ZAP AND ITS APPLICATION TO THE OPTIMIZATION OF SYNCHROTRON LIGHT SOURCE PARAMETERS

A new computer code, ZAP, has been written to study the influence of various collective effects on the performance of electron storage rings.In particular, the code can evaluate the equilibrium emittance of a ring including the effects of intrabeam scattering.Examples are presented of utilizing the code to optimize the design of storage rings for the purposes of a thirdgeneration synchrotron radiation source and a high-gain free-electron laser.In addition, the importance of the intrabeam scattering emittance blowup to the issue of low energy injection is discussed.Such considerations will be necessary to optimize the design of compact synchrotrons now being studied for use in x-ray lithography.To verify predictions of the code, comparisons are made with experimental measurements of low energy beam emittance taken from the Aladdin storage ring; reasonable agreement is obtained .
