What is the key question that you try to address?

The key questions that my research aims to address is whether the same Niobium superconducting properties can be reproduced by using thick film deposition on SRF cavities. This alternative method will allow to significantly reducing costs for future accelerators used for particle physics but also in industry.

Is it possible to reduce the cost of high energy physics research or perhaps more broadly can we use the properties of one expensive material in a cheaper way?

 

 

 
Which are the tools that you are using?

We are using Niobium coating on copper structures. This coating is made by Physical vapour deposition technique (magnetron sputtering).

 

 

 
Could you briefly mention the latest results of your research?

Superconducting radiofrequency cavities are the elements that actually accelerate the particles in the particles accelerators such as LHC at CERN. In order to reduce the cost of future accelerators, instead of using a bulk material, we use a coating of the material in order to reproduce its properties but reducing costs. Our latest results showed that is possible to obtained coated Niobium on Copper cavities performances comparable with the standard Niobium cavities, just by depositing a thick film of tens of microns. This thick film is made by depositing thin films of 500 nanometers until the thick film is achieved. This multiples coatings permits the films to have a good adhesion without any stress in the material. By characterization of film microstructure is possible to observe a uniform and columnar grain growth that permits performances of these cavities comparable to the Nb bulk standard cavities used nowadays in accelerators all over the world

 

 

 
Which are the next steps?

Improve the reproducibility of the results by improving the surface treatments and the deposition parameters. Also, to understand how to continue improving the performances of the cavities by studying their microstructure.

 

 

 

 
Could you research have some applications?

The coating applications is widespread. From decoration, to hard coating in tools, to superconducting applications, to reflective surfaces applications and to medicine. Nowadays coating techniques are well known in the industry for different purposes.
