Examples of preheatpreheat By design, the direct-drive target is essentially preheat-free. They also found that the observed expansion rates for preheated wires were essentially identical to wires that were not preheated. X-ray preheating leads to the expansion of the target rear surfaces. We see that preheat on both surfaces increases with increasing intensity. Such electrons can preheat the fuel in laser fusion applications. This may lead to preheating of the target. X-rays are generated which cannot preheat the material in depth. The left graph is the control target, the right the radiation preheated target. In principle, we do expect that preheating effects to vanish going to sufficiently low laser intensities. This may result in no visible reduction of preheating effects when laser intensity is decreased. The beam currents that are required for the discharge initiation are easily produced and do not preheat the fusion target. Without preheating the jet would reach much higher velocity, as the jet is not stopped by the surrounding plasma. Simulation of preheating effects in shock wave experiments. At those energies, opacities are low and photons can propagate inward and preheat the base, reference and test materials steps. These subsequent tests also found no measurable difference in any diagnostics between wires preheated for 30 minutes and wires preheated for 8-12 hours.
