2. Ultrasound Cleaning
3. Ultrasound Rinsing
4. Centrifugal Barrel Tumbler
5. Ultrasound Rinsing
6. Electropolishing
7. Rinsing
8. Ultrasound Rinsing
9. Chemical Etching
10. Passivation
11. Ultrasound rinsing
12. Vacuum Cleaning
13. Careful vacuum packaging

ARIES is an Integrating Activity project which aims to develop European particle accelerator infrastructures, co-funded under the European Commission’s Horizon 2020 Research and Innovation programme.

TeFeNThick Films for New generation
resonant cavities
Research and development experiment in the three-year period 2019-2021.

The aim of TeFeN experiment is to demonstrate the possibility to realize Niobium on Copper resonant cavities with performances comparable to the bulk Niobium technology and not affected by Q-slope, an issue that for over 30 years has limited the application of this technology to low accelerating field.

On Nb thick film technology for resonant cavities, nowadays, the next step is to make this process stable and reproducible, increase the performances in terms of Q and Eacc at the same levels of Nb bulk cavities, and then scale it towards cavities of standard size for the accelerators, as for example 1.3 ot 1.5 GHz elliptical cavities. For the improvement of the performances is mandatory to define a correlation between process parameters and RF performances. Moreover, recent advances in the RF performances of the Niobium on Copper cavities, have highlighted the limiting effect of trapped magnetic flux, deeply studied in bulk Niobium cavities, but until now neglected in Niobium on Copper cavities.
During the three years of TeFeN experiment, LNL and Naples Section will study various aspects of Niobium on Copper superconducting films and will try to correlate them to the RF performances of the resonant cavities and the Q-slope phenomenon, starting from the results already achieved and the new studies carried out in the other international laboratories. Specifically, the TeFeN experiment will divided in three work packages, that investigate respectively:

  • WP1: development of the surface preparation of copper cavities.
  • WP2: Nb thick films coated via multilayer technique.
  • WP3: the effect of the residual magnetic field “trapped” in the superconducting film and its dependence on cooling.

DarkSide-50 at Gran Sasso underground laboratory (LNGS), Italy, is a direct dark matter search experiment based on a liquid argon TPC. DS-50 has completed its first dark matter run using atmospheric argon as target. The detector performances and the results of the first physics run are presented in this proceeding.

EASITrain – European Advanced Superconductivity Innovation and Training. 

The greatest challenges for wide-spread adoption of new applications of superconductivity remain the limited understanding of how to apply the fundamental principles on an engineering level and the capability to deploy the technology cost effectively on a large-scale.

EASITrain offers a cross-sectoral training program that is a fine blend of engineering, fundamental research and the development of real-scale applications in close collaboration with industry.

The EASITrain initiative aims to train the next generation of experts and establish a solid education curriculum to exploit the huge transformative potential of superconductivity.

Key research objectives include: Advance superconductor wire performance and production, develop industrial production methods, develop large-scale energy efficient cooling and deepen our understanding of the underlying mechanism of superconductivity.

EASITrain will assess the market potential of novel applications, aiming to contribute to the goals of energy efficiency and sustainable development. Possible applications include NMR, neuro-imaging, induction heaters and semiconductor crystal growth magnets, while there are numerous opportunities in emerging applications including superconducting fly-wheel energy storage, very high-temperature superconducting electronics, ship and aircraft propulsion systems, ultra-wideband and microwave sensing and communications.
