Ultra low energy results and their impact to dark matter and low energy neutrino physics
E. Bougamont, P. Colas, J. Derre +9
We present ultra low energy results taken with the novel Spherical Proportional Counter. The energy threshold has been pushed down to about 25 eV and single electrons are clearly c…
Energy resolution of alpha particles in a microbulk Micromegas detector at high pressure Argon and Xenon mixtures
T. Dafni, E. Ferrer-Ribas, I. Giomataris +5
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 li…
A novel large-volume Spherical Detector with Proportional Amplification read-out
I. Giomataris, I. Irastorza, I. Savvidis +11
A new type of radiation detector based on a spherical geometry is presented. The detector consists of a large spherical gas volume with a central electrode forming a radial electri…
Progress on a spherical TPC for low energy neutrino detection
S Aune, P Colas, H Deschamps +18
The new concept of the spherical TPC aims at relatively large target masses with low threshold and background, keeping an extremely simple and robust operation. Such a device would…
Micromegas in a Bulk
I. Giomataris, R. De Oliveira, S. Andriamonje +6
In this paper we present a novel way to manufacture the bulk Micromegas detector. A simple process based on the PCB (Printed Circuit Board) technology is employed to produce the en…
