Introduction
• This is primarily a technical review and we welcome your
comments, suggestions and insights.
• We are not the MECO Collaboration. We stand on the
shoulders of MECO and many of our collaborators come from
MECO, but many of us were not on MECO.
• We are currently in an assimilation phase where we are
trying to take ownership of the vast amount of technical
information that MECO produced over many years.
• We are more mature technically than most experiments at
this stage, but the Collaboration is still in its infancy and the
Project is embryonic.

Scope (cont.)
• New detector hall
• New beamline from pbar to detector hall that
provides slow extracted beam with the
appropriate beam structure
• Extinction channel
• Simulations to support design
• ES&H is important. We will do this safely.
• QA/QC is important.
• Build it all within baselined cost.
• Build it on baselined schedule.

Detector Hall and Civil
Construction
FESS has done a significant amount of work
preparing a preliminary design and cost estimate.
 Beamline travels under creek in attempt to
minimize wetlands issues.
 Includes plan for routing services to building
(electrical, cryo, water, …).
 Includes shielding on top of beamline and building.
 Building depth is driving the cost.
We have to better understand our requirements and be
prepared to make tradeoffs as part of the value engineering
process.

Proton Beam
• Use protons from booster
while MI is ramping.
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
 No impact on neutrino program.
 6 booster batches, each ~4x1012
protons, are delivered to the accumulator every 1.33 s.
 ~ 3.6x1020 pot/yr.
 Requires 15 Hz booster operation.
• Use the Debuncher and accumulator rings to bunch the beam.
• Require proton extinction of 10-9 between bunches
 Pulsed beam and extinction reduce prompt backgrounds.

Superconducting Solenoids
Critical path. Most complex and expensive deliverable.
• Production solenoid contains
proton target, heat shield,
high gradient field to capture
pions and muons.
• Transport solenoid contains two
curved sections and a large gradient straight section.
Magnetic channel that transports muons to stopping target.
• Detector Solenoid houses stopping target and detector
elements and requires high field uniformity in detector region.

Tracker
•
The Tracker must provide precise momentum
measurements to separate signal events from
DIOs in a 1 T field.
•
The end point energy for DIO electrons coincides with the
conversion signal, the end point spectrum falls as E5, thus the level
of DIO background is sensitive to the resolution function.
•
The resolution is dominated by multiple scattering, thus material
must be kept to a minimum
•
Tracker must operate with high efficiency in a high rate
environment
•
Robust pattern recognition required to eliminate tails from misreconstructed events.

R. Ray - Director's Review of mu2e
11
Electromagnetic Calorimeter
• Calorimeter serves several purposes
 Used to form trigger
 Starts data acquisition.
 Provides reference time for tracker drift tubes
 Provides independent energy measurement
 Particle ID
• Must operate in high rate environment
• Photodetector must operate in 1 T magnetic field.

R. Ray - Director's Review of mu2e
12
Cosmic Ray Shield
• Cosmic rays have been close to the limiting factor
in previous experiments. Pulsed beam, active and
passive shielding are used to reduce this
background.
• Large area detector requires cost effective
technology.
• Total rejection of 10-4 required for combination of
active and passive shielding.
• Cosmic ray background can be measured off-spill.

R. Ray - Director's Review of mu2e
13
Simulations
We need a reliable simulations package to validate
designs, evaluate tradeoffs and optimize costs.
• We have the MECO MC and can run it, make plots, etc.,
but we don’t fully understand what is in it, the beamline
is different, it is written in Fortran, etc.
• We want to convert the MECO MC to a mu2e MC using
object oriented code that we fully understand and
document.
• Talking to CD about help in this effort.

ES&H Issues
This list is surely not exhaustive:
• Fire, ionizing radiation, RF radiation, oxygen
deficiency and electrical hazards are all relevant
safety concerns for mu2e.
• Environmental issues include disturbance of
wetlands and groundwater activation.
• These are the standard issues that we are used to
dealing with at Fermilab. Most are covered by
categorical exclusion.
• We will prepare a Preliminary Safety Assessment
Document (PSAD) for CD1.

17
Risks
• The greatest cost and schedule risk is the
solenoid system.
 Considerable resources will have to be devoted to design,
costing, procurement, QA/QC and integration to mitigate
risk.
• Technical risk associated with extinction.
 We must have the beamline done early so that extinction
can be tested and leave us with time to react.
• Technical risk associated with heat shield
designed for safe heat/energy loads in the
production solenoid.
 Must be designed for the maximum potential beam flux
Sept. 26, 2008
R. Ray - Director's Review of mu2e
18
Risks (cont.)
• Detector performance.
 Can only be studied with extensive prototypes, system
tests, cosmic rays and beam tests. Can’t reconstruct
DIO electrons until solenoid system is installed and
commissioned.
• Slow extracted beam
 Boomerang scheme has yet to be worked out in detail.
Many uncertainties.

Cost Estimate
• Cost estimates at this early stage are rarely good
to better than a factor of 2. History bears this
out.
• Because of the extensive work on MECO we are
better off than the typical project at this stage in
many areas, but not all.
Sept. 26, 2008
R. Ray - Director's Review of mu2e
20
Cost Estimate Strategy
for the Proposal
• Use numbers from MECO where possible
 Add 4 years of escalation at 3.5% per year
 Use Wojciki Review Committee recommendation
• "The RSVP Project Office advocates an overall project
contingency of 45% based on the community's
experience-base with large complex detector projects.
The committee agrees that at least 45% is appropriate
for the project at this stage."
 Many parts of the MECO detector were understood to a
level that would justify a smaller contingency than 45%,
but we think this approach is adequate and appropriate
for a proposal.

21
Cost Estimate Strategy (cont.)
• FESS did cost estimate on detector hall and
beamline civil work. Use their contingency.
• AD did cost estimate on beamline. Use their
contingency.
• Use Project management costs from NOvA. Use
their contingency.

Cost - Longer Term Strategy
• We will develop a resource loaded cost and
schedule from the bottom up.
 L2, L3 managers will develop a cost and schedule that
they must own and be responsible for. They will use the
MECO WBS as a guide, where relevant, but if they
prefer to do things a different way and can convince us
that their plan makes sense, we will go in a different
direction.
• We will use OpenPlan, COBRA, WelcomeRisk, etc.
as our basic set of scheduling, budget and
reporting tools.
