A key challenge in particle accelerators is achieving high peak intensity. Space charge effects are strongest at injection and typically limit the achievable peak intensity in a ring. The beam stacking technique can overcome this limitation by accumulating a beam at high energy, where space charge is weaker. It also allows the user cycle and the acceleration cycle to be decoupled. In beam...
The neutron yield of the neutron source based on the 18MeV/1mA high-intensity cyclotron developed by the China Institute of Atomic Energy (CIAE) has reached 7×10^13 n/s and has been successfully applied in high-resolution neutron imaging and Boron Neutron Capture Therapy (BNCT) experiments. Precise and quantitative start-to-end beam dynamics simulations facilitate a better understanding of the...
Cyclotrons for isotope production and proton therapy are becoming increasingly compact and widely used. The main trend is reducing size by increasing the magnetic field strength through superconductivity. I propose an alternative approach: instead of increasing the magnetic field, switch to a different scheme—raise the RF system frequency, making the system more compact. Additionally, by...
