accelerator electrode造句

• Accelerator electrode geometry and materials are also open areas of research.
• Ions emerging from the exit cathode are accelerated through the potential difference between the exit cathode and the accelerator electrode.
• In order to prevent these secondary electrons from being accelerated back into the ion source, the accelerator electrode is biased negative with respect to the target.
• These electrons are collected through the liquid metal column by the channel walls, and the positive ions are accelerated away from the liquid through a gap in the negative accelerator electrode by the same electric field that created them.
