Abstract:
The DNA Phoenix program has investigated the power flow in the front end magnetically insulated transmission line MITL and PRS load assembly, to identify any losses, and model them, and the optimum injection angle and mass loading for a specific puff gas nozzle assembly. An optimum PRS mass loading can convert about 10-15 of the energy delivered to the front end into load kinetic energy over a range of 4.65 - 5.7 nH of initial PRS loading inductance. Specific kinetic energy per ion tends to fall off monotonically as the PRS length exceeds 4.5 cm. The gas puff optimization investigated nozzle designs which could optimize the uniformity of the implosion through high Mach number and tilting. The best yields for Argon were found at 12 deg for a Mach 4 nozzle, and 7.5 deg for a Mach 5 nozzle. The yield at the optimum tilt angle does not vary strongly with Mach number.
