MICROWAVE ELECTRONICALLY VARIABLE ION BEAM TIME DELAY DEVICE STUDY.
Abstract
Studies of the ion-beam delay line this quarter were in the areas of beam transmission through a depressed drift tube and the theoretical analysis of space-charge waves on a drifting multivelocity beam. The preliminary results on transmission of a lithium ion beam through a 6 cm tube shows that substantial currents can be passed even without special focusing methods. The theoretical analysis of Landau damping on a multi-velocity beam has clarified the conditions on the parameters that must be satisfied for undamped wave propagation to occur. For a desired beam current and fixed energy spread this condition sets a lower limit on the beam energy for undamped propagation; this lower limit increases linearly with the operating frequency and it could be one of the more improtant basic limitations on the maximum achievable delay of an ion beam delay device at microwave frequencies.
