Automated Control System for Smith—Garren Curves Measurement
Publications, 12 November 2019
We are glad to bring to your attention a new preprint «Automated Control System (ACS) for Smith—Garren (SG) Curves Measurement» E9-2019-46 published by the JINR Publishing Department. The authors of the work are Amirkhanov I. V., Kiyan I. N., Sulikowski J.
The Smith–Garren (SG) curve is dependence of beam current on the main coil’s current for different radii in an isochronous cyclotron. The SG curves are used for calculation of phase motion of accelerated particles in absolute and relative values followed by calculation of phase-energy integral. The results of beam dynamics calculations are used for correction of mean magnetic field to the isochronous one with accuracy better than ±3 G followed by detection of an optimal value of the main coil’s current, and for calculation of extraction efficiency of accelerated beam.
