摘要：

Straight and curved glass capillaries were tested for the guiding of 8 keV Ar8+ ion beams. The straight capillary was about 50 mm long and 0.87 mm/1.1 mm in inner/outer diameter. One of the two curved capillaries was similar, but was curved with a 270 mm radius. The other was 53 mm long, had diameters of 2.34 mm/2.99 mm, and was curved with a 150 mm radius. The corresponding bending angles of the two curved capillaries were 9.6 degrees and 17.5 degrees, respectively. Transmission through the straight capillary disappeared when the tilt angle was larger than 5 degrees. The curved capillaries guided the ion beams into their corresponding bending angles, which were much larger than 5 degrees, with transmission efficiencies of a few tens percent. This demonstrates the possibility of developing a new scheme of simple small beam deflectors and related beam optics. (C) 2014 Elsevier B.V. All rights reserved.
