Abstract
The invention relates to ion-optical RF-operated electrode systems such as ion guide systems, ion fragmentation systems, ion filtering systems or ion storage systems which require additional DC potential gradients by means of DC voltages on resistance systems. The invention consists in supplying the DC voltages via center taps between several separate secondary windings of an RF transformer generating the RF voltage.
