Performances of a resistive MicroMegas module for the Time Projection Chambers of the T2K Near Detector upgrade

Understand

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.
