Numerical calculations of the microwave threshold in the MAX IV 3 GeV ring
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
