OPTICAL CHARACTERISTICS OF A MECHANICAL NEUTRON MONOCHROMATOR WITH HELICAL SLOTS
The expression of the function f( lambda ) defining the transmission of a mechanical monochromator with helical slots when the incident neutron beam is limited by a Soller collimator was calculated. The influence of the total reflection from the collimator walls upon the function f( lambda ) was also studied. A mechanical monochromator with helical slots, devised for the suppression of the higher-order Bragg reflections from a crystal, is described. Measurements with this monochromator have served to check the calculations. (auth)
