Summary, in English

Simulations of collective effects in the MAX IV 3 GeV ring were done with the tracking code mbtrack. The code is a 6D macroparticle tracking code performing transformations under the influence of various wakefields. Each bunch is presented by a number of macroparticles which are sorted into bins according to their longitudinal position. The discrepancy in the results for the microwave instability was noticed depending on binning and number of particles. This report summarizes the studies of the microwave instability threshold dependence on binning and number of particles, and converged ‘true’ threshold value is obtained.
