National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Spall Studies in Copper Foils Using the Laser-Driven Miniflyer.

DE2001764043

Publication Date	2000
Personal Author	Alexander, D. J.; Robbins, D. L.; Sheffield, S. A.
Page Count	11
Abstract	The Laser-Driven Miniflyer (LDMF) is a compact, laboratory-bench-top scale apparatus in which a laser pulse is used for producing high velocity impacts of small, planar flyers and targets. This device has been constructed at Los Alamos National Laboratory to conduct impact studies of small samples (1-3). The flyer plates are typically 3 mm in diameter, with a thickness of 50 m. The targets against which these flyers are impacted are generally about 10 mm by 10 mm 'in size, with thicknesses from 100 to 400 pm. Flyer velocities in excess of 1 kmls can be attained. target plate. This target assembly is then placed in a five-axis positioning holder, so that the center of the flyer can be precisely aligned on the optical axis of the laser.
