Günümüzde kuvars çekirdekli fiberler hem iletişim hem de yüksek radyasyon dirençleri sayesinde bilimsel çalışmalarda yoğunlukla kullanılmaktadır. Fiberin kuvars çekirdeği Çerenkov fotonu üretebilme ve üretilen bu fotonları yada dışarıdan fiber içerisine giren fotonları iletebilme kabiliyeti sayesinde yüksek enerji fiziği ve nükleer fizik alanlarında dedektör tasarımlarında sıklıkla kullanılmaktadır. Bu çalışmada, kuvars çekirdekli fiberlerin foton üretimi ve iletimi üzerine Geant4 simülasyon uygulaması kullanılarak detaylı bir simülasyon geliştirilmiştir. Geant4 simülasyon ortamında Molex firmasının son dönemlerde geliştirmiş olduğu FBP(FBP600660710) geniş bant kuvars çekirdekli fiberleri kullanılmıştır. Bir kuvars çekirdekli fiber üzerine belirli çarpma açılarında ve fiber üzerindeki belirli çarpma noktalarına yüklü parçacıklar gönderilerek, fiberin Çerenkov fotonları üretimi ve iletimi incelenmiştir. Elde edilen verilere dayanarak, foton kayıplarını azaltmak amacıyla fiberin açık ucuna yansıtıcı entegre edilerek testler tekrar gerçekleştirilmiştir. Fiber uzunluğunun fiberin foton taşıma kapasitesi üzerine etkileri de incelenmiştir.

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.
