Characterization of a medium size Xe/TMA TPC instrumented with microbulk Micromegas, using low-energy -rays
The NEXT collaboration, V. Alvarez, F. I. G. M. Borges +87
NEXT-MM is a general-purpose high pressure (10 bar, l active volume) Xenon-based TPC, read out in charge mode with an 8 cm 8 cm-segmented 700 cm plane (1152 ch…
Description and commissioning of NEXT-MM prototype: first results from operation in a Xenon-Trimethylamine gas mixture
NEXT Collaboration, V. Ãlvarez, F. Aznar +82
A technical description of NEXT-MM and its commissioning and first performance is reported. Having an active volume of ~35 cm drift 28 cm diameter, it constitutes the larg…
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…
TREX-DM: a low background Micromegas-based TPC for low mass WIMP detection
F. J. Iguaz, J. G. Garza, F. Aznar +11
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 p…
The potential of discrimination methods in a high pressure xenon TPC for the search of the neutrinoless double-beta decay of Xe-136
F. J. Iguaz, F. Aznar, J. F. Castel +8
In the search for the neutrinoless double beta decay of Xe, a high pressure xenon time projection chamber (HPXe-TPC) has two advantages over liquid xenon TPCs: a better ene…
X-ray detection with Micromegas with background levels below 10 keVcms
S. Aune, F. Aznar, D. Calvet +26
Micromegas detectors are an optimum technological choice for the detection of low energy x-rays. The low background techniques applied to these detectors yielded remarkable backgro…
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…
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…
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…

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…
Accurate gamma and MeV-electron track reconstruction with an ultra-low diffusion Xenon/TMA TPC at 10 atmospheres
