Abstract :
Capillaries with metal surfaces can improve the transmission of thermal and cold neutrons for focusing devices on account of their greater critical angle and, therefore, greater angular acceptance than glass capillaries. 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 experimental results for glass capillaries and with results of computer simulations of the measurements.
