Guiding of a Slow Positron Beam with a Glass Capillary
A focusing (guiding) technique of the ion 1 and muon 2 beams with glass capillaries has been intensively studied in recent years. This beam focusing technique has practical advantages. For example, the diameter of the focused beam is defined clearly by the diameter of the capillary exit and does not depend on the beam parameters such as intensity, energy and emittance. The exit of the capillary can be covered by a thin glass wall. Hence, we can irradiate the focused beam to samples which can not kept in vacuum like living human cells 3. In addition, the beam focusing system smaller than conventional electric and/or magnetic beam optics. Though the capillary focusing technique has some interesting futures as described above, this technique has never applied for focusing of a slow positron beam. We started studying possibility of this technique for guiding and focusing of a slow positron beam.
