Progress with the single-sided module prototypes for the ATLAS tracker upgrade stave
/ Allport, P P (Liverpool U.) ; O'Shea, V (Glasgow U.) ; Wiik, L (Brookhaven) ; Dressnandt, N (Pennsylvania U.) ; Matheson, J (Rutherford) ; Li, Z (Brookhaven) ; Viehhauser, G (Oxford U.) ; Gallop, B (Rutherford) ; Jones, T J (Liverpool U.) ; Dwuznik, M (AGH-UST, Cracow) et al.
The ATLAS experiment is preparing for the planned luminosity upgrade of the LHC (the super-luminous LHC or sLHC) with a programme of development for tracking able to withstand an order of greater magnitude radiation fluence and much greater hit occupancy rates than the current detector. This has led to the concept of an all-silicon tracker with an enhanced performance pixel-based inner region and short-strips for much of the higher radii. [...]

Progress on DC-DC Converters for a Silicon Tracker for the sLHC Upgrade
/ Dhawan, S (Yale U.) ; Baker, O (Yale U.) ; Chen, H (Brookhaven) ; Khanna, R (National Semiconductor Corp, Richardson) ; Kierstead, J (Brookhaven) ; Lanni, F (Brookhaven) ; Lynn, D (Brookhaven) ; Musso, C (New York U.) ; Rescia, S (Brookhaven) ; Smith, H (Yale U.) et al.
There is a need for DC-DC converters which can operate in the extremely harsh environment of the sLHC Si Tracker. The environment requires radiation qualification to a total ionizing radiation dose of 50 Mrad and a displacement damage fluence of 5 x 1014 /cm2 of 1 MeV equivalent neutrons. [...]

Radiation Resistant DC- DC Power Conversion with Voltage Ratios > 10 Capable of Operating in High Magnetic Field for LHC Upgrade Detectors
/ Dhawan, S (Yale U.) ; Baker, O (Yale U.) ; Khanna, R (Nat. Semiconductor Corp., Richardson) ; Kierstead, J (Brookhaven) ; Lynn, D (Brookhaven) ; Mincer, A (New York U.) ; Musso, C (New York U.) ; Rescia, S (Brookhaven) ; Smith, H (Yale U.) ; Tipton, P (Yale U.) et al.
Commercial power converters that have voltage ratios greater than ten and are capable of running near the LHC collision region would increase the efficiency of the power distribution system of the ATLAS Silicon Tracker high luminosity upgrade. The devices must operate in a high magnetic field (2 T) and be radiation hard to ~50-100 Mrad and ~1015 Neq/cm2. [...]

High Radiation Resistant DC-DC Converter Regulators for use in Magnetic fields for LHC High Luminosity Silicon Trackers
/ Dhawan, S (Yale Univ., New Haven, CT) ; Baker, O (Yale Univ., New Haven, CT) ; Tipton, P (Yale Univ., New Haven, CT) ; Kierstead, J (Brookhaven Nat. Lab., Upton, NY) ; Lynn, D (Brookhaven Nat. Lab., Upton, NY) ; rescia, S (Brookhaven Nat. Lab., Upton, NY) ; Weber, M (Rutheford Appleton Lab., Chilton)
For more efficient power transport to the electronics embedded inside large colliding beam detectors, we explore the feasibility of supplying higher DC voltage and using local DC-DC conversion to 1.3 V (or lower, depending upon on the lithography of the embedded electronics) using switch mode regulators located very close to the front end electronics. These devices will be exposed to high radiation and high magnetic fields, 10 – 100 Mrads and 2 - 4 Tesla at the SLHC..

Ideas on DC-DC Converters for Delivery of Low Voltage and High Currents for the SLHC / ILC Detector Electronics in Magnetic field and Radiation environments
/ Dhawan, Satish ; Lynn, D ; Neal, H ; Sumner, R ; Weber, M ; Weber, R
For more efficient power transport to the electronics embedded inside large colliding beam detectors, we explore the feasibility of supplying 48 Volts DC and using local DCDC conversion to 2 V (or lower, depending upon on the lithography of the embedded electronics) using switch mode regulators located very close to the front end electronics. These devices will be exposed to high radiation and high magnetic fields, 10 – 100 Mrads and 2 - 4 Tesla at the SLHC, and 20 Krads and 6 Tesla at the ILC..

Energy Resolution of the Barrel of the CMS Electromagnetic Calorimeter
/ CMS Collaboration
The energy resolution of the barrel part of the CMS Electromagnetic Calorimeter has been studied using electrons of 20 to 250 GeV in a test beam. The incident electron's energy was reconstructed by summing the energy measured in arrays of 3x3 or 5x5 channels. [...]
