RITS-6 Output Pulse Modifications

Summary form only given. The RITS accelerator was upgraded from three pulse forming lines (PFL) and inductive voltage adder (IVA) cells to six PFLs and IVA cells during 2005 with radiographic diode experiments beginning in 2006. Flexibility in the accelerator architecture via changes in the magnetically-insulated transmission line (MITL) allows us to efficiently drive a variety of diodes with varying impedances. The original RS-6 accelerator configuration is capable of operation at voltages greater than 10 MV with an 80-Omega MITL. Low impedance diodes such as the self-magnetic pinch (SMP) diode are not matched well to the high impedance MITL and decrease the diode voltage to about 5 MV. A low impedance MITL has been designed and tested with an operating impedance of about 40 at the output end, Large area diode experiments with both MITL impedances are presented.
