Energy resolution of alpha particles in a microbulk Micromegas detector at high pressure Argon and Xenon mixtures
The latest Micromesh Gas Amplification Structures (Micromegas) are achieving outstanding energy resolution for low energy photons, with values as low as 11% FWHM for the 5.9 keV line of Fe in argon/isobutane mixtures at atmospheric pressure. At higher energies (MeV scale), these measurements are more complicated due to the difficulty in confining the events in the chamber, although there is no ...
متن کاملThe Micromegas detector of the CAST experiment
A low background Micromegas detector has been operating in the CAST experiment at CERN for the search of solar axions during the first phase of the experiment (2002-2004). The detector, made out of low radioactivity materials, operated efficiently and achieved a very low level of background rejection (5 × 10 −5 counts keV −1 cm −2 s −1) without shielding.

A low background Micromegas detector has been operating on the CAST experiment at CERN for the search of solar axions during the first phase of the experiment (2002-2004). The detector operated efficiently and achieved a very low level of background rejection (5 × 10 −5 counts keV −1 cm −2 s −1) thanks to its good spatial and energy resolution as well as the low radioactivity materials used in ...
متن کاملModeling and Simulation of a Molecular Single-Electron Transistor
In this paper, to understand the concept of coupling, molecule density of states that coupled to the metal electrodes will be explained then, based on this concept, a weak and strong coupling for the molecules attached to the metal electrodes will be described. Capacitance model is used to explore the connection of addition energy with the Electron affinity and the ionization energy of the mole...
متن کاملPerformance of the Micromegas detector in the CAST experiment
The gaseous Micromegas detector designed for the CERN Axion search experiment CAST, operated smoothly during Phase-I, which included the 2003 and 2004 running periods. It exhibited linear response in the energy range of interest (1-10keV), good spatial sensitivity and energy resolution (15-19% FWHM at 5.9 keV) as well as remarkable stability. The detector’s upgrade for the 2004 run, supported b...
