The geometrical efficiency is calculated for a radioactive source-moderator assembly, which is often used for the production of slow-positron beams, and comparisons are made between a cylinder source, touching the circumference of the moderator, and a spot source, facing the center of the moderator. It is shown that higher beam intensity and brightness can be obtained with the cylinder source in most practical situations.
