The heat transfer characteristics of feedthrough flange under high alternating current excitation were investigated by threedimensional finite element *** correlations between the heat transfer behaviors and system parameters including applied current,ceramic thickness and working time were discussed comprehensively.A remarkable absorbed power beyond 100 W in flange would be produced by the electromagnetic field from *** natural cooling condition,there is an obvious temperature rise about 40℃in the flange center after 10 min of current *** types of water cooling solutions acting on flange surface,*** type,circle type and S type solutions,were proposed to reduce the flange temperature under high alternating current and long working time *** the S type water cooling mode,the best cooling effect can be achieved that the maximum temperature rise is about 20℃and the average temperature rise is less than 5℃.

Purpose The superfast kickers are required for the HEPS storage ring on-axis injection system due to its very small dynamic aperture.A 750-mm-long stripline pair type of kicker prototype was researched and developed to demonstrate achieved performance of bandwidth,impedance,kicker strength,field uniformity and beam power *** The cross sections of the kicker main body and the end of taper part are optimized for a good impedance matching and field uniformity.3D simulation further optimizes the taper part to minimize the beam power loss and maintain a lower *** high-voltage feedthrough is also designed and optimized by 3D *** and high-voltage measurements are taken to verify the design of kicker *** The testing transmission odd-mode impedance is 50±0.5Ω,the even-mode impedance is 60±0.5Ω,and return loss is less than−13 *** peak voltage and the rise time of pulse width inserting kicker assembly just decrease 3%of 20 kV and slow down 80 ps,*** RF testing results agree well with the simulation ones,which meet the design *** kicker assembly works well at±20 kV pulse.
