    Abstract: With the development of the circular collider, it is necessary to make accurate physics experimental measurements of particle properties at higher luminosity [Formula: see text] pole. Micro-pattern gaseous detectors (MPGDs), which contain gaseous electron multiplier (GEM) and micro-mesh gaseous structures (Micromegas), have excellent potential for development as the readout devices of the time projection chamber (TPC) tracker detector. To meet the updated physics requirements of the high luminosity [Formula: see text] from the preliminary concept design report (preCDR) to concept design report (CDR) at the circular electron–positron collider (CEPC). In this paper, the space charge distortion of the TPC detector is simulated with the CEPC beam structure. Using the multi-physics simulation software package, the distribution of ion estimated by Geant4 is used as the input for the differential equation, and the relationship between the ion density distribution and electric field in the detector chamber is simulated. These simulation results show that the maximum deviation for Higgs [Formula: see text] meets the performance requirements in CEPC TPC detector at the high luminosity [Formula: see text] pole, while it is still a considerable challenge for [Formula: see text] pole, with the maximum deviation [Formula: see text] . According to the previous developments, the cascaded structure of GEM and Micromegas detector has been measured. The new considerations of the detector’s requirements were given, the gain needs to be reached to about 2000 with IBF[Formula: see text]Gain under 0.1, and IBF means the ions back flow ratio of the detector. The pixel TPC is a potential option to replace the traditional MPGDs with the low gain, low occupancy, and outstanding pattern recognition. Finally, some update parameters and experiments results were compared.

    Abstract: The Circular Electron–Positron Collider (CEPC) has been proposed as a Higgs and high luminosity [Formula: see text] factory for the last few years in China. To achieve the high precision physical goals at CEPC, the high resolution ([Formula: see text] ) tracker for the particle track reconstruction and particle identification are demanded. Time Projection Chamber (TPC) is one of the main concept proposal of the central tracker detector in very large 3D volume, it has an excellent performance on the moment measurement, [Formula: see text] measurement and the spatial resolution. The simulation results were given when the TPC detector will operate at the high luminosity [Formula: see text] pole at the future [Formula: see text] circular collider. The pixelated readout TPC is a potential option to replace the traditional pad readout with the low gain, low occupancy, and outstanding pattern recognition. In the last several years, a TPC module, the readout electronics and prototype for the specific requirements have been developed at the Institute of High Energy Physics (IHEP). TPC module will could suppress the ions in chamber continuously running in the different gains (2000–5000) under T2K mixture gases. A TPC prototype with [Formula: see text] active area G detector module integrated the narrow 266[Formula: see text]nm UV laser tracks along the drift length of 500[Formula: see text] mm, and the low power consumption ([Formula: see text]) Application-Specific Integrated Circuits (ASIC) chip including analog to digital converter (ADC) function has been developed too. The update results of the spatial resolution has been obtained after some experimental studies have been done by the TPC prototype.

    Abstract: The discovery of a SM Higgs boson at the LHC brought about great opportunity to investigate the feasibility of a Circular Electron Positron Collider (CEPC) operating at center-of-mass energy of 240 GeV, as a Higgs factory, with designed luminosity of about [Formula: see text]. The CEPC provides a much cleaner collision environment than the LHC, it is ideally suited for studying the properties of Higgs boson with greater precision. Another advantage of the CEPC over the LHC is that the Higgs boson can be detected through the recoil mass method by only reconstructing [Formula: see text] boson decay without examining the Higgs decays. In Concept Design Report (CDR), the circumference of CEPC is 100 km, with two interaction points available for exploring different detector design scenarios and technologies. The baseline design of CEPC detector is an ILD-like concept, with a superconducting solenoid of 3.0 Tesla surrounding the inner silicon detector, TPC tracker detector and the calorimetry system. Time Projection Chambers (TPCs) have been extensively studied and used in many fields, especially in particle physics experiments, including STAR and ALICE. The TPC detector will operate in continuous mode on the circular machine. To fulfill the physics goals of the future circular collider and meet Higgs/[Formula: see text] run, a TPC with excellent performance is required. We have proposed and investigated the ions controlling performance of a novel configuration detector module. The aim of this study is to suppress ion backflow (IBF) continually. In this paper, some update results of the feasibility and limitation on TPC detector technology R & D will be given using the hybrid gaseous detector module.
