Advanced Ray Tracing Simulation for Radiation Analysis in Neutrino Detection

This work outlines the completion and ongoing tasks for the ray tracing component in neutrino and radiation studies, incorporating SHADE into the existing codebase. Key inputs include shower position and solution type, with outputs measuring radiation angles, path length, propagated time, and attenuation factors. The project leverages directed and reflected radiation for enhanced detection accuracy. An accompanying flowchart illustrates voltage changes across time and frequency domains, culminating in signal analysis via FFT to detect neutrino events with a focus on precise hit calculations.

  1. Ray Tracing 5 Hsin-Yi Tu Guided by Pisin Chen, Melin Huang Shi-Hao Wang

  2. Finished • On-going • Next Working Items • Insert SADE in Shang-Yu‘s code completely. (Thanks Shi-Hao a lot !) • Input : shower position. • solution type. • (1: directed radiation; 2: reflected radiation; 3: both of them) • Output : radiation’s angle. • path length. • propagated time. • attenuation factor.

  3. Ray Trace antenna Reflected radiation (xant ,yant ,zant) → (0, zant) Directed radiation θ0 θdir θref υ Shower position (xsh ,ysh ,zsh) → ( r , zsh)

  4. Flow chart for voltage • Modification Vinitial (bipolarwave)(t-domain) Vinitial (f-domain) Vreceived (f-domain) Vreceived (t-domain) + noise Find V max (signalvalue) and observed time Arrange in order (voltage value) FFT Propagation (SADE) FFT noise = Gaussian function (random number)

  5. n_detection – dis_Event_Cuben_hit – dis_Event_Cube 10 events neutrino θ n_detection : θ < 90 o n_hit : get hit in SADE dis_Event_Cube : distance from the center (0,0,0) to shower position

  6. rs0 = ＊ : n_detection ● : n_hit ddr = Zantenna – Zshower
