Lightweight Soft X-ray Imager (LSXI) with glass-based coded mask
Dali Zhang, Chao Zheng, Lu Wang +23
The coded mask technique has been widely used in X-ray and Gamma-ray imagers, especially in space astronomy. However, the traditional design of coded mask imagers usually has probl…
A Method for Gamma-Ray Energy Spectrum Inversion and Correction
Zhi-Qiang Ding, Xin-Qiao Li, Da-Li Zhang +13
Accurate spectral analysis of high-energy astrophysical sources often relies on comparing observed data to incident spectral models convolved with the instrument response. However,…
Detector performance of the Gamma-ray Transient Monitor onboard DRO-A Satellite
Pei-Yi Feng, Zheng-Hua An, Da-Li Zhang +15
Gamma-ray Transient Monitor (GTM) is an all-sky monitor onboard the Distant Retrograde Orbit-A (DRO-A) satellite with the scientific objective of detecting gamma-ray transients ran…
The Intrinsic Energy Resolution of LaBr(Ce) Crystal for GECAM
Pei-Yi Feng, Xi-Lei Sun, Zheng-Hua An +6
This study aims to provide an accurate estimation of the intrinsic resolution of LaBr(Ce) crystal through a combination of experimental and simulation methods. We re-analyzed t…
The Energy Response of LaBr3(Ce), LaBr3(Ce,Sr) and NaI(Tl) Crystals for GECAM
Pei-Yi Feng, Xi-Lei Sun, Zheng-Hua An +19
The GECAM series of satellites utilize LaBr3(Ce), LaBr3(Ce,Sr), and NaI(Tl) crystals as sensitive materials for gamma-ray detectors (GRDs). To investigate the non-linearity in the…
