Abstract:

The OWL 2 generator, in conjunction with the large area beam hardware, generated a reproducible uniform electron beam capable of removing between 0.013 and 0.025 cm depth of phenolic from carbon phenolic ablator surfaces. The beam had a diameter of 19 cm 280 sq cm. Specimens of staple rayon and continuous filament rayon carbon phenolic were irradiated. Samples included both flat and conical section configurations. Stress pulse measurements were performed on each type of material using quartz gages. The irradiated specimens were forwarded to Science Applications, Inc., and Prototype Development Associates for further testing. Author
