Status of the Rf System for the Anka Storage Ring

The RF system for the ANKA storage ring has two plants, each plant consists of one 250 kW transmitter at 500 MHz feeding two cavities, with all the peripherals. The different components, namely the high voltage power supply, the klystron, the waveguide system and the cavities, are now under construction and test. The HV power supply is provided by Jäger (Germany), and is been built on site. The...

Pep-ii Rf System Operation and Performance*

The Low Energy Ring (LER) and High Energy Ring (HER) RF systems have operated now on PEP-II since July 1998 and have assisted in breaking all design luminosity records back in June 2001. Luminosity on PEP-II has steadily increased since then as a consequence of larger e and e beam currents being accumulated. This has meant that the RF systems have inevitably been driven harder, not only to achi...

RF Noise Suppression for the APS Storage Ring

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 ...
