摘要
本文着重讨论微通道板的噪声因子与首次碰撞时二次电子发射系数的关系。研究表明,在微通道极输入端通道内蒸镀适当深度的高二次发射系数的氧化镁材料,能显著地降低噪声因子。
Relationship between the noise factor of microchannel plate and the secondary electron emission coefficient during the first collision is discussed detailly. MgO material coated in microchannel plate input channel with suitable dept high secondary emission coefficient, can reduce obviously noise factor.
