Abstract :
Mechanical vibrations of the superconducting interaction region triplets have been identified as source of horizontal beam jitter around 10 Hz in the Relativistic Heavy Ion Collider (RHIC). Therefore, cold masses inside one triplet cryostat have been equipped with accelerometers to further investigate the phenomenon. Additionally, helium pressure transducers have been installed to determine helium pressure oscillations as a possible primary vibration source. Recent results will be reported.
