Description	Journal: Journal of Physics: Conference Series Polar direct drive (PDD) makes it possible to perform direct-drive-ignition experiments at the National Ignition Facility while the facility is configured for x-ray drive. We present the first PDD ignition-relevant target designs to include the physical effects of crossbeam energy transfer (CBET) and nonlocal heat transport, both of which substantially affect the target drive. In the PDD configuration, a multiwavelength detuning strategy was found to be effective in mitigating the loss of coupling caused by CBET, allowing for implosion speeds comparable to those of previous designs. Two designs are described: a high-adiabat alpha-burning design and a lower-adiabat ignition design.
