At Louisiana Tech University, we are building Trigger scintillators using an organic scintillator embedded with wavelength shifting (WLS) fibers. Using WLS fiber instead of a light guide leads to the collecting and guiding of light photons toward photo-multiplier tube (PMT) efficiently. We have constructed and tested the initial prototype where we achieved a cosmic muon efficiency above 98%. Currently, the final prototype is under construction. The progress, current status of the final prototype testing, and plans for final detector constructions will be given.
*The project titled "The Parity Violating Electron Scattering Program of Louisiana Tech University" (NSF Grant ID: 2111066) and the project titled "Collaborative Research: Apparatus for Normalization and Systematic Control of the MOLLER Experiment" (NSF Grant ID: 2012518) provided crucial resources and funding that significantly contributed to the research presented in here. We express our sincere gratitude to the NSF for their support, which has been instrumental in the successful execution of this research.
