Facility status reports

Oral presentation 20' + 5'

The TPS RF system consists of two RF plants. each at a power level of 300-kW, for the electron storage ring operation. The system performance and statistics on trip events in the recent years are presented. To improve the RF performance, some activities such as digital low level RF system and solid state amplifier are developed and implemented, whereas a spare 500-MHz superconducting RF...

3. Is it possible to simplify the RF system of a multi-port cavity? The case of the NEWGAIN RFQ.

New technology, new ideas, R&D, other technically interesting contributions

Oral presentation 20' + 5'

Multiport RFQ of several projects are powered by complex systems with several LLRF in master-slave configuration. No body seems promoting the architecture of parallel chains simply combined into the cavity, though this is commonly used in RF commercial amplifiers. The presentation aims at rising a discussion on the reasons of these complex architectures.

Oral presentation 20' + 5'

The Canadian Light Source (CLS) operates a single-cell CESR-B superconducting RF cavity system in the 2.9 GeV storage ring, powered by a 310 kW klystron.
In recent years CLS has been making changes to its RF systems with the aim to improve reliability. The booster klystron has been replaced with a solid state amplifier.
CLS has worked with ALBA to replace the LLRF system for
the booster....
