INFN MILANO - LASA ACTIVITIES FOR ESS

INFN Milano - LASA is involved in the development and industrialization for the production of 704.4 MHz medium beta (E = 0.67) cavities for the ESS project. In this framework, we are designing a medium beta prototype cavity exploring both Large Grain and Fine Grain Niobium for its production as well as a high beta (E = 0.86) Large Grain cavity. In the meanwhile, an activity is ongoing for upgrading the LASA test facility to be able to test these kind of resonators.
