Three Dimensional Field Analysis of Helical Snake Magnets for RHIC
- Institute of Physical and Chemical Research (RIKEN), Saitama (Japan)
RIKEN - Brookhaven National Laboratory (BNL) Spin Project is in progress. The accelerator aspect of this project is to accelerate polarized proton beams to the top energy of Relativistic Heavy Ion Collider (RHIC). For this purpose, it is necessary to develop super conducting magnets of helical structure as a Siberian Snake for the control of the polarized beams. In this design work, it is shown that the two dimensional analysis was insufficient to estimate the multipole components, fringing field and longitudinal component of the field. Then we calculate three dimensional (3D) magnetic field using the computer code TOSCA. Also the analysis of beam orbit and spin motion of polarized protons in Siberian Snakes are done using the results of 3D field calculation.
