Description
Uniform detector response is essential for reliable crystal evaluation
and selection in scintillation-based detection systems. In this study,
the response of a multi-channel SiPM array was equalized using a
reference GAGG crystal, with a LYSO source generating a stable energy
peak signal for calibration. By aligning the energy peak response across
all channels, a consistent detector response baseline was established.
Based on this calibrated condition, a newly fabricated batch of GAGG
crystal arrays were rapidly evaluated. The performance of each crystal
array was characterized in terms of response uniformity, count rate, and
peak location distribution. These statistical indicators were used to
identify non-uniform or outlier crystals.
Using this systematic screening method, crystals with stable and
consistent characteristics were selected for integration into the
FORMOSAT-8D GPM instrument, enabling efficient large-scale crystal
qualification.
