Points to be covered High Energy Physics – Excitement NOW ATLAS Upgrade R&D Program
Based on an increase by a factor of 10 in luminosity to extend the physic reach
How the U.S. participates Our view of the priority of this work
How universities fit in There is a large spectrum of abilities in different universities –
probably that is good What sets the scale for the participation How infrastructure is critical for success
DOE and NSF High Energy Physics University Grant Program Subpanel (UGPS) January 8, 2007 SLAC3
My Personal View High Energy Physics in my career has never been as
exciting as now There are big discoveries on the horizon
Electroweak symmetry breaking: Higgs? SUSY? Tevatron? If not: hopefully at the LHC if not with ILC needed to make the detailed measurements
Dark Matter? Dark Energy??? CP Violation in the neutrino sector? Extra Dimensions?
However, the funding for our field is close to flat-flat and everyone is struggling – New York Times: Jan. 8, 2007
DOE and NSF High Energy Physics University Grant Program Subpanel (UGPS) January 8, 2007 SLAC4
Although we expect to make discoveries and a lot of measurements at the LHC, plans have started for upgrading LHC
Higher energy difficult without major R&D development Higher luminosity (1035 cm-2 s-1) seems feasible
Some studies have been done to evaluate increased physics potential:
Very prelim. studies also suggest it is possible with 3000 fb-1 per experiment to make the first measurement of the Higgs self-coupling via HH production
Detector R&D is getting underway, to be ready for ~ 2010-2014 Construction Period For ATLAS the entire Inner Detector would be replaced as well as the Liquid Argon
on-detector electronics

LHC Upgrade Parameters are NOT Set
The 12.5 ns scenario seems to have left the scene (for how long?)
The 75 ns scenario pushed backwards Two new scenarios appears in the front
50 ns long bunch 340 events/bunch crossing (at start of fill) - likely
25 ns high ß 223-296 evt/bc
Keep doors open and remember that we do not know (yet) tot at LHC .
(some theoreticians say anywhere between 100 and 150 mbarn!)

WBS 4.1.1.2 Strip Detectors
Beginning to develop a detailed understanding of the behavior of n-on-p detectors. Curve is a summary of some measurements, symbols are predictions from paper by Bruzzi, Sadrozinski, and Seiden. Unlike p-on-n detectors, charge collection does not require very large voltages at large fluences. Region of good charge collection matches well our plan to keep the strip detectors at radii larger than 25 cm.

U.S. ATLAS has put Priority on Upgrade R&D
We still need to complete the construction, commissioning, and pre-operations of ATLAS
We have several items on the critical path and need to focus resources to accomplish our goals
However, we believe that the U.S. can make seminal intellectual contributions to the Upgrade R&D and need to do work in order to establish this
Key technical personnel may be finished with their work on construction, commissioning and pre-operations and the Upgrade R&D provides a way to engage them so they do not drift on to other projects
We hope this support will continue through the Upgrade Construction. This work is a partnership between the U.S. National Laboratories and the
universities. Each provides crucial contributions The Labs typically have more of a critical mass of technical people to
address issues in a more system-wide manner Example of the Low Voltage Liquid Argon Power Supplies
Universities, besides providing intellectual input, also have students and postdocs who can carry out a focused part of the R&D

Upgrade Construction Planning in ATLAS
The entire tracker must be replaced Technologies which now work at inner radii will
work at outer radii – but new technologies must be developed for the inner radii
For example, 3-D pixels Cost estimates for a new pixel layer are
expected to be ~34 MCHF New silicon strip layers ~105 MCHF (130 m2)
Calorimetry ~15-32 MCHF Muon System and Trigger/DAQ 20-30 MCHF An Upgrade Project Office has been established
to insure that R&D work is coherent and services are considered from the beginning.
DOE and NSF High Energy Physics University Grant Program Subpanel (UGPS) January 8, 2007 SLAC27
Upgrade Construction Given to P5 in March 2006
ATLAS has made an estimate for the cost of the upgraded detectors We have calculated the U.S. share based on the current $/CHF ratio, the
experience with CERN cost estimates and U.S. accounting, plus some escalation
There are larger error bars on these numbers but they were presented to P5 and (hopefully will be included) in agency planning

ILC Detector R&D I chaired the DOE/NSF Panel for ILC Detector R&D for a couple of
years. It was a great learning experience for the committee However, I believe the amount of money available was not enough
to carry out serious detector R&D Even though the committee had discretion to recommend what it
wanted and although the committee chose the most relevant and time critical topics, generally there was a request and a recommendation for some M&S, a grad student and perhaps a post doc
In contrast, with about $3M/year, the U.S. ATLAS choice of funding Upgrade R&D at that level has already produced some good results
As far as the synergy of ILC and LHC R&D, some groups will try to find the synergy but it does not have to follow logically

Conclusions We have not dealt with the real issues which need to be addressed in the future:
How many university groups need to be supported in HEP How much support should they get to be effective What is the role of the university group and the national labs – (we hope a
partnership) Rather we have described a collaborative system built on needs and capabilities –
market driven by the needs of the ATLAS upgrade and the capabilities of the group The ATLAS upgrade is moving ahead with Upgrade R&D U.S. university groups are contributing to this by participating and often leading
R&D proposals where they can make a unique contribution Based on their contribution, the U.S. ATLAS Research Program offers some
support of infrastructure Even in the Physics Analysis, it is difficult for a single university group to have a
mastery of all the software and data bases needed for analysis. Still there is a WIDE variation in the capabilities of various university groups
In the past, a lot of infrastructure support was in the Core Research Program Most groups are asked to choose between technical infrastructure and a post doc
or student and we know how they choose Some have sufficient resources to tackle state of the art problems
Univ. X has a state of the art silicon production facility; univ. Y has good electrical engineers
Others are in the model of a professor with a good idea and students

Critical Issues from Mike Tuts at your September 2006 meeting (still critical!)
What are the critical issues threatening the achievements of the project goals? Funding
Currently ~flat in the out years – some relief in profile starting in 2008 promised in Oct. 2006! P5 quote “The level of support for this program should not be allowed to erode through inflation”
Travel/COLA costs are higher for CERN Fall 2005 US ATLAS survey indicates ~x2 over domestic program ~ $2M/yr problem for Core program
Upgrade funding (not just R&D) needs to be in US planning efforts Has been presented to P5, so may be in there now
Infrastructure How do we preserve the technical infrastructure for the upgrade?
Upgrade R&D RP can help, but year-to-year funding makes it difficult to plan Is it enough?
Collaborative tools Not yet taken seriously at CERN
Even good audio is a problem Have a plan (see RTAG 12 report for example), but no funding
Experiments are trying to help We have a couple of well outfitted rooms, but need more
Office space Rapidly becoming an issue
Not a threat, but we need to gain experience with our physics analysis support model – good so far!
