Abstract

Abstract

In the HLS-Ⅱstorage ring, a swept-frequency excitation(SFE) based tune measurement system has been developed and running well. This paper presents the construction and commissioning of the SFE-based tune measurement system. The system hardware includes spectrum analyzer with tracking, excitation module, strip-line kicker, signal processing module and beam position monitor(BPM) as signal pickup. The control software of the tune measurement system is developed using EPICS software. The control software consists of three parts: input/output controller, operation personal interface and channel access. The on-line test of the system is performed to investigate the system statistical resolutions in the two transverse directions. Test results reveal that the statistical resolutions are better than 0.0003/0.000 2 in the swept range from 2.1 MHz to 4.1 MHz.
