<p>An imaging chamber for an electron radiography system, including spaced spherical electrodes defining a gas gap therebetween. An arrangement for clamping the receptor sheet and stretching it to a spherical configuration against one of the electrodes. A plurality of clamp strips disposed about one electrode and spring loaded toward the other electrode, with the other electrode being moveable toward the first electrode to clamp the receptor sheet at the clamp strips and then move the clamp strips against the spring load to stretch the clamped receptor sheet.</p> |
