Scintillator tile batch test of CEPC AHCAL

Hadron calorimeter (HCAL) is an essential sub-detector of the baseline detector system for Circular Electron Positron Collider (CEPC). We plan to build Analog CALorimeter (AHCAL) prototype based on Particle Flow Algorithm (PFA). The AHCAL CEPC uses steel as absorber and scintillator tiles read out by Silicon Photo-Multipliers (SiPMs) sensitive medium. energy linearity resolution depends light yield uniformity It qualify entire production in order select with uniform within 10\%. An automated batch test platform has been designed 144 channels, 3D servo motor. paper summarizes tests performed more than 15000 tiles. measured yield, corrected set-up response non-uniformity, around 12.9 p.e. . About 91.6\% scintillators (14219 pieces) are qualified 10\% window.
