Beam dynamic phenomena described by bunch-by-bunch motion are important issues for a storage ring and are described by various theoretical formalisms. Direct measurements of the beam position related to different dynamical mechanisms are a useful inf

During the beam store test up to 400 mA in the storage ring, it was observed that the vacuum pressure around the RF window of the superconducting cavity rapidly increases over the interlock level limiting the availability of the maximum beam current

Three superconducting RF cavities were commissioned with electron beam in way of one by one during the last 3 years, and now PLS-II is in user service on the way of beam current to 400mA, the target of PLS-II. The cavities and cryomodules were prepar

The RF system of the Pohang Light Source-II (PLS-II) storage ring is operating at the 3.0 GeV/340 mA with three superconducting RF cavities. PLS-II RF system was upgraded to 3.0 GeV/400 mA (max.) beam storage from 2.5 GeV/ 200 mA of PLS. Each high po

The RF system for the Pohang Light Source (PLS) storage ring was greatly upgraded for PLS-II project of 400mA, 3.0GeV from 200mA, 2.5GeV. Three superconducting RF cavities with each 300kW maximum klystron amplifier were commissioned with electron bea

The design of RF amplifier of 100 kW (CW) at 165MHz is studied for a Radio Frequency Quadruple (RFQ). The RFQ as a linear accelerator is used for acceleration of low energy beam to 500 keV/u at KBSI [1]. An RF amplifier is composed of a drive, an int

The RF system for PLS-II upgrade, of which beam current and emittance are 400 mA and 5.6 nmrad at 3 GeV, becomes much more important compared to PLS. To reduce the HOM intensity in RF cavities for stable beam, a superconducting RF cavity is selected
