  1. HDS at X-band Parameters fixed in the optimization (same as in H60vg3): Frequency = 11.424 GHz Bunch charge = 7.5*109*e= 1.2 nC a/lambda = 0.17 Transverse wake amplitude at the second bunch < 0.2 V/pC/mm/m Averaged loaded accelerating gradient = 55 MV/m In order to have no more than 1 breakdown in 10 h: Pin * tP1/2 < 1100 [MW*ns1/2]
