DEVELOPMENT OF COLD NEUTRON PULSER FOR DELAYED CHOICE EXPERIMENT

The delayed choice experiment was done using the cold neutron spin int erferometer of Jamin type arrangement which is installed at the JRR-3M of JAERI. ''A multilayer polarizing cold neutron mirror placed in the pulsed magnetic field'' is called a multilayer cold neutron pulser, o r, in short, a cold neutron pulser. The switching function of the cold neutron pulser was used for producing the condition of whether or not the magnetic mirror is placed for the polarized neutron. It was shown that the cold neutron pulser is applicable to a cold neutron optical switch for the delayed choice experiment. (C) 1998 Elsevier Science B. V. All rights reserved.
