Information × Registration Number 0119U102423, ( 0220U010123  ) R & D request Title Study of Surface Layer Modification Effect in CLIC Accelerating Structures on Field Emission Current and High-Vacuum Breakdown Probability. Head Baturin Volodymyr A., Кандидат фізико-математичних наук Registration Date 08-07-2019 Organization Institute of Applied Physics, NAS of Ukraine popup.description1 Basing on ion-plasma coatings, the material modification techniques should be developed to produce the elements of accelerating structures (copper) in order to increase their resistance to vacuum high-voltage breakdowns. A filed emission should be developed with the effect of a metal surface modification on field emission density and maximum breakdown voltage considered. Experimental research should be performed to study the effect of such a modification on electron emission current and high voltage breakdown probability. Dependence between electron emission current and maximum breakdown voltage, and an interelectronic distance should be studied on the modified samples. The theory of field emission at high-vacuum breakdown with external magnetic field effect and relativistic effect considered should be developed. Joint and CERN coordinated research should be performed at test benches of IAP NAS of Ukraine and CERN. popup.nrat_date 2024-12-10 Close
