Coincidence gamma–gamma spectroscopy system for instrumental neutron activation analysis

A flexible facility for γ–γ coincidence spectroscopy with two HPGe detectors based on NIM spectrometric modules in connection with VME or CAMAC data acquisition systems is described. First results of its application for Coincidence Instrumental Neutron Activation Analysis (CINAA) are presented.

Charge sharing studies with a Medipix1 pixel device

Abstract The Medipix1 chip is a prototype (digital) CMOS imaging chip that emerged from particle detection in high energy physics experiments. It was designed at CERN following specifications from the Medipix1 Collaboration. This contribution aims at demonstrating the applicability of Medipix1 Si and GaAs pixel devices for alpha and X-ray particle detection. A study of “charge sharing” between pixels and test of “spatial resolution” using narrow beam and “edge” image contrast was performed. For photons with energy

Analysis of subwavelength-patterned plasmonic structures with approximate models

Using approximate analytical models, supported with rigorous comparison, the interaction of optical waves with various classes of plasmonic sub-wavelength-patterned structures, including nanoaperture arrays and layered structures, is studied.

Optical diagnostics of evacuated polyacetal capillary discharge

In this paper our new capillary discharge device built for the soft x-ray laser studies is described and the first experimental results obtained from electrical, optical and UV diagnostics together with code simulations are presented.

Opacity calculations for extreme physical systems: code RACHEL

Abstract Computer simulations of physical systems under extreme conditions (high density, temperature, etc.) require the availability of extensive sets of atomic data. This paper presents basic information on a self-consistent approach to calculations of radiative opacity, one of the key characteristics of such systems. After a short explanation of general concepts of the atomic physics of extreme systems, the structure of the opacity code RACHEL is discussed and some of its applications are presented.
