The numerical simulation of the [sup 48]Ca[sup 5+] ions beam transport along the U-400 cyclotron's injection line has been carried out. Space charge effects of multi-charged ions spectrum extracted from ECR-source and the longitudinal beam compression influence of two bunchers (sine and line types) on the transverse beam dynamics have been taken into consideration in the process of the beam transport optimization. The simulation results are compared for two injection line schemes: of presently utilized line and its reconstructed variant. The injection line reconstruction does not require any new ion-optic elements. It assumes the exception of the 102° horizontal bending magnet from the present injection line. Eventually this reconstruction will give meaningful transport line shortening. According to produced simulation the expected transmission efficiency from the ECR-source to the cyclotron's spiral inflector entrance along the reconstructed injection line will be essentially increased, as well as appreciably more [sup 48]Ca[sup 5+] beam intensity level will be provided.

    We have proposed a double drift bunching scheme where one can obtain a bunching effect equal to that of a sixharmonic buncher by using only two harmonics mixed in optimum proportions. In this case one has to apply voltages with frequencies ω and 2 ω (instead of only ω) on the first...

    A vertical beam loss on the extraction elements of the KS00 cyclotron has been observed during commissioning of the Coupled Cyclotron Project. The cause was found to be the misalignment of coils, and the coil shift vertically about 1 mm made a correction. The vertical displacement of a 9.5 MeV/u...
