It is pure single bunch effect: dependent of bunch current but independent of total current. -1 mode signal has been seen in the bunch oscillation recorder at the emittance increase. The emittance increase depends on collimator aperture/impedance and bunch-by-bunch feedback system. We discuss the instability measurement and simulations to explain the phenomenon.}}, }
