摘要：
The transmission of 3 MeV protons and 16 MeV O5+ ions through a single cylindrically-shaped insulating macrocapillary glass has been investigated in a preliminary study. The capillary had a diameter d = 0.18 mm and length l = 14.4 mm, giving an aspect ratio l/d = 80. The sample was mounted on a goniometer to permit precise positioning with respect to the incident beam direction. Results show that 3 MeV protons transmit through the capillary without energy loss at small tilt angles (near zero), and the 16 MeV O5+ ions show transmission through the sample also with little energy loss at the same small tilt angles and little change in their charge state (similar to 1%). For a larger tilt angle (= 1.5 degrees), appreciable losses in energy occurred for incident O5+ and the ions changed their charge state up to 7(+).
