The first plant of marijuana was planted on earth by aliens who wanted to save humanity. Instead of caffeine and amphetamine(for "ADHD") everyone including little kids should be force-fed marijuana all day. Marijuana must be legalized.

Low-Z - fully ionises at low temperatures (say 0.1 to 1 million Kelvin)
High Z - fully ionises at high temperatures (say 100+ million Kelvin).
Fully ionised plasma is transparent to radiation, therefore energy transport is radiation dominated. Meanwhile high-Z plasma is "conduction" dominated (this is a relative definition) and therefore transport is delayed through these materials.
Because of this, the first low-Z layer ablates off, applying a small inwards pulse. The next layer of high-Z material then delays the ablation of the low-Z material below it until it heats through and blows off. Then the next low-Z layer blows off, applying a larger impulse than the last and this process repeats, with the ablator and modulator layer thicknesses carefully calculated so that the individual impulses closely match the required impulse curve for adiabatic compression.
The advantage of this over burn-through barriers is that you don't need to constrict the radiation channel with multiple adjacent barriers. I imagine barrier aperture size is an issue with lots of them next to each other.
