机译：Use of the Kalman filter in signal processing to reduce beam requirements for alphahyphen;particle diagnostics
In principle, a probing beam of neutral atoms can be used to measure the velocity distribution of fast alpha particles confined in an ignited fusion plasma. In this article we discuss beam modulation techniques and a compatible signal processor based on a Kalman filter that together can provide, in one hypothetical case, a reduction of a factor of 10 in the beam current required, as compared with that required for a straightforward measurement with a dc beam.
