Design and Simulation of the High-Sensitivity Tune Measurement System Based on Diode Detection at HIAF | |
|

| A high-sensitivity tune measurement system have been developed for the Booster Ring (BRing) and Spectrometer Ring (SRing) of the High-Intensity heavy-ion Accelerator Facility (HIAF). The beam signal induced by the BPM bipolar plate is amplified by the measurement system via a preamplifier, and then fed through the direct diode detection circuit to the spectrometer for Fourier analysis to calculate the tune fraction. Simulation results show a signal-to-noise ratio of approximately 50 dB without beam excitation. The new system is more sensitive to the detection of tuned fractions than conventional electronic storage ring tuning measurement systems and is simple and does not require beam excitation. This paper presents the design of HIAF tune measurement system, especially on front-end electronics design and the simulation results. | ||
