Abstract
The objective of this program is to pursue opportunities to reduce the material budget and the cost of the DIRC counter for the EIC, without loss of performance, by investigating fundamental DIRC performance limits and new optical configurations. The barrel high-performance DIRC (hpDIRC) has been adopted for the ePIC detector and is an attractive solution for Detector-2. In this program, we study the DIRC performance with an innovative optical configuration consisting of narrow, thin radiator bars coupled to wide plates, focusing lenses, and small expansion volume prisms. The outcomes of these studies would be applicable to both ePIC and, in particular, to Detector-2. This novel geometry goes well beyond the design established for ePIC and may enable opportunities for the application of SiPM and the DIRC readout. This innovative optics is expected to lower the impact of DIRC material on the electromagetic calorimeters (improving the physics reach of the EIC detector), whereas the use of hybrid optics and SiPM readout consitutes an advancement of DIRC technology.
