Improvement of the cold neutron beam line (CN-3) in KUR for neutron optical device development

摘要

The cold neutron beam line CN-3 in Kyoto University Reactor (KUR) is being renewed for dedicating to the development of neutron optical devices. CN-3 has a supermirror guide tube with the cross-section of 20 mm (width) x 90 mm (height), and the wide-band neutron spectrum is available. New beam lines are prepared for both time-of-flight (TOF) and monochromatic experiments including a neutron reflectivity measurement. It has a polarized neutron option with a very low magnetic field to cope with polarized neutron devices. In particular. the TOF mode will be used for developing devices, which are suitable for pulsed neutron sources. Cold neutron radiography is also available within a space of 1 m x 0.8 m. A neutron imaging plate system is prepared as the neutron imaging detection. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 11]
