Description
R&D efforts are ongoing to develop a cylindrical Micromegas tracker for the central barrel of the ePIC detector, the first experiment at the future Electron Ion Collider (EIC). The Micromegas detectors will be a part of a multi-technology tracker that needs to fit inside a 1.7 T solenoid, bringing stringent constraints on space, material budget and number of electronic channels. As such, a light resistive Micromegas equipped with a 2D readout is required. The R&D focuses on the optimization of the readout system, which is made of a resistive layer read through capacitive effect by a pattern of readout electrodes. The goal is to minimize the number of readout channels while keeping a good spatial resolution. A beam test with different prototypes has been conducted at the MAMI electron beam, of which preliminary results will be presented.
