Monte Carlo simulations of microchannel plate detectors. I. Steady-state voltage bias results

ISAC time-of-flight system with laser-based calibration

“…For 10-12 mm pore diameter the time resolution is expected to be in the range of 60-80 ps from Monte-Carlo simulations [8]. The overall timing jitter of the selected electronics is dominated by the walk time of the constant fraction discriminator (CFD) and was estimated to be less than 60 ps.…”

Monte Carlo simulation for microchannel plate framing camera

“…4 The introducing time for each of the three electrons range from 0 ps to 2W ps, increased by a step of 0.1 ps. While the gating pulse with a width of 300 ps and an amplitude of 1 kV is applied to the MCP microstrip line, the G͑t͒ can be obtained with Monte Carlo simulation.…”

“…Then, the electron cascade in the MCP can be approximated by the behavior of a single microchannel. 4 The secondary electron yields, energies, and emission angles are the most important parameters in the simulation. The secondary electron yield is determined by the energy and incident angle of the primary electron.…”

“…Energy conservation is considered in this work to ensure that the sum of the secondary electron emission energy from any given impact is less than the energy of the primary electron. 4 The emission angle of each secondary electron is assigned by sampling from a cosine distribution, and the most probable angle of emission is along the surface normal to the channel wall.…”

“…4,5 Considering that the laser pulse width has effect on the experimental exposure time, we simulate the experimental exposure time varying with laser pulse width. Furthermore, the gain characteristics of the MCP are simulated, while the gating pulse width is not more than the electron transit time.…”
