- Test Mass Discharging System (TMDS)
During operation of the ionizer, an unanticipated pressure drop such as might result from running out of purge gas, can cause the pressure in the vicinity of the corona needles to drop such that an uncontrolled and damaging arc can be induced. Great care must be taken to avoid such damaging arcs by keeping a close eye on the baratron pressure
