WEPO003	Beam Dynamics in a New 230 MeV Cyclotron	208
	O. Karamyshev JINR, Dubna, Moscow Region, Russia
	A new cyclotron for proton therapy concept is a compact, but non-superconducting accelerator, that is simple, but cheap. Proposed concept uses 4 sectors with double spiral design and 4 RF cavities operating at harmonic 8, making the central region and extraction a challenging task that needs to be carefully simulated. High injection and extraction efficiency is presented.

THBO01	A New Concept Of Cyclotrons for Medical Applications	274
	O. Karamyshev JINR, Dubna, Moscow Region, Russia
	Demand for cyclotrons for medical applications is growing rapidly. Cyclotrons delivering proton beams from 15 MeV up to 230 MeV are being used for isotopes production and proton therapy. Author proposes a con-cept that allows to significantly reduce cost of cyclotrons by making them more compact and power efficient without using superconducting coil. In the proposed design ratio between azimuthal length of sectors and valleys is over 3 to 1, with RF system operating at high frequency and acceleration at harmonic mode of 2 times the number of sectors. Compact size is achieved not by increasing the magnet field level, but by reducing the coil and RF system dimension. Cyclotrons will have 4 sectors and 4 rf cavities operating at harmonic 8 with 1.55 T mean field and accelerating frequency 180 MHz.

Acceleration is performed at the fourth harmonic mode of the accelerating radio-frequency (RF) system consisting of four cavities located in the cyclotron valleys. The accelerator will use an internal Penning type source with a hot cathode. Particular attention is paid to extraction, as it must have a high extraction efficiency.
