Measurement of the Depolarization Parameter in Elastic Proton Proton Scattering at 3 and 6-GeV/c
Results are presented from an experiment designed to make the first systematic study of the depolarization parameter in elastic proton--proton scattering at high energies. Measurements were made at 3.0 and 6.0 GeV/c at abs. value t values extending to 1.7 (GeV/c)2 at the higher momentum. A high- intensity unpolarized proton beam was incident on a polarized proton target and the polarization of the elastically scattered recoil protons was determined with a carbon analyzer. The results are discussed in the framework of optical and exchange models.

Polarization in p-p elastic scattering at large four-momentum transfers
New results are presented from the continuation of an experiment designed to study the polarization in elastic p-p scattering at large four- momentum transfers. A high intensity unpolarized proton beam of momentum 12.3 GeV/c was incident on a propanediol polarized porton target and both final-state protons were detected and momentum analyzed in multiwire proportional chamber spectrometers. The measurements spanned the t range 1.5 < absolute t < 6.2 (GeV/ c)$sup 2$. The results are discussed in the framework of optical, exchange, and parton models. (AIP)

Monolithic CMOS Pixel Detectors for ILC Vertex Detection
A CMOS pixel vertex detector suited for use at the International Linear Collider (ILC) is proposed. The proposed detector consists of 50µm ◊ 50µm macropixels, each with integrated bunch clock memory, on top of 5µm ◊ 5µm micropixels that record amplitude information. The micropixels integrate over all bunch crossing in a train. Using the time recorded by the macropixels, the fine position measurements made in the micropixels can be associated to only a few of the 3000 bunch crossings in a bunch train.

Status of the Compact Muon Solenoid Detector at the Large Hadron Collider
The Compact Muon Solenoid (CMS) detector is being constructed at the Large Hadron Collider (LHC) at CERN for the purpose of exploring new physics in proton‐proton collisions at 14 TeV. The detector is to be designed, constructed and commissioned in time for the start of the LHC in April 2007. This article summarizes the current status of the detector and foreseen program for completion.

Monolithic CMOS pixel detector for international linear collider vertex detection
A monolithic CMS pixel detector is under development for an ILC experiment. This chronopixel array provides a time stamp resolution of one bunch crossing, a critical feature for background suppression. The status of this effort is summarized.

Data preservation and long term accessibility in high energy physics at the 2nd International Conference on Frontiers in Diagnostic Technologies in Frascati, Italy
Abstract Recently there have been significant developments in high energy physics (HEP) data preservation projects while other large data volume experiments are now also facing for the first time insuring the long term accessibility of their data. In this presentation, the status of advanced HEP data preservation projects as well as the challenges and plans for projects newly facing this task will be presented. The continuing efforts to develop guidelines and tools, the justifications for these efforts and the state of discussions of more open accessibility of the data and how this is foreseen to be managed are included.

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
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.
