Poster

Physics experiments featuring liquid noble gas time projection chambers are becoming larger in scale.
Consequently, their high voltage (HV) requirements have increased as well, making conventional design HV feedthrough (FT) impracticable.
A new concept for a HV cable FT usable in cryogenic environment is presented.
It features a co-extruded multi-layered coaxial cable fabricated with a...

Poster

Liquid argon is commonly used as a detector medium for neutrino physics and dark matter experiments in part due to its copious scintillation light production in response to its excitation and ionization by charged particle interactions. As argon scintillation appears in the vacuum ultraviolet (VUV) regime and is difficult to detect, wavelength-shifting materials are typically used to convert...

612. WITHDRAWN - Spectroscopic-based particle discrimination in Ar gas

Sensors: Noble liquid detectors

Poster

We performed a time-resolved spectroscopic study of the VUV/UV scintillation in argon gas as a function of pressure and electric field, with a wavelength sensitive detector operated with different radioactive sources. Distinctive features of the argon light are evidenced, which are in contrast with the general assumption that the scintillation is mainly monochromatic at 128 nm.
