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.

peak measurement.• Foil 350 m across => 1 pixel =
