RF Noise Suppression for the APS Storage Ring
نویسندگان
چکیده
In a synchrotron, amplitude and phase noise in the radio-frequency (RF) system leads to timing jitter and energy fluctuations of the beam, which in turn cause orbital motion in dispersive regions. Electrical components in the RF system inevitably contain 60 Hz harmonic noise from the AC power grid. To suppress 60 Hz related noise, an adaptive notch filter was developed, implemented, and tested using a variety of digital signal processing techniques. Noise at targeted frequencies was reduced by ∼30 dB to ∼39 dB.

An Overview of the Aps 352-mhz Rf Systems
The Advanced Photon Source (APS) is a 7-GeV full energy positron storage ring for generating synchrotron radiation with an injector. The booster synchrotron rf system consists of a single 1-MW klystron which drives four five-cell cavities at 352 MHz. The storage ring cavities consist of four groups of four single cells powered by two 1-MW klystrons for 100-mA operation. An overview of the opera...
متن کاملAdvanced Photon Source Monopulse rf Beam Position Monitor Front-End Upgrade*
This paper will describe and analyze the rf beam position monitor (RFBPM) frontend upgrade for the Advanced Photon Source (APS) storage ring. This system is based on amplitude-to-phase (AM/PM) conversion monopulse receivers. The design and performance of the existing BPM front-end will be considered as the base-line design for the continuous effort to improve and upgrade the APS beam diagnostic...
متن کاملStorage Ring Isolation Valve
The RF impedance of the sector isolation valve of the APS storage ring system was measured by the wire method with a synthetic pulse technique [1]. The coupling impedance as well as the energy loss of the isolation valve with and without an RF liner or screen, and the flange gap of the various sizes was calculated from the measurements. There appear to be resonances at certain frequencies in th...
متن کاملStatus of Rf Deflecting Cavity Design for the Generation of Short X-ray Pulses in the Advanced Photon Source Storage Ring
The Advanced Photon Source (APS) at Argonne National Laboratory is exploring the possibility of using radio frequency deflection to generate x-ray radiation pulses on the order of 1 pico-second (Delta t – 70%) or less [1]. This scheme is based on a proposal by A. Zholents et al. [2] that relies on manipulating the transverse momentum of the electrons in a bunch by using an rf deflecting cavity ...
متن کاملHigh Accuracy Momentum Compaction Measurement for the APS Storage Ring with Undulator Radiation
We developed a new technique to measure the electron beam energy centroid and spread. It takes advantage of a sharp feature in the Advanced Photon Source (APS) diagnostic: undulator spectrum, the drop-off in the angle-integrated flux near its fundamental photon energy. The measurement technique has a high resolution and is nearly independent of the storage ring lattice functions. In this work, ...
