A simplified model describing the PWFA transverse instability in the form of a wake function parameterized only with an effective cavity aperture radius $a$ is benchmarked against QuickPIC simulations. This wake function implies a $1/a^4$ scaling of the transverse wakefields, which indicates transverse intra-beam wakefields typically several orders of magnitude higher than in conventional acceleration structures. The constraint on main beam charge and effiency imposed by such transverse wakefields is addressed using a simplified theoretical model and numerical simulations, and a mitigation method inspired by BNS damping is also assessed.
