| |
| − | ** Thunderstorms affect operation; root causes are not known. Possible causes (Jay): 1. u-phonics induced by the thunderstorms, C-100 cryomodules not adequately damped for 10-80 Hz vibrations, coupled to waveguides to upstairs. 2. Imperfect grounding. 3. micros electrical discharges affecting low level RF. 4. Long helix master RF cable running to south linac in water-filled trough.
