| Abstract |
The new beam position and phase monitors at LANSCE measure the phase of the beam relative to a reference signal from the master reference oscillator. The distribution of the reference signal along the 800 m long linac is subject to thermal effects, and phase drifts of the reference signal are observed to be greater than 15 degrees. We are investigating stabilisation schemes, one of which involves distributing two RF signals of different frequencies. By observing the phase difference between the two signals, the phase drift of the reference signal can be deduced. Initial tests indicate that the reference can be stabilised to within 0.5 degrees using this scheme. In this paper we will present the principles of operation of this stabilisation scheme and results from tests of the system.
