Outline of Final Research Achievements

Permanent magnet based dipole magnets have been developed for next generation light sources. Permanent magnet is advantageous over conventional electromagnet in terms of power consumption and less power supply related failures. There are, however, reasons why such magnets have not been chosen as main magnets for light sources, such as field quality, temperature dependence of magnetic field, adjustability of magnetic field, and demagnetisation due to radiation. We had designed magnetic circuit for solving these issues, and the magnet was fabricated. As a result, it was experimentally verified that the newly designed dipole magnet work almost fully as expected , and so far nothing has prevented us from going for permanent magnets. In fact, a discussion on a feasibility of such magnets for the latest next generation light source project in Japan has seriously started, other positive comments have been given from outside. Further study will be continued.
