Abstract
Capillaries with metal surfaces can improve the transmission of therma l and cold neutrons for focusing devices on account of their greater c ritical angle and, therefore, greater angular acceptance than glass ca pillaries. The transmission characteristics of nickel tubes have been measured with both white beam and monochromatic neutrons. Results are given for curved nickel capillaries, and are compared with experimenta l results for glass capillaries and with results of computer simulatio ns of the measurements.
