Simulation of Quasi-Adiabatic Beam Capture into Acceleration at the Nuclotron
No full textThe routine RF system being used at the Nuclotron allows one to inject the beam at ramping magnetic field with following acceleration at constant amplitude of accelerating voltage. At these conditions at least a half of the particles circulating in the vacuum chamber after injection is not captured in longitudinal acceptance. At the same time vacuum chamber sizes permit to extend the momentum spread of the beam enough to make gymnastic with it inside the stable zone of longitudinal phase space on the flat magnetic field at injection. A quasi-adiabatic capture was considered for increasing the Nuclotron beam intensity. Simulation of such a kind of process with subsequent acceleration was performed. It was shown that in this case it is possible to capture and accelerate up to 100 % of the injected beam
CONCEPTUAL DESIGN OF A 240 MeV SUPERFERRIC SEPARATED ORBIT CYCLOTRON *
No full textAbstract A conceptual design of the Separated Orbit Cyclotron (SOC) for the proton energy of 240 MeV based on the use of superferric magnets (dipoles and quadrupoles) is presented. Superconducting RF cavities are used as well. The beam intensity is determined by, but not limited to the 500µA available from the IBA "Cyclone-30" cyclotron to be used as the 30MeV injector. The electrical power draw of the helium refrigerator is 250kW
Control of the beam-internal target interaction at the nuclotron by means of light radiation
Get PDFAbstract The light radiation from various internal targets at the nuclotron can be utilized for the operative control and time optimization of the interaction intensity of the beam. The examples presented in the paper illustrate information about the space characteristics of the circulating beam during one cycle of the accelerator run at the stages of injection, acceleration and during the physical experiments, respectively
