Report on experiments performed with mixed or analyzed deuterium ion beams incident on TiT targets at the neutron therapy facility Hamburg-Eppendorf. Bombarding a TiT target area with all separated atomic and molecular ions of an analyzed deuterium ion beam at different beam spots, the "initial" half-life of the used tritium target increases with a factor of more than three as against the half-life obtained with a mixed deuterium ion beam at a single beam spot. In this case, the effective target current is not reduced and in the same order as that for a mixed deuterium ion beam. Using the atomic deuterons only, the increase of the "initial" half-life is far longer yet, but the loss in target current is about 50% dependent on the reduction of molecular deuterium ions. These facts are most important for the economy of this type of neutron therapy facilities clinical work.
关于在汉堡 - 埃彭多夫中子治疗设施中，用混合或分析过的氘离子束轰击钛靶进行实验的报告。在不同束斑处，用分析过的氘离子束中所有分离的原子和分子离子轰击钛靶区域，所用氚靶的“初始”半衰期相对于在单个束斑处用混合氘离子束获得的半衰期增加了三倍多。在这种情况下，有效靶电流没有降低，且与混合氘离子束的有效靶电流处于同一量级。仅使用原子氘核时，“初始”半衰期的增加幅度更大，但靶电流损失约为50%，这取决于分子氘离子的减少。这些事实对于此类中子治疗设施临床工作的经济性至关重要。
