Abstract :
The transverse emittance in the FNAL (Fermi National Accelerator Laboratory) Booster grows at a high beam intensity, in a time less than 100 turns. An examination is made of the possible contributions to the fast emittance growth from coherent instability of the beam envelope. Theoretical analysis, through the use of envelope equations, is employed to predict the dependence of envelope instability on the peak current of the Booster beam. These predictions are compared to the results of multiparticle tracking calculations.<>
