| Outline of Final Research Achievements |
The polarized HD target have been developed to investigate the nucleon structure of proton and neutron in the LEPS beam line of SPring-8. Previously in order to obtain the result of the polarization degree of produced target took three month, this is obstacle for the trial because the trial require a lot of human resource and liquid helium. If the polarization degree is monitored for this three month, it is possible to shorten the period of trial , but it was difficult.
In this research, I have challenged to develop the 1G Hz NMR measurement system with cost of one-tenth what is assumed for monitoring the growth of polarization in the manufacturing process. As a result, it was found that the polarization degree of hydrogen grows in one day, and the trial period is possible to shorten significantly reduce from three months.
