DESCRIPTION

Buried cone, buried layer Titan, August 2008. Buried cone buried layer comments. Is it possible laser didn’t hit bottom every time? Intrinsic prepulse -- 19s7, 21s5 - the latter has very well defined peak. Former much broader. - PowerPoint PPT Presentation

Buried cone buried layer comments

• Is it possible laser didn’t hit bottom every time?– Intrinsic prepulse -- 19s7, 21s5 - the latter has very well defined

peak. Former much broader.

– 50 mJ prepulse -- 21s3, 21s6, 21s7 have -- peak definition improves with later shots.

• Some of the well-defined spots weren‘t in the center of the foil. The foils don’t seem to be offset that much - see 21s5,7. Need to work out relationship of x-radiographs to target images to check.

• Foil is not much larger than peak - but checked measuring routine against lineouts, and find results OK.
