摘要
RF circuit board has a significant impact on performance of the Digital Beam Position Monitor (DBPM) in storage ring of a synchrotron radiation facility.In this paper,a front-end RF board is designed for DBPM,and schematics of the RF board and the test results are given.In view of the inevitable inconsistency in the multi-channel circuit,a calibration circuit is designed to reduce such an influence.The test results show that the calibration method is useful for beam current dependence which is sensitive to channels inconsistency.
RF circuit board has a significant impact on performance of the Digital Beam Position Monitor （DBPM） in storage ring of a synchrotron radiation facility. In this paper, a front-end RF board is designed for DBPM, and schematics of the RF board and the test results are given. In view of the inevitable inconsistency in the multi-channel circuit, a calibration circuit is designed to reduce such an influence. The test results show that the calibration method is useful for beam current dependence which is sensitive to channels inconsistency.
