查询词典 electron tube

By comparing the electron gain of the prepared silicon microchannel plate with conventional one,we found the electron gain of Si MCP was larger than glass MCP.Though there were some problems to be solved in the manufacture of electron multiplier of Si MCP,it was expected that Si MCP would be a new approach to enhance the performances of MCP and the quality of image devices.

This paper introduces the studies of the ultra-short Thomson scattering X-ray source at the accelerator laboratory of Tsinghua University in recent years. Properties such as the photon yield,the pulse length and time jitter of the produced photon pulse were predicted theoretically from the parameters of the electron bunch and the laser pulse,and the scattering angle. Preliminary experiments were successfully carried out with a 16 MeV backward-traveling-wave accelerator and the ns-Q switched laser provided by China Academy of Engineering Physics. This paper also introduces the 1.6-cell electron gun that was fabricated on site and the experiment with high RF power including the measurement of the electron bunche parameters. Based on these,we have designed an X-ray source,which is now under construction.
