A vacuum accessory tool comprises a housing that defines a suction nozzle and an agitator assembly located in the suction nozzle and driven by an air turbine. A normalization component resamples an input trajectory to produce a resampled trajectory having a standard size. The apparatus further comprises an integrated circuit mounted adjacent the collimator, the IC subject to exposure to atomic particles, illustratively, neutrons. The system further includes a second scheduler operable to provide a minimum rate to each of the plurality of queues and a rate controller configured to modulate the rate of at least one of the first and second schedulers.
