The basic firing mechanism for detonating the Mike
device is a clock-activated system located on Elugelab.
Depend-~
ing on the results ofsextensive tests to be made prior to 1
October, the timing and firing sequence may be started by remote r-f control.
The purpose of the tests is to insure that
the remote system will be as safe as is humanly possible to
make it.
As an alternate to the remote starting, a straight
clock-timed start is contemplated, i.e., with no r-f start control.
<A safety switch in series with the arming and firing cable
may be located on Parry Isiand in order to provide an additional
sefety feature for the Firing Party. Two television channels be-
tween Elugelab and the USS Estes will present pictures of the
cryogenics monitoring systems and the timing, power on, arming
and firing circuits.
Within these two channels sufficient cross
channel information will be presented to provide a back-up should
one channel go out or become unintelligible.
In addition, a sep-
arate radio channel is provided such that the firing system can
be stopped at any moment up to zero time.
There are also several
we
"go=no go" interlock systems built into the firing circuit, any
