Wet chambers are used to maintain an environment for living and wet biological cells, so that they can be treated with X-rays for different purposes. For example, it is often important to hold living specimens for many hours in a vacuum and to be able to produce X-ray images of the living specimens. This cell is used to image wet and living cells onto a resist recording medium with X-rays, and for this purpose uses an optically transparent window of silicon nitride of sufficient thinness (100 A) to be transparent to X-rays. The wet chamber is shown in Fig. 1, while Fig. 2 shows an expanded view of the front window of the chamber which includes a "well" or grid pattern. In Fig. 1, the wet chamber includes a bottom portion 10, an intermediate portion 12, and the top portion 14.
