Project 7,1-17/RS(CC)-8 - Test of Efficiency of Field Collective
Protector
\
The collective protector in an OCE structure was sheared from the
inlet pipe when the structure turned over and consequently failed to
collect a sample,
The only positive information obtained fran this
project is that the filters were undamared by the blast pressure at
this specific distance and that the equipment would probably have
operated satisfactorily,if the structure had remained upright.
The
other collective protector in the boat dowmvind sank prior to the test,
Its removal from the 1000 foot structure did not involve the loss of
F
any information since the blast would have prevented obtaining any data
concerning the 1000 foot structure.
‘Two new collective protectors were
obtained for installation in the ICM dovmrind in tests Yoke and Zebra,

Particle Size of Material in Cloud
Despite the fact that CCE structures were moved a considerable
distance the impactors operated properly and collected samples of dust
stirred up by the explosion.
No final correlation with particle size
has yet been mide since it is planned to study the slides with an
electron microscope at Edgewood, Md,
<A cascade inpactor will be
placed in an LOM located dowmvind about 2500 yards and also one ina
drone plane at 16,000 feet for test Yoke.

Thermal Radiation Papers
Only a few samples of Dr. Penny‘s paper on the plyboard squares
were not burned,
In test Yoke the papers will be placed at sreater
distances than at test X-Ray in order to obtain additional points,
