This seminar will consist of three student speakers who have completed HEP research projects over the summer.

Speaker: Jonas Dej

Title: proANUBIS Data Analysis

Abstract: ANUBIS is a proposed experiment to discover Long-Lived Particles by placing Resistive Plate Chambers on the ceiling of the ATLAS cavern. Given its high sensitivity and low cost, it is one of the most promising projects of its kind. In my talk, I will present the progress in its data analysis techniques, including particle track reconstruction, alignment with the ATLAS detector, and signal corrections.

Speaker: Jesse (Yingchang) Zhang

Title: Development of Efficiency Testing System and the Study of Eco-friendly Gas in RPC

Abstract: The ANUBIS detector aims to search for dark matter through the signatures of long-lived particles, utilizing a series of tracking detectors, including Resistive Plate Chambers (RPCs). This project focuses on developing and enhancing the system for evaluating RPC efficiency and testing performance of potential eco-friendly gas candidates.

The experiment utilized two methods—scintillator-triggered and RPC self-triggered modes—to measure the efficiency of RPCs with various gas mixtures, including the standard CERN mixture (as a reference), isobutane, krypton, and argon mixed with CO₂. Results indicated that while argon alone was an ineffective RPC gas, adding approximately 3% argon to an 80% isobutane + 20% CO₂ mixture significantly improved efficiency in self-triggered mode. Additionally, the study investigated the impact of high-voltage training on enhancing RPC performance.

Speaker: Shikang Ni

Title: Experiment to Measure Muon Lifetime using 5×5 Array of Scintillator Bars

Abstract: Cosmic rays offer a convenient and free source of energetic particles for high energy physics experiments. Muons, being the most abundant charged particles arriving at sea levels, are a good target to perform measurements on. By capturing muons in a scintillator bar and measuring its decay time, we can work out its average lifetime. To build an experiment with multiple interacting components, it is essential to understand the experimental setup and check that individual components are working properly. In my talk, I will go over a brief theoretical understanding of the experiment and the evolution of the experimental setup.
