高电荷态注入器(HLI)的CAPRICE电子回旋共振(ECR)离子源作为GSI UNILAC的标准注入线，现已在一年中的所有束流时间段内永久运行。因此，配备相同版本CAPRICE的ECR试验台主要用于准备工作。各种元素的离子束被要求覆盖长达六周的束流时间周期。除了在各种气体下稳定可靠地运行外，我们的高温烤箱的应用已成为所有固体材料的标准方法，这些材料的蒸汽压在800到1500−°C之间达到10 3 mbar。它不仅适用于纯金属样品，而且还适用于专门生产的同位素氧化锌样品，提供稳定的68Zn10+离子束。或者，为高蒸汽压材料建造了低温蒸发器，并用于生产Se和Zn离子。在烘箱和蒸发器法方面取得的经验将是值得借鉴的。
The Caprice electron cyclotron resonance (ECR) ion source of the high charge state injector (HLI) as standard injection line for the UNILAC at GSI is now in permanent operation during all beam time periods of a year. So the ECR test stand which is equipped with the same version of Caprice mainly has to be used for preparatory work. Ion beams of a great variety of elements are demanded covering beam time periods of up to six weeks. Besides the stable and reliable operation with diverse gases the application of our high-temperature oven has become a standard method for all solid materials attaining a vapor pressure of 10−3 mbar between 800 and 1500 °C. It has been operated not only with pure metal samples but also with especially produced isotopic zinc oxide samples providing a stable beam of 68Zn10+ ions. Alternatively a low-temperature evaporator was constructed for high vapor pressure materials and was used for the production of Se and Zn ions. Experiences gained with the oven and evaporator method will ...
