测量了用于ADS研究的强流ECR离子源脉冲束发射度,离子源引出120mA/75keV的强流质子束,并通过调制微波电源实现离子源引出束流的脉冲化,脉冲频率50Hz,脉冲宽度1ms,上下沿约20～30μs。测量装置如图1所示。
The pulsed beam emissivity of a strong current ECR ion source used in ADS research was measured. The ion source extracted a strong current proton beam of 120 mA / 75 keV and pulsed the ion source extraction beam by modulating microwave power. The pulse frequency was 50 Hz and the pulse width 1ms, up and down along about 20 ~ 30μs. Measuring device shown in Figure 1.
