Outline of Final Research Achievements

MgB2 is expected to be applied at 5-30 K using a compact cryocooler as rare-earth meatal free strong superconducting magnets. In this study we have developed reproducible fabrication process for disc-shaped MgB2 bulks with several centimeters in size and trapped field measurement system with GM cryocooler. Trapped field of MgB2 bulks showed several teslas at intermediate temperature which can be easily reached by compact cryocoolers.
