As the address of EEPROM, which was used for looking2up table, the information of octant and signals of magnetic encoder which were converted by A /D converterwere dealt by FPGA. And the frequencymultip lication formagnetic encoderwas comp leted. So the resolution and accuracy ofmagnetic encoderwere imp roved, 4096 multip le frequencies can be achieved in per cycle.

同时利用FPGA对卦限信息和磁编码器输出信号的A /D转换信息进行处理，作为EEPROM的地址信息进行硬件查表，实现对磁编码器信号的倍频处理，从而提高了磁编码器的分辨率和测量精度，可实现每个周期4 096份的倍频。

To verify this method, a 0.915/2.45 GHz dual band rat-race hybrid and a 0.915/2.58 GHz branch-line coupler were designed, fabricated, and measured.

此方法运用於双频段鼠圈式功率分配器和分枝线耦合器(Branch-line)，第一频段设计在0.915 GHz，并将原三倍频点移至2.45和2.58 GHz，形成双频特性。

The electron beam current measured by the beam current monitor (BCT3) is almost in direct proportion to the induced voltage of the fundamental harmonic. When the parameters of the pre-buncher and buncher are adjusted greatly while the beam current being unchanged, the fifth harmonic signal has a great change, but the fundamental signal changes gently. The test results are all in good agreement with the theoretic analysis.

根据不同时刻的记录，基频腔峰值电压与束流流强探测器BCT3所测流强值近似成正比关系；当大幅改变预聚束器和聚束器参数而束流流强不变时，反映聚束质量的五倍频腔信号也随之大幅改变，而反映流强信号的基频腔信号则变化不大，这些试验结果与理论分析完全一致。

The measured bunch length ranging between 1.4 mm and 2.0 mm agrees well with the theoretic calculation of 1.5 mm.The electron beam current measured by the beam current monitor(BCT3) is almost in direct proportion to the induced voltage of the fundamental harmonic.When the parameters of the pre-buncher and buncher are adjusted greatly while the beam current ...
