A Micromegas-based low-background x-ray detector coupled to a slumped-glass telescope for axion research
F. Aznar, J. Castel, F. E. Christensen +18
We report on the design, construction and operation of a low background x-ray detection line composed of a shielded Micromegas (micromesh gaseous structure) detector of the microbu…
Low Background Micromegas in CAST
J. G. Garza, S. Aune, D. Calvet +22
Solar axions could be converted into x-rays inside the strong magnetic field of an axion helioscope, triggering the detection of this elusive particle. Low background x-ray detecto…
Search for chameleons with CAST
V. Anastassopoulos, M. Arik, S. Aune +61
In this work we present a search for (solar) chameleons with the CERN Axion Solar Telescope (CAST). This novel experimental technique, in the field of dark energy research, exploit…
New solar axion search in CAST with He filling
M. Arik, S. Aune, K. Barth +60
The CERN Axion Solar Telescope (CAST) searches for conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward the Sun. Two parallel m…
Lowering the background level and the energy threshold of Micromegas x-ray detectors for axion searches
F. J. Iguaz, S. Aune, F. Aznar +14
Axion helioscopes search for solar axions by their conversion in x-rays in the presence of high magnetic fields. The use of low background x-ray detectors is an essential component…
