Abstract

One year experience of dc H(-) source operation at 2 MeV tandem accelerator is described. The source delivers H(-) ion beams with controlled current in the range of 1-8 mA and energy up to 25 keV. Normalized 1 rms emittance for 8 mA beam is less than 0.2 pi mm mrad. Negative ions are produced on the cesiated anode of the Penning discharge, driven by plasma injection from the hollow cathode inserts.

摘要

描述了在2 MeV串列加速器上进行直流H(-)源运行的一年经验。该源可提供电流可控的H(-)离子束，电流范围为1 - 8 mA，能量高达25 keV。8 mA束流的归一化均方根发射度小于0.2π mm mrad。负离子在潘宁放电的铯化阳极上产生，由空心阴极插入件的等离子体注入驱动。
