under the duct bank, or if the duct bank must be relocated.
