Strategies to Prevent Debris Deposition in the Beam Tubes (I)
• Design efficient target chamber structures
• Mass and energy fluxes at the entrance of beam ports should be as low as possible
• Venting in target chamber has been modeled to determine inlet boundary conditions for the beam tubes

The TSUNAMI 2.8.1 Code
•TranSient Upwind Numerical Analysis Method for Inertial confinement fusion
• Provides estimates of the gas dynamics behavior during the venting process in inertial confinement energy systems
• Ideal gas equation (gives conservative results)
• Solves Euler’s equations for compressible flows
• Two-dimensional, axially symmetric pocket
