Dynamic control and annulment of electromagnetic pollution

Octavian Baltag, Doina Costandache

Abstract

A method and an installation for annulling the parasite alternative magnetic induction in the laboratory is presented. The installation controls the magnetic field level inside the volume where a MAT 252 mass spectrometer is situated. The field control is achieved by means of a system of a large Helmholtz coil having the spectrometer placed in their centre. A field transducer permanently measures the induction level and delivers a correction signal that monitors the compensation current intensity through the Helmholtz coil. The installation is meant to work in the laboratories situated in places where the industrial EM pollution can not be suppressed by other methods.
