Phase 1 Elements of Construction
A discussion of the development of civil definitions and preliminary cost
and schedule estimates was held between Elaine McCluskey and Dixon
Bogert on August 11, 2006.The basic outline was written down by Dixon
on the Engineering Note shown below.
SNUMI is planned to occur in two phases. The
first phase, for which the items are identified
with φ1 in the left margin, is required for the use
of 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 is then about 700 kilowatts.

MI-14(?) Kicker Building at MI-10
First, a new kicker building (MI-14?) is required approximately
at cell boundary 104. This is probably best located on the
inside of the FMI berm immediately adjacent to the “peanut
vault” called MI-11. 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. Duct banks for power and communications,
and cooling piping, etc., may also be necessary, along with fire
suppression, lights, HVAC, etc.

Proposed MI-14 Site Near MI-10
During the week FESS developed a detailed site plan for the
MI-14 kicker building, based upon discussions with staff
from AD/Electrical Support.
To avoid setting the MI-14 building in the Indian Creek flood
plain, the proposed building was turned around with entrance from
the top of the FMI shielding berm. Discussions included the
power required for the kickers, and the power required if an
addition to house beamline power supplies is required.
In this orientation, the kicker ducts cross under the proposed
building.
Shielding sections (not shown) were also made.

This week further refinements were made of the location plan, and
sections of MI-14 and MI39 were prepared to show elevations and
approximate kicker penetration routings. Straight penetrations for
fluorinert and cooling water are not yet shown.
Cost estimates were begun.
FESS and AD/Elect Support needs information about the
beamline power supplies, controls, etc.

MI-39(?) Kicker Building at MI-40
With respect to the second new kicker building that is required near MI-40
[MI-39(?)] this is what FESS was told:
The second requirement is another 30’x50’ kicker building clone of F-17
tentatively called MI-39 located on the inside toe (or shoulder of the berm if
the wetlands are too close) of the berm near quad 400. Access must be
provided, perhaps using a modification of the existing access ramp to the
berm top at MI-40. The location of MI-39 is shown in the following sketch.
Power and communications ducts will be required, and possibly a
transformer and switch.
After a site visit, a better choice of location was thought possible.

MI-39(?) Location Near MI-40
This location
was suggested in
the original memo.
It is in wetlands,
and access is poor.
A possibly better
choice is shown
next, but the
cable runs will be
longer, although
acceptable (<200’).

Proposed MI-39 Site Near MI-40
During the week FESS developed a detailed site plan for the
MI-39 kicker building, based upon discussions with staff
from AD/Electrical Support.
The proposed building was set as shown last week outside of
the FMI shielding berm. Discussions included the
power required for the kickers.
In this orientation, the kicker ducts enter the FMI berm
directly from the back of the building.

used as backgrounds for this work. The proposed MI-39 kicker
building still fits, although it is tighter.

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
picking a spot that will be ‘safe’ in the event of a
transformer blast/fire and allow room for feeder
access to a new switch and the 4th anode supply
transformer is tricky. It may be necessary to choose a
spot that requires the construction of a blast/fire wall
near or inside MI-60.

4th Anode Supply Room Location at MI-60
FESS further developed the concept of locating the additional
anode supply room in the area immediately north of the MI-60
high bay. A blast/fire wall was developed that could be placed
immediately north of the high bay wall and made part of
the MI-60 high bay wall.

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 fifth phase 1 study item is the provision of additional pond
cooling water acreage; this may not be absolutely necessary until
phase 2. 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 Fsector 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 – Accumulator Connections
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. 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’. 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. This study 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 (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.

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.

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.

Cost and schedule estimates are being prepared now
for the November Review. In advance of the Phase 1
estimates from FESS, Dixon made some “physicist
quality” estimates that have been inserted in the
Recycler cost and schedule tables as place holders.

FESS forwarded to SNUMI Management
comments on 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 onsite 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
