Description

The Electron Ion Collider (EIC) at Brookhaven National Laboratory (BNL) and ePIC, its first experiment, aim to advance the nuclear physics frontier starting from 2035.
Studying the collisions between the EIC’s polarized beams will allow to probe the internal structure nucleons and nuclei with unprecedented precision, to shed light on the origin of spin in the nucleons, and to investigate the phenomenon of gluon saturation at high energies.
The central detector has a compact, hermetic design and provides a unique platform to develop and test new advancements in detector technologies 10 years before the scheduled start of the Future Circular Collider’s physics program.
The tracking system of ePIC consists of silicon and micropattern gaseous detectors (MPGDs). Two world-first technologies will be implemented here, one of them being the hybrid GEM/μ-RWELL detectors of the Barrel Outer Tracker (BOT) and Endcap Tracker (ECT).
This contribution will present the preliminary design of the ECT G-RWELL disks, discuss their physics and integration constraints, and showcase the solutions adopted to meet them. A report on the status of production and testing of the first engineering test articles (ETA) of the disks’ base modules will also be provided, together with a description of tooling and procedures developed for their realization.
