Sample Problem: Cylindrical Hohlraum at OMEGA

Overview

This example problem illustrates how to set up a problem with the following characteristics (it is for illustration purposes only):

• 10 OMEGA beams heat a cylindrical hohlraum. All beams enter one side.
• The hohlraum is oriented along the P6-P7 axis.
• The power in each beam is 0.5 TW, and has a 1 ns square pulse.
• The hohlraum has a length of 0.24 cm, LEH radius of 0.05 cm, and an initial radius of 0.08 cm.
• The radius decreases linearly with time, shrinking to 0.064 cm at 1.0 ns.
• A capsule with a radius of 0.025 cm is located at the center of the hohlraum.

After starting up VISRAD, the steps in this example application are:

• Set up the grid.
• View target to check alignment.
• Set the albedos and x-ray conversion efficiencies.
• Set up the laser beams.
• Set up simulation time grid.
• Run the simulation.
• View the results.
