Description
The ePIC detector is specifically designed to address the entire physics program
at the Electron-Ion Collider (EIC). It consists of several sub-detectors, each tailored
to address specific physics channels. One of the key sub-systems of ePIC is
the dual-radiator Ring Imaging Cherenkov (dRICH) detector, which is a highmomentum
particle-identification system located in the hadronic end-cap. For
this purpose, silica aerogel has been chosen as a solid radiator. The optical and
geometrical characteristics of the aerogel tiles play a critical role in enhancing
the particle identification performance. Intensive R&D efforts are currently underway
to optimize these properties. Ongoing studies are focused on defining and
refining the aerogel tiles to ensure optimal performance. The measurement of the
transmittance of several aerogel tiles with different refractive indices, including
the setup and the measurement method, will be presented.
