Maxwell Technologies’ HSN-1000 radiation-hardened Hybrid
Nuclear Event Detector (NED) senses ionizing radiation pulses
generated by a nuclear event, such as the detonation of a nuclear
weapon, and rapidly switches its output fromthe normal high
state to a low state with a propagation delay time of less than
20ns. The active low Nuclear Event Detection signal (NED) is
used to initiate a wide variety of circumvention functions, thus
preventing upset and burnout of electronic components. The NED
output is also used to initiate both hardware and software recov-
ery. This high-speed, 14-pin hybrid detector is used in electronic
systems as a general-purpose circumvention device to protect
memory, stop data processing, and drive power supply switches
as well as signal clamps.
The HSN-1000 is guaranteed to operate through three critical
environments: ionizing dose rate [10
12
rad(Si)/s], gamma total
dose [10
6
rad(Si)], and neutron fluence [5 x 10
13
n/cm
2
]. In addi-
tion, the device is designed to function throughout the transient
neutron pulse. The hybrids discrete design ensures a controlled
response in these radiation environments as well as immunity to
latchup. Each HSN-1000’s detection level and functionality are
tested in an ionizing dose rate environment. A certificate is pro-
vided with each serialized hybrid, reporting the radiation test
results and guaranteeing its performance. The device is also lot
qualified in the total dose and neutron environments to ensure
performance.
The detection threshold of the HSN-1000 is adjustable within the
range of 2 x 10
5
rad(Si)/s to 2 x 10
7
rad(Si)/s. This detection level
can be preset by Maxwell or adjusted by the user. Less than a
30% variation in detection threshold can be expected over the
entire operating temperature range.
