Micromegas Detector for the Cast Experiment
نویسندگان
چکیده
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 the construction of the detector. For the second phase of the experiment (2005-2007), the detector will be upgraded by adding a shielding and including focusing optics. These improvements should allow for a background rejection better than two orders of magnitude.

The 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.
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...
متن کاملMicromegas performance test for ( n , α ) measurements at n _ TOF : 33 S ( n , α ) cross section
Presently, a neutron detector based on the Micromegas concept is running at n_TOF facility at CERN for monitoring purposes. The main goal of the letter is a first (n,α) cross section measurement by using the Micromegas detector. The transmission of the sample and detector allow performing the experiment in parasite mode. In the future a series of (n,α) measurements would be performed at n_TOF o...

The MICROMEGAS detector concept, generally optimized for use in accelerator experiments, displays a peculiar combination of features that can be advantageous in several astroparticle and neutrino physics applications. Their subkeV ionization energy threshold, excellent energy and space resolution, and a simplicity of design that allows the use of radioclean materials in their construction are s...
متن کاملEnergy 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 ...
