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 3):
The method according to  claim 2  further comprising:\n generating an error signal by comparing the rectified signal to a stable set-point voltage reference.
