Abstract: The present invention relates to UV protective fabrics, whereupon these fabrics are made of UV protective cellulosic fibers, namely manufactured by the Modal or the Lyocell process. Besides the permanent and inherent protection against UV rays of the named fiber materials and thus fabrics, UV protection is still guaranteed, when the fabrics are wet and stretched. As a result of fiber swelling, the fabric construction becomes denser and as a direct result, UV transmission is significantly reduced compared to the dry and stretched state.

Abstract: An implanter provides two-dimensional scanning of a substrate relative to an implant beam so that the beam draws a raster of scan lines on the substrate. The beam current is measured at turnaround points off the substrate and the current value is used to control the subsequent fast scan speed so as to compensate for the effect of any variation in beam current on dose uniformity in the slow scan direction. The scanning may produce a raster of non-intersecting uniformly spaced parallel scan lines and the spacing between the lines is selected to ensure appropriate dose uniformity.
