Decade quad monolithic POS modeling

The decade quad (DQ) was initially fielded as a large area bremsstrahlung (LAB) source. This utilized the four decade modules (DM) triggered simultaneously but each driving a separate hard X-ray bremsstrahlung radiation source (BRS). Recently, water convolute hardware was installed that combines the power from the four Decade modules to drive a soft X-ray plasma radiation source (PRS). The water convolute configuration also enables the use of a monolithic plasma opening switch (MPOS) for driving a common BRS or PRS load. The work reported here was performed in support of the use of an ACE 4 type POS on DQ. The modeling included equivalent circuit and DELTA-CREMIT magneto-hydrodynamic (MHD) simulations. The circuit analysis extracted equivalent circuit parameters from ACE 4 data and applied them to the planned DQ MPOS-BRS configuration. The MHD analyses evaluated strategies to optimize the DQ MPOS.
