束流发射度 meaning in English

beam emittance

Beam emittance measurement with modified three gradient method
用修正三梯度法测量束流发射度
Simulation on the a - magnet of 30mev linac is also done with the gpt code ; the movement picture of electron beam in a - magnet is presented ; the change of beams emittance , the compression effect of bunch length , change of energy dissipation and achromatic angle of true a - magnet are explored . this chapter mainly introduces some characteristics and properties of the main accelerate stage in 30mev linac system
利用gpt程序对30mevlinac中的-磁铁进行了动力学模拟，给出了电子束在-磁铁中的运动图像，研究了注入器输出束流经过-磁铁后束流发射度的变化、束团长度的压缩效应、能散度的变化以及-磁铁实际的消色散入射角。
