It was apparent that if the sampler rocket struck

In fact, samples could be so large as to
require hot recowery techniques.
Thus far, sempler size based on conventional cloud-rise assumptions has
been considered.
A smaller sample vould be obtained by the apogee rocket if
the abrupt hydrodynamic debris rise occurred, since the cloud disaeter would
be larger (about 40,000 feet), and the sampler less effective.

Debris Characteristics at 125,000 Feet
& device identical to that planned for the Teak 250,000-foot burst was
planced for detonation st 125,000 feet.
Since it was planned to label the
debris from this weapon, LASL (J-11) requested that Sandia aiso obcain a
sample frow the lower Orange burst.
Teak burst actually occurred at 252,000
feet and Orange at 141,000 feet.
Barst Phencuenologyfor 125,000 Feet Altitude.
A different sampling
technique was used for the lower Orange shot, since it did not seem feasible
to sample a hot, relatively dense cloud.
Furthermore, rockets used in smmpling
could be deviated from the wertical only by a limited amount.
Therefore, it
was determined to launch the sampler rocket at an angle which would allow
sampling of the debris cloud at an elevation of 160,000 feet, or 35,000 feet
above planned burst point.
Details of debris behavior in the burst wicinity were of less concern
than the eventual cloud-debris diameter and the rise behavior.
This was
fortunate, since the burst at 125,000 feet had received less intense theoretical consideration chan its higher companion shot.?
Ie is known that energy
radiated from the weapon is deposited relatively close, so it was expected
that the eventual bydrodyaanic behavior should be closer tu tiat at sea icval
than for Teak shot.
