Abstract
A thin, flexible, hollow fiber capable of transmitting ionizing radiation. Ionizing radiation enters the fiber through entrance pupil (10) and travels through the hollow interior of fiber body (20) by reflecting and scattering off the inner wall of the fiber, frequently at grazing incidence angles. Fiber body (20) is covered at one end by thin film cap (30) which is thin enough to be at least semitransparent to ionizing radiation, but which is also strong enough to allow air to be withdrawn from fiber body (20) at the opposite uncapped end. Small obstructions (32) at the exit end of the fiber can be used to spread the beam of ionizing radiation to a desirable width. A flexible fiber capable of transmitting ionizing radiation has important applications in medicine for the radiation therapy of tumors. Applications also exist in communications and other fields.
