Performance test of BESIII TOF electronics by PMT signal

Wu Jinjie Heng Yuekun Sun Zhijia Zhao Yuda Shubin Liu

An easy method is studied to test TOF electronics by PMT signal,which is more near the real situation than signal generator.The test results show that the TOF electronics prototype has met the requirements of the TOF detector.

Design and verification of the HXI collimator onboard the ASO-S mission

arXiv (Cornell University) (2020)

Dengyi Chen Hu Yiming Tao Ma Su Yang Yang Jian-feng

A space-borne hard X-ray collimator, comprising 91 pairs of grids, has been developed for the Hard X-ray Imager (HXI). The HXI is one of the three scientific instruments onboard the first Chinese solar mission: the Advanced Space-based Solar Observatory (ASO-S). The HXI collimator (HXI-C) is a spatial modulation X-ray telescope designed to observe hard X-rays emitted by energetic electrons in solar flares. This paper presents the detailed design of the HXI-C for the qualification model that will be inherited by the flight model. Series tests on the HXI-C qualification model are reported to verify the ability of the HXI-C to survive the launch and to operate normally in on-orbit environments. Furthermore, results of the X-ray beam test for the HXI-C are presented to indirectly identify the working performance of the HXI-C.

Preparation of stripe-shaped domain structure in ferroelectric liquid crystal and the fabrication of spatial light modulator

Acta Physica Sinica (Overseas Edition) (1999)

Ruibo Lu Xu Ke-shu Shuyan Zhang Guiling Xiang Zhongjing Xing

The stripe-shaped domain (SSD) structure was prepared in the initial ferroelectric liquid crystal (FLC) alignment without the application of an external electric field, which was realized by the aligning layer modification through the doping of tin tetra-2, 4-dimethyl phenoxy phthalocyanine (SnPc) into the rubbed polyimide films. Atomic force microscopy was used to investigate the alignment films and the corresponding aligning ability was evaluated through the pre-tilt angle measurement. The memory capability and the contrast ratio of thus aligned SSFLC cells have been enhanced and improved with the appearance of the SSD structure. The electrically controlled 64 × 64 FLC spatial light modulator was fabricated using the improved aligning method, which proves valuable for the practical device fabrication.

Readout Electronics Design of prototype of BGO Calorimeter in Chinese Space Detector for Dark Matter Particle

Acta Astronomica Sinica (2012)

Guo Jian-hua Cai Mingsheng Hu Yi-Ming Jin Chang

The goal of the space detector for dark matter,which is proposed by Purple Mountain Observatory of Chinese Academy of Sciences,is to measure the energy spectra of the gamma-rays and electrons.The whole detector consists of BGO calorimeter and scintillator hodoscope.The detector has a capability of measuring the particle's energy in 10 GeV to 10 TeV,and the main energy of injected particle is deposited in the BGO calorimeter. This paper will introduce the prototype of readout electronics of BGO calorimeter.
