New type of versatile neutron diffractometer with a double-crystal monochromator system
Original language description
Properties of a special double-crystal (DC) monochromator employing bent-perfect crystals of Si in (1, 1) and (n, m) settings are presented. The first monochromator was the bent Si(111) crystal (4 mm thickness) and the second one was in the form of a sandwich consisting of two bent Si (111) and Si(220) slabs (2 and 1.3 mm thickness, respectively). It has been found that by a simple exchange of diffraction conditions on the second monochromator one can use either Si(111) + Si (111) bent crystals in (1, 1) setting providing good luminosity and worse diffractometer resolution or Si(111) + Si(220) bent crystals in quasi-dispersive (n, m) setting providing very good diffractometer resolution and correspondingly weaker luminosity. It has been found that besides an excellent focusing and reflectivity properties of the dispersive double-bent-crystal setting the obtained monochromatic neutron current is sufficiently high for diffraction experiments even at the mediumpower research reactor.
