Abstract：In this paper, the basic structure of MLCi2 multi-leaf collimator for Elekta linear accelerator was introduced, and the
principle of optical structure control was analyzed in detail. Importantly, optical optimization, blade driving current test, tungsten gate
potentiometer drawing test and camera life judgment mentioned in this paper were all effective solutions in daily maintenance. Taking
three more classic fault inspections and repairs as an example, this paper provides lessons for the maintenance of similar multi-leaf
collimators.
