IIn contemporary high-energy physics experiments, ​non-destructive beam monitoring detectors are critical devices used for real-time, non-invasive measurements of particle beam parameters (e.g., intensity, position, profile, energy distribution), ensuring experimental precision and stability. The ​Micro-Mesh Gaseous Detector (Micromegas), with its advantages in ​radiation resistance, high temporal and spatial resolution, low material density, and cost-effectiveness, demonstrates significant potential in the field of non-destructive beam monitoring.

The double-layer mesh Micromegas detector, developed based on the traditional single-layer mesh Micromegas detector, is a structurally more complex high-performance gas detector designed for specific applications. It inherits the high precision and high counting rate advantages of the traditional single-layer mesh Micromegas detector while achieving two-stage electron multiplication through its double-layer mesh structure. This design enhances detector stability and increases the gain limit. As a readout detector for Time Projection Chambers (TPC), the double-layer mesh structure significantly suppresses ion feedback, thereby improving the TPC system's counting rate.

The dual-end readout Time Projection Chamber (TPC) system based on microstructure gas detectors significantly enhances the three-dimensional trajectory reconstruction, energy resolution, and particle identification capabilities of charged particles by integrating novel detector technologies, multi-channel signal processing algorithms, and high-precision track reconstruction methods. This technology holds significant application value in fields such as nuclear physics, particle physics, and astrophysics.

The development of a high-pressure TPC system based on Micromegas readout, featuring high granularity, high energy resolution, low radioactive background, and long-term stable operation, holds excellent application prospects in high-energy physics experiments, particularly in exploring rare event experiments. The company’s low-background high-pressure Micromegas detector solution, developed for the PandaX-III neutrinoless double beta decay experiment, has undergone rigorous validation in all aspects of performance.
