Abstract:
Disclosed are improved methods and structures for actively stabilizing the oscillation frequency of a trapped ion by noninvasively sampling and rectifying the high voltage RF potential at circuit locations between a step-up transformer and a vacuum feedthrough leading to the ion trap electrodes. We use this sampled/rectified signal in a feedback loop to regulate the RF input amplitude to the circuit. By employing techniques and structures according to the present disclosure we are advantageously able to stabilize a 1 MHz trapped ion oscillation frequency to <10 Hz after 200 s of integration, representing a 34 dB reduction in the level of trap frequency noise and drift, over a locking bandwidth of up to 30 kHz.

Claim (Index 9):
A system for actively stabilizing ion trap radiofrequency (RF) potentials comprising:\n means for noninvasively sampling a high voltage potential at a position in a circuit between a step-up transformer and a vacuum feedthrough for electrodes of the ion trap; means for rectifying the sampled high voltage potential signal; and means for applying the rectified signal to a feedback loop of the circuit such that an amplitude of an RF input to the circuit is desirably regulated, and the ion trap RF potentials are actively stabilized; wherein the rectifying means further includes temperature compensating means including two matched diodes configured for passive temperature compensation in conjunction with a low-pass filter configured such that a ripple amplitude of at least 10 dB below diode input signal amplitude is produced.
