【 摘 要 】

Horizontal beam vibration around 10 Hz in the Relativistic Heavy Ion Collider (RHIC) have been identified and the possible sources to cause this vibration have been investigated. To determine the helium pressure oscillations as a possible primary vibration source, helium pressure measurements were carried out in the five cryogenic transfer lines at two valve boxes and six lead ports at one triplet cryostat for both magnet rings.
