Characterization of Charge Spreading and Gain of Encapsulated Resistive Micromegas Detectors for the Upgrade of the T2K Near Detector Time Projection Chambers
D. Attie, O. Ballester, M. Batkiewicz-Kwasnia +92
An upgrade of the near detector of the T2K long baseline neutrino oscillation experiment is currently being conducted. This upgrade will include two new Time Projection Chambers, e…
Analysis of test beam data taken with a prototype of TPC with resistive Micromegas for the T2K Near Detector upgrade
D. Attié, O. Ballester, M. Batkiewicz-Kwasniak +81
In this paper we describe the performance of a prototype of the High Angle Time Projection Chambers (HA-TPCs) that are being produced for the Near Detector (ND280) upgrade of the T…
An instrumented baffle for the Advanced Virgo Input Mode Cleaner End Mirror
M. Andres-Carcasona, O. Ballester, O. Blanch +21
A novel instrumented baffle surrounding the suspended end mirror in the input mode cleaner cavity of the Virgo interferometer was installed in spring 2021. Since then, the device h…
Development and Characterization of a Multi-APD Xenon Electroluminescence TPC
T. Lux, A. Garcia Soto, O. Ballester +11
The performance of an electroluminescence (EL) Time Projection Chamber (TPC) with a multi avalanche photodiode (APD) readout was studied in pure xenon at 3.8 bar. Intercalibration…
Characterization of the Hamamatsu S8664 Avalanche Photodiode for X-Ray and VUV-light detection
T. Lux, E. D. C. Freitas, F. D. Amaro +6
We present the first operation of the Avalanche Photodiode (APD) from Hamamatsu to xenon scintillation light and to direct X-rays of 22.1 keV and 5.9 keV. A large non-linear respon…
A Multi-APD readout for EL detectors
T. Lux, O. Ballester, J. Illa +4
Detectors with an electroluminesence readout show an excellence performance in respect of energy resolution making them interesting for various applications as X-ray detection, dou…
