本文报导了一个强直流输出的双等离子体氢(氘)离子源.当引出电压为18kv 时,可输出100mA 的氢离子流.利用90°偏转磁分析器对引出束流的质量成分作了分析,质子比可达到64%.采用多缝探针法和离子束感光法测定了束流发射度和亮度.在输出流强为50mA,束能量为16kev 时,束流的归一化发射度(相空间面积×βΥ/π)和归一化亮度分别为0.48mm·mrad 和4.4×10~6A/cm~2·rad~2.在不同的工作参数下,测定了源的运行特性.
In this paper, a double plasma hydrogen (deuterium) ion source with strong DC output is introduced. When the voltage is 18kv, a 100mA hydrogen ion current can be output. The mass fraction of the outgoing beam is analyzed by a 90 ° deflection magnetic analyzer , And the proton ratio can reach 64% .Beam emission and brightness were measured by multi-slit probe method and ion beam sensitization method. When the output flow intensity was 50mA and the beam energy was 16kev, the normalized emittance Phase area × βY / π) and normalized luminance were 0.48mm · mrad and 4.4 × 10-6A / cm ~ 2 · rad ~ 2, respectively. The operating characteristics of the source were measured under different operating parameters.
