Review of Lemons Et Al.

Lemons demonstrates that in good conditions a LG01 beam is an ideal choice for mitigating MBI.It is noted however that mechanical noise can lead to the overlap of the electron beam with the beam maxima.Other modes are not as susceptible to this problem, so there is a trade off between ideal heating performance and jitter mitigation.One alternative considered is a Hermite-Gaussian orthogonally polarized CV beam.The performance of an HG beam will be worse than that of an LG beam due to the wider beam waist and lower e-beam interaction for higher elevation angle magnitudes.Due to the lack of an E-field maxima in one plane the performance of an HG beam may be superior in an environment where transverse jitter is of major concern, particularly if the jitter is confined to the same plane as the null of the HG beam.Higher order beams with more sophisticated transverse distributions should also be considered .
