Abstract

We report a simple, efficient, high voltage radio frequency (RF) generator powered by a single voltage source (1.5-7 V) to resonantly drive ion traps or other capacitive loads. Our circuit is able to deliver RF voltages > 500 V(p-p) at frequencies ranging from 0.1 to 10 MHz. This RF oscillator uses low-cost, commercially available components, and can be easily assembled onto a circuit board of a few cm(2). Because of its simplicity and good efficiency, this circuit is useful in applications requiring small size and low power consumption such as portable ion trap systems where the duration of operation under battery power is of concern.

摘要

我们报告了一种简单、高效的高压射频（RF）发生器，由单个电压源（1.5 - 7V）供电，用于谐振驱动离子阱或其他电容性负载。我们的电路能够在0.1至10MHz的频率范围内提供大于500V（峰 - 峰值）的射频电压。该射频振荡器使用低成本的商用组件，并且可以轻松组装到几平方厘米的电路板上。由于其简单性和良好的效率，该电路在需要小尺寸和低功耗的应用中很有用，例如便携式离子阱系统，在这种系统中，电池供电下的运行持续时间是需要考虑的因素。
