Gaseous time projection chambers for rare event detection: Results from the T-REX project. I. Double beta decay
I. G. Irastorza, F. Aznar, J. Castel +13
As part of the T-REX project, a number of R&D and prototyping activities have been carried out during the last years to explore the applicability of gaseous Micromegas-read TPCs in…
Gaseous time projection chambers for rare event detection: Results from the T-REX project. II. Dark matter
I. G. Irastorza, F. Aznar, J. Castel +13
As part of the T-REX project, a number of R&D and prototyping activities have been carried out during the last years to explore the applicability of Micromegas-read gaseous TPCs in…
TREX-DM: a low-background Micromegas-based TPC for low-mass WIMP detection
F. J. Iguaz, J. G. Garza, F. Aznar +8
If Dark Matter is made of Weakly Interacting Massive Particles (WIMPs) with masses below 20 GeV, the corresponding nuclear recoils in mainstream WIMP experiments are of energ…
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…
Comissioning of TREX-DM, a low background Micromegas-based Time Projection Chamber for low mass WIMP detection
F. J. Iguaz, J. G. Garza, F. Aznar +8
Dark Matter experiments are recently focusing their detection techniques in low-mass WIMPs, which requires the use of light elements and low energy threshold. In this context, we d…
Exploring 0.1-10eV axions with a new helioscope concept
J. Galán, T. Dafni, E. Ferrer-Ribas +9
We explore the possibility to develop a new axion helioscope type, sensitive to the higher axion mass region favored by axion models. We propose to use a low background large volum…
Lessons from the operation of the "Penning-Fluorescent" TPC and prospects
Diego Gonzalez-Diaz, F. Aznar, J. Castel +15
We have recently reported the development of a new type of high-pressure Xenon time projection chamber operated with an ultra-low diffusion mixture and that simultaneously displays…

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…
