We have aborted Top-up since we have had another beam loss with the same
signature as previous losses. Repairs to the kicker power supply have
not solved the problem and Controls personnel are being contacted to
help in the investigation. The Power Supply personnel believe they have
identified the cause, one of the kickers is occasionally discharging
during the charging cycle, but have not yet identified why this occurs.
We may delay the fill-on-fill to give the Controls and Power Supply
personnel a chance to sufficiently look into the problem, particularly
since we have lost beam on the last two fill-on-fills. We will try and
keep you as up to date as possible.
