Scientific paper

The acceleration and collimation of particle beams in the funnel of thick accretion disks is investigated in the optically-thin-flow approximation. It is found that such flows can be collimated to within 0.1 radians by sufficiently thick disks. In addition, it is shown that the flow cannot convert more than a small fraction of the disk's (super-Eddington) luminosity into the energy flow of a narrow beam without being optically thick.
