2026-07-16 Simulation and Offline Test of the Time-of-Flight Detector for the Isochronous Mass Measurement Terminal at HIAF-SRing doi:10.57760/sciencedb.j00186.01176 en The dataset contains relevant data generated from the design and development of TOF detectors at the Institute of Modern Physics in Lanzhou, China from 2024 to 2026. The simulation part was obtained using SIMION optical simulation software, and the offline testing part was obtained using the offline testing platform on the first floor of Building 5 at the Institute of Modern Physics. The "txt" format file is a widely used text file in the field of scientific research, which contains all the images related to the data involved in the article. The following are specific content introductions for each file: （1）“F5-Offline-Backward_Forward_Coin-Signals-604Zi.txt”， Corresponding to Figure 5 of the article, it shows a series of forward, backward, and coincidence signals measured during offline testing; （2）“F6-Offloine-VersionG-MCP1-2200V-MCP2-2200V-Equring-5.txt”， Corresponding to Figure 6 of the article, it is the statistical distribution of the time difference between the forward and backward directions measured in offline testing when the voltage of the equalizing ring is 6600V. The time resolution and error of the detector can be obtained, and the error comes from Gaussian fitting error; （3）“F7-Offline-604Zi-VersionG-180Vpermm-Time-Coin_MCP-5.txt”， Corresponding to Figure 7 of the article, it is the statistical distribution of the time difference between the measured coincidence signal and the positive signal in offline testing, and the error comes from the fitting error; （4）“F8-TimeResolutionVSEqualizing_E.txt”， Corresponding to Figure 8 of the article, it shows the relationship between the time resolution of the detector and the voltage of the equalizing ring under different electric field strengths in offline testing; The relationship between detector time resolution and electric field strength in offline testing and simulation; （5）“F9-TimeResolutionVSEqualizing_E.txt”， Corresponding to Figure 9 of the article, it shows the relationship between detector time resolution and electric field strength in offline testing and simulation; （6）“F10-Offline-604Zi-E-Efficiency.txt”， Corresponding to Figure 10 of the article, it shows the trend of changes in the forward, backward, and overall detection efficiency of the detector under different electric field strengths in offline testing.
