“…The BESIII (Beijing Spectrometer III) Experiment operates since 2009 at the Beijing e+e-collider (BEPCII), hosted by the Institute of High Energy Physics (IHEP) [1]. The inner drift chamber is suffering early aging due to the increased machine luminosity, which has reached 1.0 x 10 33 cm −2 s −1 .…”

TIGER (Turin Integrated Gem Electronics for Readout) is a mixed-mode ASIC for the readout of signals from CGEM (Cylindrical Gas Electron Multiplier) detector in the upgraded inner tracker of the BESIII experiment, carried out at BEPCII in Beijing. The ASIC includes 64 channels, each of which features a dual-branch architecture optimized for timing and energy measurement. The input signal time-of-arrival and charge measurement is provided by low-power TDCs, based on analogue interpolation techniques, and Wilkinson ADCs, with a fully-digital output. The silicon results of TIGER first prototype are presented showing its full functionality.

“…We define t ia , T i , and Tr i to easily and effectively emphasized our analysis process bellow. t ia is used to describe the arrival time which i(i=1, 2,3,4) represents the different module and a(a=1,2)represents the two ends of strip pad. T i = (t i1 + t i2 )/2 can be regarded as average hit-time of the strip.…”

“…The Beijing Spectrometer III(BESIII ) [1,2] is a high precision general-purpose detector designed for high luminosity e + ecollisions in the τ-charm energy region at the Beijing Electron and Positron Collider II(BEPCII) [3][4][5]. In high energy collision experiments particle identification (PID) play a crucial role, especially for hadrons analysis in τ-charm physics.…”

In order to improve the particle identification capability of endcap time-of-flight (ETOF) at Beijing Spectrometer III, it is proposed to upgrade current ETOF detector with multi-gap resistive plate chamber (MRPC) technology aiming at extending ETOF overall time resolution to be 80-100 ps for π 's. The new ETOF system including MRPC detectors, front end electronics, CLOCK module, fast control boards and time-to-digital conversion modules, was built up and underwent 3-month cosmic ray test. The main purposes of the cosmic ray test are examining the construction quality of the system, testing the joint operation of all instruments and guaranteeing the system performance. The results show that MRPC time resolution is better than 80 ps, average efficiency is about 98.5 % and the noise rate of strip is 0.2 Hz/cm 2 at the threshold range for normal operation. These results indicate that the entire ETOF system would work well and satisfy the requirements of upgrade.

“…The Beijing electron-positron collider (BEPC) and its detectors the Beijing Spectrometer (BES) were successfully updated to the BEPCII and BESIII in 2009 [1], the whole detector's performance achieved the design goal. The Time of Flight detector (TOF) used to measure the flight time of charged particles for particle identification (PID) is one of the most important sub-detectors of BESIII.…”

The designed aim of the multi-gap resistive plate chamber module (MRPC) for the BESIII endcap TOF upgrade project is less than 50 ps, so a Time-zero (T0) system is required to achieve the timing resolution at 30 ps level. After study the scintillator, the PMT, the DAQ subsystem, the assemblage form and the distributing position, the timing resolution of this type of T0 detector composed of scintillator BC420 coupling with PMT H6533 could achieve 30 ps level. Further more, the T0 could also perform the particle identification (proton and pion) just as the beam TOF and EMC detectors during the beam test process for the compelling result. For this type of T0 system, the MRPC beam test was finished and achieved a compelling result.
