Abstract :
Microchannel electron multipliers with tilted structures are simulated using the Monte Carlo method. Gains of secondary electrons are calculated for different structures of the electron multiplier. For a short tilted cylindrical channel of the electron multiplier, a maximum gain is achieved greater than 104 at a tilt angle near 25°. The maximum gain is about 103 times larger than that of the nontilted channel. An explanation for the improvement of gain in tilted channel is suggested
