| Outline of Final Research Achievements |
Design of a new high-intensity KL beam line in order to be realized a high-statistics rare KL decay experiment in the J-PARC Hadron Experimental Hall, which is planned to be extended, has been performed. Mechanical design and estimation of radiation damage for vacuum windows, which is one of most difficult part, has been proceeded. Also, alignment method of KL beam collimators and effects by material in the KL beam line have been evaluated. Based on these developments, conceptual design and testing requirements have been proposed.
