“…The ionization current in 5 cm argon ∼ 1 nA, and the error between it and the minimum sensitivity is 5%, which has met our experimental requirements. In addition, the sensitive gas thickness of the Side-On TRD prototype we developed previously was 5 cm [5], to match it, the sensitive gas thickness of the detector here is chosen to be 5 cm.…”

“…In previous works, we have proposed and developed a new prototype of TRD based on THGEM, called Side-On TRD, which would be applied for TeV energy scale calibration in-orbit of calorimeter in HERD [4]. The Side-On TRD has been tested at CERN SPS in December 2018 and has achieved good results [5]. A TRD is composed of a radiator and a photon detector.…”

“…The HERD payload consists of a calorimeter (CALO) [5], a fiber tracker (FIT) [6], a plastic scintillator detector (PSD) [7], a silicon charge detector (SCD) and a transition radiation detector (TRD) [8]. The CALO is the core detector of the HERD, and it is a homogeneous, 3D segmented calorimeter made up of about 7500 LYSO cubes with 3 cm side lengths, corresponding to roughly 55 radiation lengths(X0) and 3 nuclear interaction lengths for centrally incident particles in any directions, respectively.…”

A novel 3-D calorimeter, composed of about 7500 LYSO cubes, is the key and crucial detector of the High Energy cosmic-Radiation Detection (HERD) facility to be installed onboard the China Space Station. Energy deposition from cosmic ray in each LYSO cube is translated by multiple wavelength shifting (WLS) fibers for multi-range data acquisition and real-time triggering. In this study, various methods of surface finish and encapsulation of the LYSO cube were investigated to optimize the amplitude from the WLS fiber end with the aim of improving the signal-to-noise ratio of Intensified scientific CMOS (IsCMOS) collection. The LYSO cube with five rough surfaces and a specular reflector achieves the maximum amplitude at the low-range fiber end, which is increased by roughly 44% compared to the polished cube with PTFE wrapping. The non-uniformity of amplitude at different positions on the LYSO cube surface was measured by X-ray and the positional correlation factor was derived for the entire cube. A simulation based on HERD CALO was conducted, which revealed that both the LYSO cube with five rough surfaces and the cube with rough bottom face exhibit superior energy resolution for electrons compared to the other two configurations.

“…A side-on TRD prototype was developed and its performance was studied by using electron beams. We tested the properties of different working gases and the performance of THGEM with various parameters by using the 55 𝐹𝑒 source [9]. The regular radiator parameters were optimized using a fast calculating program [10] and were tested using electron beams [11].…”

The High Energy cosmic-Radiation Detection facility (HERD) is a calorimetry-based cosmic-ray detection mission on board China space station. A side-on transition radiation detector (TRD) focuses on the TeV energy range calibration of the HERD calorimeter with an error of less than 10% by measuring the Lorentz factor γ of high-energy cosmic-ray protons. A side-on TRD prototype was developed for the performance study and tested by Deutsches Elektronen-Synchrotron electron beams. In this paper, the Monte Carlo simulation based on GEANT4 was compared with the experiment results. All simulations were in good agreement with the test beam results.
