The beam-hosing instability is of key importance for the design of future plasma-wakefield accelerators. While previous work on this topic focused mainly on the blow-out wakefield regime, here we analyze theoretically the BBU for plasma-accelerators in the quasi-linear wakefield regime. Importantly, we show both analytically and numerically that, in this regime, the instability can saturate after a characteristic acceleration distance, due to head-to-tail variations in focusing forces. Thus the BBU in the quasi-linear regime may not as severe as standard scalings would suggest.
