Abstract
An electromagnet assembly suitable for mass spectrometer comprising one yoke; and two pole pieces; the pole pieces being comprised in a vacuum chamber and being separated from each other by a pole piece gap defining a passage for the charged particles to be deflected; the yoke forming a bridge over the two pole pieces thus defining a magnetic circuit. The electromagnet assembly further comprises one electrical circuit for generating a magnetic flux in the magnetic circuit, the electrical circuit being included in the yoke. The electromagnet assembly is remarkable in that the pole pieces are electrically insulated from the electrical circuit and from the yoke by first electrical insulating means and are electrically insulated from the vacuum chamber.
