5.1 Introduction

The quadrupolar configuration (four-pole arrangement) is widely used in several engineering and physical systems and well understood in the electrical, magnetic, acoustic, and gravitational fields. Most famous and practical applications of quadrupoles are the use of quadrupolar magnets to focus beams of charged particles in particle accelerators [1] and the use of quadrupolar electrical fields in mass spectrometers to filter ions based ...
