Abstract: An important issue for the refurbishment ofthe Z accelerator at Sandia National Laboratories [I] is limiting electron losses to the anode in the vacuum section. As on Z, the ZR vacuum section consists of four magnetically insulated transmission lines (MITLs) coupled in parallel, with a double-post-hole convolute, into the final MITL delivering the full current to the load. On Z, there is clear evidence of 5-10% current losses late in the power pulse, in the convolure. 3-D particle-incell (PIC) simulations [2…
