Description
The High Energy cosmic-Radiation Detector (HERD) is a proposed space as-
tronomy payload for the China Space Station. Its main goal is to detect charged
cosmic-rays with energies up to a few PeV and gamma-rays with energies above
100 MeV. The Plastic Scintillator Detector (PSD) is a crucial component of
HERD, and it is designed to identify photons and accurately measure the charge
of incoming cosmic rays, ranging from protons to iron. The PSD must have high
detection efficiency, a broad dynamic range, and optimal energy/charge resolu-
tion to fulfill its requirements.
The performance of the PSD detector was tested during 2022 and 2023
through beam test sessions at CERN and the CNAO (Centro Nazionale di
Adroterapia Oncologica) in Italy. Several PSD prototypes were tested to evalu-
ate their performance with different particles at different momenta. The results
of these tests will be presented and compared in terms of energy resolution and
ion identification capability, which includes identification of ions with atomic
numbers up to Z ∼26.
