用^(27)Al(p,p′γ)^(27)Al瞬发核反应的γ射线产额衡量加速器的能量稳定性

Measurement of energy stability of accelerators by monitoring γ -ray yields of the ^(27)Al(p,p' γ)^(27)Al reaction

报道了用^(27)Al(p,p′γ)^(27)Al瞬发核反应的γ射线产额测量4MV加速器的能量稳定性.并通过更换加速器聚焦磁透镜电源,发现能量稳定性有较大提高.

The energy stability of the 4MV accelerator has been measured by monitoring the r-ray yields of the 27Al(p,p' r )27A1 reaction. The energy stability became better after replacement of power supply for the focusing lens of the accelerator.
