Description
The final-focus solenoids of the round-beam e+e- collider VEPP-2000 can cause stopbands in the betatron tune plane. This specific stopband domain limits the available tune space in the most important region above the integer tunes. We present a theoretical study of the combined effect of the decompensated solenoids and the parametric resonances at the integers. The results are compared with numerical investigations of this combined effect. Experimantal data on scanning of the VEPP-2000 tunes showed the limits of the available tune domain which agree with the theoretical expectations.
