Kuvars Çekirdekli Fiberlerde Cherenkov Fotonlarının Üretimi ve İletimi Üzerine Geant4 Simülasyon Çalışması

In today's world, quartz-core fibers are extensively used in scientific studies due to their high radiation resistance. Thanks to the quartz core's ability to generate Cherenkov photons and propagate these photons, as well as those entering the fiber from outside, it is frequently studied in the context of high-energy and nuclear physics for detector designs. In this paper, a detailed simulation was developed using the Geant4 simulation application, focusing on the photon production and propagation capabilities of quartz-core fibers. Molex's recently developed FBP (FBP600660710) broadband quartz-core fibers were integrated in the simulation environment. The production and propagation of Cherenkov photons were tested by having a charged particle pass through a specific impact point and angle on a quartz-core fiber. Based on the obtained data, reflectors were integrated onto the open end surface of the fiber to reduce photon losses, and tests were conducted again. The effects of fiber length on the photon-carrying capacity of the fiber were also tested.
