Solid- or dry-wall chambers are expected to be compatible with laser-beam or ion-beam entrance into the chamber. If the dry wall chamber is evacuated or has a gas fill of no more than a few tens of millitorrs (at room temperature), then it may be possible to have easier target injection, target tracking, target survival, high-fidelity laser propagation, restoration of chamber conditions for the next shot, and gas reprocessing (e.g., cooling and target debris removal).

Dry-wall chambers, which have no constraints for liquid film or liquid jet geometry, should be able to accommodate the illumination geometry for either direct-drive or indirect-drive targets. For laser drivers, chamber designs have been proposed to deal with target emission from either direct-drive (e.g., HAPL30) or indirect-drive (e.g., LIFE31) targets. An example is shown on Figure 3.8.

Wetted-wall chambers could be compatible with either direct-drive or indirect-drive illumination, but there are some advantages to indirect drive since it would be possible to configure the beam paths from the sides and this could reduce the chance of liquid reaching the final optics. The thin liquid layer would be able to withstand short-range ion, X-ray, and debris emissions from either direct-drive or indirect-drive targets.
