摘要： An apparatus and method for enhancing pulse contrast ratios for drive lasers and electron accelerators. The invention comprises a mechanical dual-shutter system wherein the shutters are placed sequentially in series in a laser beam path. Each shutter of the dual shutter system has an individually operated trigger for opening and closing the shutter. As the triggers are operated individually, the delay between opening and closing first shutter and opening and closing the second shutter is variable providing for variable differential time windows and enhancement of pulse contrast ratio.

摘要： A support for suspending reinforcing steel relative to a form wall at a spaced distance is provided. The support includes a vertical member having a first end and a second end, a cantilever support arm extending from the vertical member for supporting a length of reinforcing steel orientated horizontally at a predetermined elevation and at a spaced distance from the form wall, and a clamp means for securing the support to the form wall so that the support arm is perpendicular to the form wall and extends towards the opposite side of the form. A plurality of support arms can be provided for suspending many different lengths of reinforcing steel at different elevations. The support is intended to be used in the construction of reinforcing structures, as for grade beams and is removed from the form wall prior to the pouring of concrete into the form.
