Results of 2DMonte-Carlo simulations of development of QED cascades in intense uniformly rotating electric field are presented. We consider cascades produced by initially slow electrons. It is shown that under such conditions stable cascade development starts at field strength of the order of 1% of the QED critical field 5 × 1029W/cm2. The cascade yield is growing exponentially in time. Several characteristics of cascade, including average energy of particles and their mean free path times are computed. Our results are in good agreement with recent estimations [A. M. Fedotov et al., PRL 105, 080402 (2010)].
