Abstract
The fabrication of high-quality ultra thin (~20 micron) diamond crystals targets for 9 GeV highly polarized photon beams is an outstanding challenge. Current state of the art polishing/thinning techniques are not successful in thinning single crystal diamond to such dimension because of its extreme hardness and chemical inertness. These techniques create significant stresses surface and sub-surface damage that limits the final thickness to approximately 100
