A simplified vacuum arc design [based on metal vapor vacuum arc (MeVVA) concepts] is employed as a plasma source for a study of a (7)Be non-neutral plasma. The design includes a mechanism for interchanging the cathode source. Testing of the plasma source showed that it is capable of producing on the order of 10(12) charges at confinable energies using a boron-carbide disk as the cathode target. The design is simplified from typical designs for lower energy and lower density applications by using only the trigger spark rather than the full vacuum arc in high current ion beam designs. The interchangeability of the cathode design gives the source the ability to replace only the source sample, simplifying use of radioactive materials in the plasma source. The sample can also be replaced with a completely different conductive material. The design can be easily modified for use in other plasma confinement or full MeVVA applications.
一种简化的真空电弧设计（基于金属蒸汽真空电弧（MeVVA）概念）被用作等离子体源，用于研究（7）Be非中性等离子体。该设计包括一种用于更换阴极源的机制。对该等离子体源的测试表明，使用碳化硼盘作为阴极靶，它能够在可限制的能量下产生约10（12）个电荷。与高电流离子束设计中典型的用于较低能量和较低密度应用的设计相比，该设计通过仅使用触发火花而非全真空电弧得以简化。阴极设计的可互换性使该源能够仅更换源样品，从而简化了等离子体源中放射性材料的使用。样品也可以被完全不同的导电材料替代。该设计可以很容易地修改以用于其他等离子体约束或全MeVVA应用。
