Abstract
Transverse noise (stochastic) blow-up of the beam in the course of slow particle extraction at the magnetic-field flat bottom in the U-70 synchrotron at the Institute for High Energy Physics has been investigated. The diffusion equation is stated, and the feasible time scale of the transverse (horizontal) noise blow-up of the beam is estimated. The depth of the beam overshoot inward of the edge of the inner energy-degrader target is determined, and the relevant requirements for the target geometry are formulated. Results of experiments with the carbon beam in the U-70 machine are presented.
