Abstract:

The use of lithium hydride LiH for both return current structures and initial debris shielding is explored and a general set of design criteria is derived. It is found that, particularly when the testing requirement is for argon K shell radiation, LiH shields can improve the expected fluence on a test object over present or recently proposed technologies. The concept rests upon a tradeoff between the proximity of a test object to the plasma radiation source PRS and the opacity of any shielding that is interposed. Because a larger mass of intervening shield material is possible with LiH, the expected debris velocities are 100 times or more slow than current measurements. A cold press technique for the fabrication of the shield and its electrical connection to a pulser is specified.
