【 摘 要 】

The transmission of 1MeV proton microbeam through aTeflon microcapillary was studied. Using the suitable combination of the capillary temperature and beam intensity we identified three different regions in the transmission as a function of time. In the third region stable guided transmission was obtained where the dominant contribution of the transmitted protons did not suffer energy loss.
