Abstract :
The stretcher mode of KSR has been experimentally tested. Up to now, a beam spill longer than 8 seconds has been attained by reducing RF knockout power. Improvement of extraction efficiency will be realized by ramping of betatron tune and formation of closed-orbit-distortion without the effect of non-linear sextupole magnets to make an aperture minimum at the first septum for extraction
