•The current injection bump dogleg (ORBUMP)
magnets can ramp at 7.5
Hz, with a substantial temperature rise.
•Need to go to 10 to support MiniBooNE and
NuMI.
•2 spares for the 4 (identical) magnets. Most
likely failure mode probably
repairable.
•Considering new design which will stretch
existing magnets further
apart, which will lower their current, but will require a pulsed injection septum between the first
two.
•Can new design incorporate injection improvements??
•Some power supply issues as well:
–One full set of replacement SCR’s for the
switch network.
–New switchbox being designed, but needs
attention (or order more spare SCR’s).
–No spare for charge recovery choke.
