    (Received January 8, 2008)

    At the extraction part of J-PARC 3 GeV Rapid Cycling Synchrotron, a race-track bellows is required between the vacuum chamber of extraction septum magnet 1 and 2, because there is no space to install a circular bellows. However, formed titanium bellows with race-track shape have never been fabricated. Small size formed titanium race-track bellows were fabricated. Characteristics of them were measured and evaluated. Spring force measurements, expansion/contraction repetition life test, vacuum heating test and He-gas leak test were performed. The characteristics of the race-track bellows are satisfied with our use conditions. We obtained a prospect that actual size race-track bellows could be used.
