Specifically for these tests.
The carriers were unguided, rail-Launched bal-
listic rockets, with variations of weight and drag ‘for altitade control (see
Chapter 6).
Each carrier had a 226- to 235~ec band telemetering systen aboard equipped
with from four to eighr scbcarriers.
The FM-FM receiving and recording station
was located near the launch site oa Johnston Island (see Chapter 9}.
All six
carriers contained transducers for measuring neutron and gamma-ray fluxes.
The
meutron transducer consisted of activation foils counted by a scinrillometer
circuit during the fall time of the noose.
Gamma-ray dose rates vere measured
by scinrillometers and total dose by silwer-activated phosphor-glass and fils.
In addition, the two rocket stations nearest the burst attempted measure-~
went of X-ray and total theresl inputs.
Both transducers utilized ballistic
calorimeters containing resistance wires comnacted in a four-are bridge.
Total
thermal radiation was absorbed by a polished alumimm cove mounted inside a
truncated cone.
Y-rays vere filtered by aluminium and beryllium filters.
six carriers also contained film packs for measuring gawum-ray dose.
These
Hoses
were designed for parachute retardation and for recovery from the ocean.
The Redstone carried two h-kec diagnostic systems for weasuring high explosive transit time and early alpha of the primary bomb.
This system and the
warhead fuzing system vere sonitored by 226-ec telemetry equipment.
All six instrument carriers and the Redstone vere tracked by two MIDOT
(radio interferometer positioning system) stations for postshot deteraination
of the position of transducers relative to the burst.
The transmitters aboard
each carrier served as beacons for MIDOT to follow.
,
Two radiochemical sampling ooses vere to be carried through the Teak debris
by two stages of the modified LaCrosse motors.
These vere to have sampled,
sealed, and lowered tc the water a collection of the burst residue for laboratory analysis.
.
4 system for ceasuring wind welociry at 250,000 feet alcirude was designed
to perait adjustment of the rad-ches sampler trajectories to increase the likelihood of sending the sacpler through the densete debris.
This seasurenent was
made by utilization of 5-ca chafi, carried to altitude on a@ Deacon-Arrow II
4
rocket, ejected, ard tracazed by MSQ radar.
