    摘要： A method, and apparatus for accomplishing the method, for determining the frequency of an RF signal that operates by sequentially applying a received RF signal to sequentially selected individual filters having predetermined frequency pass bands and comparing the magnitudes of the filtered and unfiltered RF signals. The frequency of the RF signal is determined as being within the predetermined frequency pass band of a filter that outputs a largest magnitude output signal relative to the magnitude of the RF signal. Signals of insufficient magnitude are not processed by the system.

    摘要： An embodiment of the present invention includes the use of a single connection to measure the resonance frequency of main cells or side cells of a resonant structure, such as a linear accelerator cavity structure. Only one antenna is require to perform both the tasks of exciting a cavity structure and picking up the resonant frequency signal. According to an embodiment of the present invention, a first antenna probe is inserted into the main cells of a linear accelerator cavity structure. The first antenna probe includes an antenna window which may be positioned approximately in the center of a main cell adjacent to a target side cell in order to measure the resonance frequency of a target side cell. All non-target side cells adjacent to the main cell aligned with the window antenna are then shorted. For example, the non-target cells may be shorted by metal surrounding the first antenna probe at locations other than the antenna window. A signal is sent and a resonance frequency is noted. In order to measure the resonance frequency of a target main cell according to an embodiment of the present invention, a second antenna probe is inserted into a side cell adjacent to the target main cell. The main cells adjacent to the target main cell are then shorted and side cells adjacent to the target main cell are also shorted. A signal is sent and the resonance frequency of the target main cell is then measured.

    摘要翻译： 本发明的实施例包括使用单个连接来测量诸如线性加速器腔结构的谐振结构的主单元或侧单元的谐振频率。 只需要一个天线来执行激发腔结构和拾取谐振频率信号的任务。 根据本发明的实施例，将第一天线探针插入到线性加速器腔结构的主单元中。 第一天线探针包括天线窗口，其可以位于与目标侧单元相邻的主单元的大致中心附近，以便测量目标侧单元的谐振频率。 然后与窗口天线对准的与主单元相邻的所有非目标侧单元被短路。 例如，在非天线窗口之外的位置处，非目标单元可能被围绕第一天线探针的金属短路。 发送信号并记录共振频率。 为了测量根据本发明的实施例的目标主单元的谐振频率，第二天线探针插入到与目标主单元相邻的侧单元中。 然后与目标主电池相邻的主电池短路，与主电池相邻的侧电池也短路。 发送信号，然后测量目标主单元的谐振频率。
