【 摘 要 】

Synopsis In order to obtain an intense ion beam in air, we have developed the He capillary, which is a normal glass capillary filled with low pressure He gas. The energy spectra of an ion beam transmitted via the He-capillary with and without He have been measured. An enhancement of the peak intensity and suppression of low energy components have been observed for the He- capillary.
