Møller polarimetry with atomic hydrogen targets
(Springer-Verlag; Società Italiana di Fisica, Springer-Verlag, 2005-02)
A novel proposal of using polarized atomic hydrogen gas, stored in an ultra-cold magnetic trap, as the target for electron beam polarimetry based on Møller scattering is discussed. Such a target of practically 100% polarized ...
Supersymmetry parameter analysis: SPA convention and project
(Springer-Verlag, 2006-04)
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when higher-order corrections are ...
The startup of Run II: Status of Tevatron, CDF, and DØ
(Springer-Verlag; Società Italiana di Fisica, Springer-Verlag, 2004-07)
I briefly summarize the current status of Tevatron Run II, and highlight a few preliminary results from the CDF and DØ experiments.
Ablation plasma ion implantation using a dc power supply
(Springer-Verlag, 2004-09)
Experiments are reported in which ablation plasma ion implantation (APII) has been demonstrated using a dc power supply. The ability to use a dc power supply for APII has been accomplished by using a perpendicular orientation ...
Hard X-ray generation from solids driven by relativistic intensity in the lambda-cubed regime
(Springer-Verlag, 2006-04)
Interaction of relativistic intensity laser pulses encompassed at focus by a volume of a few wavelengths cubed with solids is examined. Spectroscopy of hard X-rays of several metallic targets, including Cu, Ge, Mo, Ag, and ...
Generation and measurement of >10 8 intensity contrast ratio in a relativistic kHz chirped-pulse amplified laser
(Springer-Verlag, 2005-08)
We report on the generation and measurement of a > 10 8 contrast ratio between main pulse and amplified spontaneous emission (ASE) from a relativistic kHz chirped-pulse amplified laser. We have enhanced the ASE contrast ...
On the design of experiments for the study of relativistic nonlinear optics in the limit of single-cycle pulse duration and single-wavelength spot size
(Nauka/Interperiodica; MAIK "Nauka/Interperiodica" ; Springer Science+Business Media, 2002-01)
We propose a set of experiments with the aim of studying for the first time relativistic nonlinear optics in the fundamental limits of single-cycle pulse duration and single-wavelength spot size. The laser system that makes ...
Phase-matched enhancements of high-harmonic soft X-rays by adaptive wave-front control with a genetic algorithm
(Springer-Verlag, 2004-02)
We demonstrate the enhancement of high-harmonic soft-X-ray generation by adaptive wave-front control of a 745-nm Ti:sapphire laser by use of a 59-channel membrane deformable mirror, combined with a genetic algorithm, for ...
Characterization of focal field formed by a large numerical aperture paraboloidal mirror and generation of ultra-high intensity (10 22 W/cm 2 )
(Springer-Verlag, 2005-06)
We describe a method to measure the aberrations of a high numerical aperture off-axis paraboloid and correct for the aberrations using adaptive optics. It is then shown that the characterized aberrations can be used to ...
