Abstract
Modern, general purpose high energy physics experiments are designed to rec ord the events of physics processes which greatly differ in rate. Both rare signatures with trigger rates of order 1 Hz and minimum bias interactions with rates sometimes approaching 1 MHz have to be triggered at the same tim e. The typical means of accommodating these requirements within a limited b andwidth is to downscale individual trigger channels appropriately. This pa per describes a novel procedure for finding an optimized set of downscale f actors that automatically adapts to the beam conditions. A first applicatio n at the H1 experiment at HERA showed that the number of events recorded fo r specific channels could be significantly increased.
