DESCRIPTION:Speakers: Rasmus Partzsch (University of Bonn)\, Saime Gurbuz 
 (uni-bonn)\n\nAbstract: \n\nBeamline for Schools (BL4S) is an internation
 al outreach and research program that offers high-school students the opp
 ortunity to design and carry out a particle physics experiment at a major 
 accelerator facility. In 2025\, in addition to DESY and CERN\, ELSA too op
 ened its doors to students\, inviting a winning team to carry out their ex
 periment.\nTeam XTReme from Texas\, USA\, was one of the five winning team
 s of the competition and were invited to ELSA to perform their experiment.
  They proposed an experiment to study “Transition Radiation in Multi-Lay
 ered Dielectric–Metallic Targets for Soft X-Ray Generation and Beam Diag
 nostics”. The experiment focused on measuring transition radiation from 
 multilayer dielectric–metallic targets\, also including everyday\, low-c
 ost materials such as cling wrap\, and space blanket foils. The setup comb
 ined an EUDET-type beam telescope for precise particle tracking with a TJ-
 Monopix2 for photon detection. TJ-Monopix2 is a depleted monolithic active
  pixel sensor (DMAPS). The successor chip OBELIX\, is designed for the BEL
 LE II vertex detector upgrade (VTX). Despite the simplicity of the target 
 materials\, transition radiation was successfully observed\, demonstrating
  both the sensitivity of the setup and the feasibility of using inexpensiv
 e materials as TR targets in particle physics experiments.\nIn this talk\,
  we present the preparation of various targets by the students\, the exper
 imental setup at ELSA\, analysis procedures and results. Team XTReme’s m
 easurements confirm that these accessible\, low-cost materials can generat
 e transition radiation\, showing that with a little creativity\, even clin
 g wrap and space blankets can be deployed at particle physics detectors!\n
