We study beam loading of electrons accelerated via the process of direct laser acceleration under the conditions of preformed plasma channels irradiated by ultra-intense laser pulses using analytical methods and particle-incell simulations in quasi-cylindrical geometry. We find the rates at which the electrons populate the beam for multi-petawatt peak power laser drivers. We show that the majority of accelerated electrons originate at the interface between the channel interior and channel wall and outline the underlying physical mechanism.
