Abstract

The JUNO (Jiangmen Underground Neutrino Observatory) experiment is a multi-purpose neutrino experiment designed to determine the neutrino mass hierarchy and precisely measure oscillation parameters. It will be composed of a 20k ton liquid scintillator (LS) central detector equipped with about 18000 20-inch photon-multipliers (PMTs) and 25000 3-inch PMTs, a water Cherenkov detector with about 2000 20-inch PMTs, and a top tracker. Monte-Carlo simulation is a fundamental tool for optimizing the detector design, tuning reconstruction algorithms, and performing physics study. The status of JUNO simulation software will be presented, including generator interface, detector geometry, physics processes, MC truth, pull-mode electronic simulation.

Summary

JUNO introduction

The Jiangmen Underground Neutrino Observatory (JUNO) [1] is a multi-purpose neutrino observatory under construction in the southeast of China. It will be located at a distance of 53km from two major nuclear power plants, Yangjiang and Taishan. The central detector is a liquid scintillator (LS) detector of 20 kton mass with a designed energy resolution of 3% at 1MeV, equipped with about 18000 20-inch Photomultiplier Tubes (PMTs) and 25000 3-inch PMTs. The central detector is submerged in a water pool to be shielded from natural radioactivity from the surrounding rock and air. The JUNO simulation software is used to study the detector response and optimize the detector design It consists of three components: kinematic generator, detector simulation and electronics simulation
