Abstract :
In low energy storage rings with a high current, collective effects can make the real bunch length, transverse emittances and beam lifetime notably different from the ones designed on the basis of single particle dynamics. The storage ring EUTERPE is a low energy ring with a nominal beam energy of 400 MeV and with an injection energy of 75 MeV. The estimation of collective effects in this ring is reported in this paper. The dependence of several collective effects on various machine parameters, limiting effects on the bunch size and current for several optical options and possible improving measures are discussed. The results indicate that an equilibrium transverse emittance of 8.5 nm.rad with a beam current of 100 mA in a high brilliance mode is achievable, which is near the natural emittance. Collective effects have no obvious adverse effects on low energy injection in the EUTERPE ring
