Presentation showing a summary of simulated "desired" beam sizes for the ATF test beam. Plot summarizing the predicted melted surface against beam parameters.
The desired beam sizes will have a beam area of less than
60 um^2 but only for a top charge of 2E10 e-, if that charge can't be achieved then the beam are shall be smaller than
50 um^2, combining (if possible) a
round beam with a
cigar shaped beam to compare damage shapes.
