    Abstract: A process that provides the ability to incorporate a self exciting loop (SEL) algorithm into a digital LLRF system. The present digital SEL provides for conversion from the Cartesian domain to the Polar domain, wherein most signal processing is accomplished, and back to Cartesian. By handling most signal processing in the Polar (phase & amplitude) domain, a perfect amplitude limiter can be realized and simpler logic operations can be used. When operational, cavity recovery from faults will be tuner-less. At high gradients, ˜20 MV/m, like those needed for the upgraded cryomodules, the Lorentz detuning will be many bandwidths, making cavity turn-on problematic with out some tuner based compensation or other algorithmic solution. The present SEL solves this problem and allows cavity recovery from cryogenic trips, wherein cavities have been known to detune 1000's of Hz. Other applications such has He processing can also be implemented in situ without additional electronics.

    Abstract translation: 提供将自激循环（SEL）算法结合到数字LLRF系统中的能力的过程。 本数字SEL提供从笛卡尔域到极域的转换，其中大多数信号处理完成并且返回到笛卡尔坐标。 通过处理极地（相位和幅度）域中的大多数信号处理，可以实现完美的幅度限制器，并且可以使用更简单的逻辑运算。 在运行时，故障的腔恢复将无调谐器。 在高梯度，〜20 MV / m，像升级的低温模块所需要的那样，洛伦兹失谐会带来许多带宽，使得一些基于调谐器的补偿或其他算法解决方案导致空腔开启问题。 本SEL解决了这个问题，并允许空穴从低温跳闸恢复，其中已知空腔使1000的Hz失谐。 He处理的其他应用也可以在原地实现，无需附加电子设备。

    Abstract: An apparatus and method are disclosed for improving the stability of the frequency of vibration of an oscillator signal produced by an oscillator circuit. In a preferred embodiment of the present invention, a quartz crystal resonator is one arm of a bridge which generates a bridge signal which varies in accordance with the vibrating frequency of the resonator. A synchronous demodulator responds to the bridge signal for producing an error signal. A control circuit receives the error signal and changes its reactance when the resonator is no longer vibrating at its unperturbed resonance frequency so that the vibration frequency of the resonator connected to the control circuit is returned to its resonant frequency. An automatic level control circuit is also included for controlling the drive level of the signal exciting the resonator.
