noun
- plural of dynode; electrodes in electron tubes that emit secondary electrons when struck by primary electrons
Usage: technical; electronics
Examples
- The photomultiplier tube contains several dynodes arranged in sequence.
- Each dynode amplifies the electron signal by releasing multiple secondary electrons.
- The voltage between dynodes determines the amplification factor.
- Modern dynodes are often made from materials with high secondary emission coefficients.
- The electron cascade moves from one dynode to the next in the tube.
- Damaged dynodes can reduce the sensitivity of the detection system.
