OUTLINE
Background Requirements Test results Future tests
Please note information is limited until Hitachi present results in SC conference in September this year

Background and ObjectivesWall plug to RF efficiency
Pushing modulator designers to decreaseRise time and fall time
Wasted energy!
Recent ongoing program to increase klystron efficiency
from ~44% to >>65%Reduces power requirements and cost of modulators
What about solenoid power consumption ?

• Magnet now at CERN• Will confirm magnetic
measurements in coming weeks• Waiting for ‘warm’ counter coil
• Collaboration with Scandiova• Removal of ‘warm’ solenoid
power supplies from Xbox2 modulator
• Integration of SC magnet interlocks and power supplies
• Integration of klystron with SC magnet and modulator
Full results will be presented in SC magnet conference in September
