Abstract
In order to excite the ions in the Lanzhou Penning Trap (LPT), two sets of RF phase splitters by using the principle of transformer have been developed, one of which is applied for the quadruple excitation and works at a frequency of 200 kHz 4 MHz and the other is for the dipole excitation and works at a frequency of 1700 ~1750 Hz. Their amplitude-frequency and phase-frequency characteristic curves in the condition of without-load and with-load have been tested in detail. The results showed that the amplitudes and the phases
of both RF phase splitters have met their design requirements.
