This device is composed of two stretched mylar sheets with each sheet attached to one half of the mount. The diamond will be placed between the sheets.  This advantage of this type of mount is that it will create very little stress on the diamond sample, preventing the sample from warping.  This type of mount cannot be used in the final beam path at JLab because the high temperatures in the vacuum chamber (~500<sup>o</sup>C) will deform the mylar sheets.

In order to use this mount in the diamond analysis, the center area of the mylar must be sufficiently flat.  To ensure this flatness, a large sheet of mylar (100 <math> \mu m</math>, most likely 24" x 24") will be placed over and attached to a drum with an 18" diameter.  The large diameter will ensure that any small wrinkles at the edges will not propagate all the way to the center region.  The mount will then be glued to the mylar and while the glue is still tacky, the mylar will be stretched. The mylar will be stretched by placing a weighted container (approximately 100 pounds) on top of it.  The following calculations

The mylar will be stretched by placing a weighted container (approximately 100 pounds) on top of it. To verify that the center region is flat, the mount will be placed in the interferometer, and the interferogram will be analyzed using the process found [http://zeus.phys.uconn.edu/wiki/index.php/Analysis_of_Michelson_interference_images here]This will give us an image of the surface of the mylar.
