Experimental demonstration of the induction synchrotron

Area of Science:

• Particle Accelerators
• High-Energy Physics
• Accelerator Technology

Background:

• Future neutrino factories and hadron colliders require advanced accelerator concepts.
• Transverse space-charge limits restrict charge acceleration in conventional synchrotrons.
• Superbunch technology offers a potential solution to increase accelerated charge.

Purpose of the Study:

• To experimentally demonstrate the feasibility of the induction synchrotron.
• To validate the concept of superbunch acceleration within an induction synchrotron.
• To assess the performance of a novel induction acceleration system.

Main Methods:

• Utilized a newly developed induction acceleration system, replacing traditional radio-wave devices.
• Injected a single proton bunch from a 500 MeV booster ring.
• Employed barrier bucket created by induction step voltages for particle capture and acceleration.

Main Results:

• Successfully accelerated a proton bunch from 500 MeV to 6 GeV within the KEK proton synchrotron.
• Demonstrated the capability of the induction synchrotron to support a superbunch.
• Validated the effectiveness of the induction acceleration system in overcoming space-charge limitations.

Conclusions:

• The induction synchrotron is a viable concept for next-generation particle accelerators.
• Superbunch acceleration via induction is achievable and efficient.
• This technology holds promise for future neutrino factories and hadron colliders.
