The first high energy 4th generation low emittance ring, the Extremely Brilliant Source EBS, is in user operation since August 2020. The existing SSA and klystron transmitters where kept to power the 13 new mono-cell HOM damped EBS cavities. Ten new 110 kW SSAs have recently been ordered from JEMA-France to replace the more than 30 years old klystron transmitters until end 2026 and the site...

On 30th of September, “dark-time” started for the SLS 2.0 upgrade. Unfortunately, the machine availability of the last year was one of the worst since start of SLS operation. Several outages were caused by water-leaks and by the cryo-system of the Super-3HC.

Dr Lu zhao (Synchrotron SOLEIL)11/8/23, 11:00 AM26th ESLS RF Workshop
SOLEIL II is currently advancing through the conceptual design phase. Within the realm of radio frequency (RF) activities, our focus has been on enhancing the High-Power RF Solid-State Amplifier, aiming to boost reliability and minimize energy consumption. To achieve this, we've successfully fabricated and tested a prototype of the amplifier at SOLEIL/Booster. In addition, we've developed and...

In addition to extensive infrastructure construction activities, the RF systems will also be rebuilt in a new RF building.
The booster (DESY II) will as well be rebuilt in the old DESY synchrotron tunnel.
This means that we will say goodbye to klystrons and the majority of multicell cavities and switch... -

Pol Solans (ALBA Synchrotron)11/8/23, 12:00 PM26th ESLS RF Workshop
ALBA is a 3rd generation synchrotron light source located in Barcelona, Spain and in operation since 2012. The storage ring RF system consists of six HOM-damped normal conducting cavities, fed with IOT based transmitters able to deliver up to 160 kW each. The booster counts with one 5-cell PETRA type cavity fed with a SSPA delivering up to 50 kW. This presentation aims to summarize the...

A simulator of longitudinal dynamics based on an analytical frequency domain model was developed to evaluate the transient beam loading in the Elettra 2.0 storage ring. Experiments have been carried out in the present Elettra machine to characterize the harmonic cavity and to compare the simulator with the real machine.

FLUTE (Ferninfrarot Linac- Und Test-Experiment) at KIT, developed and operated by KIT-IBPT, serves as an accelerator test facility for a variety of accelerator studies, delivering coherent radiation in the form of ultra-short, very intense light pulses spanning the terahertz and far-infrared spectral range and beyond. It will also serve as an injector for a compact Very Large Acceptance...

An overview and a status of the RF systems used at the ASTRID2 facility will be presented, including the new 3 GHz RF system for our Microtron. The talk will also include a report on our on-going efforts on improving the ASTRID2 beam stability and lifetime by optimizing the 3rd harmonic Landau cavity temperature and detuning.

FERMI is the seeded free electron laser (FEL) user facility at Elettra laboratory in Trieste, operating in the VUV to soft X-rays spectral range. In order to extend the FEL spectral range to shorter wavelengths, an increase in the linear accelerator (linac) energy from 1.5 GeV to 2.0 GeV is required. This result will be achieved by replacing the present old sections with the newly designed...

Dr Peter Hülsmann (DESY)11/9/23, 9:40 AM26th ESLS RF Workshop
PETRA IV will use the BESSY HOM damped cavities for the fundamental 500 MHz RF system. In order to reduce the negative effects of Touschek and intrabeam scattering on the lifetime and emittance of the electron bunches, third harmonic cavities will be installed. They elongate the bunches and thus reduce their charge density. One possible candidate for a third harmonic cavity is the 1.5 GHz ALBA...

Henrique O. Caiafa Duarte (MAX IV Laboratory)11/9/23, 10:50 AM26th ESLS RF Workshop
This presentation describes the electromagnetic, thermal and mechanical design and RF characterization for the prototype HOM dampers for the MAX IV 100 MHz RF cavities. The dampers are of antenna type and aim to reduce the shunt impedance of all modes to below ~3 kOhms while keeping one of the modes basically unaffected in both frequency and quality factor so that it can be effectively dealt...
