Comment raith SNF 2009-02-18 14:01:09: larger than normal vibration signature evident in Ebeam Lab

Greetiings:
since recent repairs were effected to the water cooling loop we have been observing larger than  normal vibration signature evident on the RAITH 150 system.  This may be due to a worn bearing in the air handler above this lab, a facilities issue, ot due to a new source in or near the Ebeam Lab.
