Microprocessor based data acquisition and control system for a balloon borne quadrupole mass spectrometer

A microprocessor based data acquisition and control system has been designed and constructed for use in balloon borne quadrupole mass spectrometers. It combines the capabilities of an ion counter/discriminator, a spectrum accumulator, an intelligent mass scan controller, a multiplexed ana¬ log to digital converter, a relay controller, a PCM encoder for serial digital output, multiple analog outputs and an interface to remote control signals. The system has been flown successfully in the stratosphere.Nevejans D., Frederick P., Arijs Etienne.
