The X-1 pulsed power facility would drive targets that could release very intense x-rays, debris ions and neutrons. These target emissions must be contained in an experiment chamber that allows access for a variety of high energy density experiments, while confining the radioactive vapors and rubble produced in each experiment. A study is in progress to design and analyze the experiment chamber for X-1. The vaporization of chamber materials by target emissions is considered and the mechanical loading on chamber structures by the rapid vaporization is predicted and discussed.
