【 摘 要 】

There are more than 15 years since the transition-jump system (TJS) was installed. Because of the quad steering, which is caused by the beam not being well centered through all the {gamma}{sub T} quads, the TJS has never been used in the operation. Based upon the recent calculation, the short 12 {gamma}{sub T} quad had the worst offset in the vertical direction, and it was lowered 4 mm. Afterwards, the orbit error caused by the {gamma}{sub T} quad steering has been largely removed, and this encourages our efforts of commissioning the TJS to reach its design goal.
