Description
The neutron imaging instrument CONRAD at HZB was upgraded recently. The neutron guide system was replaced by a new one based on super mirrors. This has reflected in higher neutron flux and larger beam at the sample position. The capabilities of the instrument in the field of energy-selective imaging were strengthened by construction of new double crystal monochromator and installation of velocity selector. The parameters of the devices were studied and procedure for their calibration was developed. Effects like wavelength and intensity inhomogenieties were observed and analyzed. New method for energy selective imaging using the wavelength gradient over the image plane due to the mosaic of the monochromator crystals was developed. The parameters of the energy-selective capabilities of the CONRAD-2 instrument will be presented and recent will be discussed.
