Superconducting Accelerating RF-Structure Stability at a High Energy Level from the Point of View of Thermal Balance.
Protvino, 2000.-p.9, figs.7, tables 2, refs.:17.


Theoretical calculational results for critical magnetic fields and phase diagram for superconducting Niobium (NBR), type specially developed by GIREDMET company to manufacture accelerating cavities, are submitted. The dependence of temperature overfall at the internal and external bounderies of the cavity on dissipated RF- power is given. The calculation of a temperature pressure and graphical representation of the thermal balance equation enables one to consider the behaviour of the accelerating SVAAP cavity (from pure Niobium) at RF- power.
