CAS visits Helmholtz-Zentrum Berlin during its RF school

Each CAS school, except for the basic one, is located in a different member state of CERN. This allows participants to learn about the science and culture of the host country, as well as work with local labs during the school's organisation and planning.

One of the most exciting activities during the school is the opportunity to visit one laboratory in there.

It's essential to facilitate exchange between the participants and the host country. Collaboration and teamwork can lead to beautiful achievements and success.?

During the specialised course on RF for accelerators, our local organiser in Berlin, Helmholtz-Zentrum Berlin organised an incredible visit focused on Radio Frequency (RF).

Students were shown the SRF (Superconducting Radio-Frequency) infrastructure during the tours through five themed stations.

Each group of 10 students had a "station expert" from HZB to explain the scene. The "HoBiCaT" lab demonstrated how superconducting dressed and bare cavities can be RF tested at 2 degrees above absolute zero.

The new Testing Hall showcased the three booster SRF cavities for SEALab (Superconducting Electron Accelerator Lab), one of which was already equipped with a mechanical tuner, and the fundamental power coupler conditioning stand. The students then visited the LLRF lab to see the state-of-the-art mTCA. 4 pieces of equipment for HZB's low-level RF control projects and a new system based on an RFSoC development board.

The SEALab Energy Recovery Linac facility was a highlight of the tour, where the students inspected the accelerator facility with auxiliary equipment such as the new Solid State Amplifiers and Klystrons, and the assembly of the future accelerator SRF photo injector module.

Finally, a sixth station provided cold drinks and cookies while posters on the HZB research could be viewed.

We are preparing the following courses with our local organisers and have inspiring visits planned. If you are curious about our next courses and destinations, check our website https://cas.web.cern.ch
