ATLAS Upgrade Organization
Main Efforts now are:
Establish working groups to coordinate the R&D
Upgrade Steering Group
Upgrade Project Office
Francesco Lanni has taken the lead in defining and developing cost estimates for the U.S. LAr Upgrade program U.S. people
Additional persons invited for special discussions.
Some permanent members still missing. (Tile, Muons, Trigger)
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.
Solid model rendering of a stave constructed using an 8mm diameter aluminum tube that has been reformed to enhance thermal transport area.
View of overall stave depicting strip detectors, hybrids and chips. The assembly comprises 15 strip detectors with a length of 993.5mm.

NSF Guidance Note:
The NSF funding numbers above are shown on a fiscal year monthly
spending plan. NSF funding breakdown: 8/1/04 = 3.5M; 5/1/05 = 5.25M;
2/1/06 = 6.75M; 11/1/06 = 9M; 11/1/07 = 9M
Average of the 12 university budgets ~$125k
Currently 12 university groups are working on the Upgrade R&D. We expect several more to join in the next year and most of the 37 university groups to contribute to Upgrade Construction.
Note these are universities plus labs – but % is probably similar in both. The Core Research Program is CRUCIAL for M&O and Upgrade R&D
