Abstract
R&D efforts are ongoing to develop the Cylindrical Micromegas Barrel Layer (CyMBaL) for the central region of the ePIC detector, the first experiment at the future Electron Ion Collider (EIC). The Micromegas detectors will be part of a multi-technology tracker located inside a
1.7 T solenoid, bringing stringent limits on space. Constraints on momentum reconstruction performances also impose a low-material budget in order to not degrade the measurements of detectors placed behind. As such, a light resistive Micromegas equipped with a 2D readout is needed. The R&D goal is to optimise the readout system to limit the number of channels while keeping a spatial resolution of about 150 𝜇m.
The first prototypes for CyMBaL were designed to compare different readout patterns. This work presents the results of the prototypes tested at the MAMI facility in Mainz on a 880 MeV electron beam.
