We report the performance of a 10 atm Xenon/trimethylamine time projection chamber (TPC) for detection X-rays (30 keV) and γ-rays (0.511–1.275 MeV) in conjunction with accurate tracking associated electrons. When operated at such high pressure ~1%-admixtures, trimethylamine (TMA) endows Xenon an extremely low electron diffusion (1.3±0.13mm-σ (longitudinal), 0.95±0.20mm-σ (transverse) along 1 m drift) besides forming convenient 'Penning-Fluorescent' mixture. The TPC, that houses 1.1 kg gas...
Additive Manufacturing (AM) is gaining importance as an alternative and complementary technology to conventional manufacturing processes. Among AM technologies, the Atomic Diffusion (ADAM) a novel extrusion-based process involving metallic filaments. In this work, widely used 17-4 PH stainless steel filament was selected study effect of different deposition strategies ADAM on mechanical properties. The printed parts had properties comparable those obtained by other more developed...
Abstract Additive Manufacturing (AM) has become the new paradigm of design and production strategies. While structural functional materials are most implemented ones, it is also possible to manufacture parts using precious metals, being copper one interesting. Among AM technologies, novel Atomic Diffusion (ADAM) recently included this material between available ones. ADAM free from thermal energetic issues caused by high reflectivity conductivity which other encounter. Therefore, could be a...
An extensive material screening and selection process is underway in the construction of "Neutrino Experiment with a Xenon TPC" (NEXT), intended to investigate neutrinoless double beta decay using high-pressure xenon gas TPC filled 100 kg Xe enriched 136Xe. Determination radiopurity levels materials based on gamma-ray spectroscopy ultra-low background germanium detectors at Laboratorio Subterráneo de Canfranc (Spain) also Glow Discharge Mass Spectrometry. Materials be used shielding,...
We demonstrate a novel approach for achieving rapid, consistent, and controllable micro-pore fabrication in single-crystalline quartz. These micro-pores are essential applications biology, i.e., studying ion channels general mechano-sensitive (MSC) particular. The process consists of direct material ablation using pulsed UV light from 193 nm excimer laser. pulses ablate quartz chips by burning laser-induced plasma tri-layer structure. Controllable confinement thus pore size is achieved...
