To ensure that this can happen, it is vital for those who design, manage or use electro-medical devices to consider electromagnetic compatibility (EMC). In a hospital, the electromagnetic environment can be quite harsh, ...

A. ELECTRON DENSITY MEASUREMENTS IN CONTINUOUS ARGON ION LASERS We are continuing our studies of the electron density in argon ion laser discharges. Several improvements have been made in our diagnostic equipment since our last report. l We present some preliminary results of measurements performed on continuous argon discharges. 1. Steady-State Discharge Measurements Figure VII-1 is a block di...
