Zito arXiv: 1907.07060 · 2020-02-19 ## TL;DR This paper evaluates a resistive MicroMegas module designed for the T2K ND280 upgrade, demonstrating it meets the necessary spatial and energy resolution requirements through beam tests at CERN. ## Contribution It presents the design, construction, and performance characterization of a resistive MicroMegas module for neutrino detector upgrades, showing it fulfills the specified resolution criteria. ## Key findings - Spatial resolution of 300 μm achieved - Energy resolution of 9% observed - Performance meets upgrade requirements ## Abstract An upgrade of the Near Detector of the T2K long baseline neutrino oscillation experiment, ND280, has been proposed. This upgrade will include two new Time Projection Chambers, each equipped with 16 resistive MicroMegas modules for gas amplification. A first prototype of resistive MicroMegas has been designed, built, installed in the HARP field cage, and exposed to a beam of charged particles at CERN. The data have been used to characterize the performances of the resistive MicroMegas module. A spatial resolution of 300 $\mu m$ and a deposited energy resolution of 9% were observed for horizontal electrons crossing the TPCs at 30 cm from the anode. Such performances fully satisfy the requirements for the upgrade of the ND280 TPC. ## Full text _Full body text omitted from this summary view._ Fetch the complete paper as Markdown: https://tomesphere.com/paper/1907.07060/full.md ## Figures 61 figures with captions in the complete paper: https://tomesphere.com/paper/1907.07060/full.md ## References 22 references — full list in the complete paper: https://tomesphere.com/paper/1907.07060/full.md --- Source: https://tomesphere.com/paper/1907.07060
