We present a credible mechanism of spontaneous field emitter formation in high electric field applications, such as Compact Linear Collider in CERN (The European Organization for Nuclear Research). Discovery of such phenomena opens new pathway to tam

The reliability of HV insulation across a single gap, in vacuum and low-pressure gas, is known to be a critical issue to be addressed in the development and realization of the electrostatic accelerator for the ITER Neutral Beam Injector (NBI). This p

Dark currents studies with the Uppsala X-band Spectrometer at XBox test stand at CERN

Autor: Jacewicz, Marek

Vacuum arcs is the phenomenon which limits the performance of normal conducting accelerator cavities. It closely depends on electron field emission, which is consider a precursor for the creation of a vacuum discharge. These processes are still not f

Thermo-mechanical analysis of cryo-cooled electrode system in COMSOL

Autor: Olofsson, Joel

In the planned linear accelerator called Compact Linear Collider, CLIC, electrons and positrons will be accelerated to velocities near the speed of light. A limiting factor in accelerating structures are vacuum breakdowns, which are electrical discha
