Computer programs utilizing Legendre functions and elliptic integral functions have been written to aid in the design of solenoid rnagnets.The field inside an axisyrmnetric magnet• can be expanded in a converging power series of Legendre functions.The Legendre function approach is very useful for designing solenoid magnets with a high degree of field uniformity.This approach has been programed on the LBL CDC 7600 computer so that one can design an axisyrmnetrk magnet which meets any desired field structure.This report presents two examples of computer designed solenoids.A computer program utilizing elliptic integral functions was also written for theLBL CDC 7600 computer.This method was used in a computer program to verify the results obtained from the Legendre approach and for field calculations within the conductor.The elliptic integral field calculations within the conductor showed that thin solenoids produce field peaking at the ends of the magnet.Computer data is generated for various magnet geometries and compared with theoretical predictions.Computer results and theoretical prediction both show that field peaking is reduced for longer coils, increased for -ivthinner coils and field peaking is a logarithmic function of length, thickness and radius.
