Improving the design and analysis of superconducting magnets for particle accelerators

Abstract

MrnI5UTbetween accelerator physicists and magnet builders was important in leading field quality improvements in the direction most critical to the performance of machine.Discussions with the engineers in RHIC magnet production group, in particular with Mr. M. Anerella and Mr. E. Kelly, were important in incorporating various design features in magnet construction in an efficient manner. Several drawings in this manuscript are provided by the design oftice.

Study of the first Mexican RF linear accelerator

“…where B ro is the magnitude of the field due to the fundamental harmonic at the reference radius R r (1.5 cm for this calculations) on the midplane, b n and a n are the normal and skew multipoles [19]. For the 5 T/m gradient, the allowed higher order multipoles b 5 , b 9 and b 13 [20] are kept below 1 unit, and field uniformity within 1 %.…”

Magnetic field characteristics from HTS quadruple magnet of in-flight separator for a heavy ion accelerator

“…If we define the amplitudes of n th magnetic field component as B ρn and B φn , they can be expressed by (2) B ρn and B φn are constants if the radius ρ is fixed and must be same theoretically. …”

“…Quadruple magnets are widely used in accelerator for focusing the transporting beams of particles [1,2] and the field uniformity in good field region reflects the quality of the quadruple magnet. However the requirements for the field quality in the good field region of quadruple magnet can be different between applications.…”
