Novel components reduce background noise caused by secondary ions generated by metastable entity bombardment in a mass spectrometric system. Layered structures for exit electrodes and deflector plates confine secondary ions in a local low-energy well, preventing them from entering the detector.
L'invention porte sur de nouveaux composants qui réduisent un bruit de fond provoqué par des ions secondaires générés par un bombardement d'entité métastable dans un système de spectrométrie de masse. Des structures en couches pour des électrodes de sortie et des plaques de déviation confinent des ions secondaires dans un puits local à faible énergie, les empêchant d'entrer dans le capteur.
