The brightness and intensity of a circulating proton beam now can be increased up to space charge limit by means of charge exchange injection or by an electron cooling but cannot be increased above this limit. Significantly higher brightness can be produced by means of the charge exchange injection with the space charge compensation [1]. The brightness of the space charge compensated beam is limited at low level by development of the electron-proton (e-p) instability [2]. Fortunately, e-p instability can be self-stabilized at a high beam density. A beam brightness booster (BBB) for significant increase of accumulated beam brightness is discussed. Accelerating system with a space charge compensation is proposed and described. The superintense beam production can be simplified by developing of nonlinear nearly integrable focusing system with broad spread of betatron tune and the broadband feedback system for e-p instability suppression .
