| 摘 要： | 为了对兰州彭宁离子阱LPT内的离子运动进行偶极和四极共振激发,采用变压器原理,设计制作了两套分相器:一套工作频率为200 k Hz～4 MHz,适用于四极激发模式;另一套工作频率为1700～1750 Hz,适用于偶极激发模式。详细测试了它们在空载和负载情况下的幅频曲线与相频曲线。测试结果表明:RF分相偏置电路的输出幅度与相位均达到了设计要求。

| 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 phasesof both RF phase splitters have met their design requirements. |
