Dynamic Model for the Z Accelerator Vacuum Section Based on Transmission Line Code

【摘要】 <正> The transmission-line-circuit model of the Z accelerator,developed originally by W.A.STYGAR,P.A.CORCORAN,et al.,is revised.The revised model uses different calculationsfor the electron loss and flow impedance in the magnetically insulated transmission line systemof the Z accelerator before and after magnetic insulation is established.By including electronpressure and zero electric field at the cathode,a closed set of equations is obtained at each timestep,and dynamic shunt resistance (used to represent any electron loss to the anode) and flowimpedance are solved,which have been incorporated into the transmission line code for simulationsof the vacuum section in the Z accelerator.Finally,the results are discussed in comparison withearlier findings to show the effectiveness and limitations of the model.更多还原
