Six stations were located at 40,000, 50,000, 60,000, and 80,000 ft altl-

tude directly beneath the burst, and at 30,000 ft from the burst along the
bomb axis and perpendicular to it.

Each carrier had a 226 to 235 Me band telemetering system aboard
with from four to elght subcarriers. The FM-FM receiving and recording
station was located near the launch site on Johnston Island.
All aix carriers contained transducers for measuring neutron and gamma
ray fluxes. The neutron transducer consisted of activation foils that were

counted by a scintillometer circuit during the fall time of the nose,

Gamma

rays were measured as dose rate by scintillometers and as total dose by

silver-activated phosphorglass and a densitometer.
In addition, the two stations 30,000 ft from the burst measured x-ray
and total thermal inputs at their locations. Both transducers utilized ballistic
calorimeters containing resistance wires connected in a four-arm bridge.

The total thermal was absorbed by a polished aluminum cone mounted inside
a truncated cone. The x rays were filtered through beryllium discs of 50

and 70 mil thickness. The remaining energy impinged upon the calorimeter.
These six carriers also contained film packs for measuring high gamma

flux and material samples for effects evaluation.

The noses were designed

for parachute retardation and for recovery from the ocean,

WH fuzing system was monitored by 226 Mc telemetry equipment.
All six instrument carriers and the Redstone were tracked by two
MIDOT (radio interferometer positioning system) stations for relative positioning of transducers and the burst. The transmitters aboard each carrier
served as the beacon.
3.
Two radiochemical sampling noses were to be carried through the
Teak debris by two stages of the modified-LaCrosse motors. These sampled,
sealed, and lowered to the water a collection of the burst residue for laboratory analysis.
4.
A system for measuring wind velocity at 250,000 ft altitude was
designed to permit adjustment of the radchem sampler trajectories to increase
the likelihood of sending the sampler through the densest debris. This
measurement was made by carrying 5 cm chaff to altitude on a Deacon-Arrow
IE rocket, ejecting the chaff, and tracking it with a MSQ Radar.
5.
The RF attenuation measurements were made by carrying eight
transmitters (four operating near 225 Mc and four near 1500 Mc) aloft on
eight two-stage rockets and recording received si
strength at two separate locations. Six of these carriers were

Optical instrumentation included
high speed and longer time photography through three different narrow band filters, a high resolution spectral record, plate cameras located at each MIDOT station for location of
burst position, and black and white and color documentary photography.
7.
The warheads used on the high altitude shots were modified, installed, checked out, and armed by Program 32.
All equipment used on Teak operated as designed with the following exceptions:

The two radchem samplers appeared to suffer structural damage
at the time of second-stage burning, became unstable, and fell back to the
