Abstract :
There are effects in the Medium Energy Booster (MEB) of the SSC which will lead to growth of the transverse beam emittance. Among them are space charge, decoherence due to residual chromaticity and nonlinearity of field, coherent instabilities, etc. This paper numerically estimates the strength of these effects on the beam stability and the emittance growth. To ensure that the emittance growth is within the stringent emittance budget of the SSC accelerator complex, a few feasible cures have been planned. Their improvements on beam quality are also described in this paper
