There is included a laser producing a beam for irradiating the irradiation targets to generate an EUV-producing plasma, wherein the electro-actuable element is biased against the nozzle to enable transfer of the disturbance to the droplets while permitting relative movement between the electro-actuable element and the nozzle.

  • Publication number: 20140262020
    Abstract: Primer compositions for adhering two sheets of polymer material to one another are provided. The primer compositions include polyurethanes that are the reaction product of an isocyanate, and at least one of a polyol, a chain extender, and a diamine. The polyurethanes may include pure polyurethanes, or commercially available varieties that may include other additives. The premier compositions are well-suited for adhering polycarbonate and polyurethane sheets together for use in transparent armor applications, as they help to ensure a very strong bond between the two sheets, and resist delamination.
