Detection threshold adjustability  
Single +5V operation  
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 from the 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.

RADIATION HARDNESS  
CHARACTERISTICS:  
The HSN-1000 is guaranteed to operate through three critical  
environments: ionizing dose rate [1012 rad(Si)/s], gamma total  
dose [106 rad(Si)], and neutron fluence [5 x 1013 n/cm2]. 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.  
Dose Rate (operate-through): 1 x 1012 rad(Si)/sec  
Total Dose: 1 x 106 rad(Si)  
Neutron Fluence: 5 x 1013 n/cm2  
Approximate Detection Range: 2 x 105 - 2 x 107 rad(Si)/sec  
Maxwell Technologies Specified, Controlled, Tested and  
Guaranteed  
The detection threshold of the HSN-1000 is adjustable within the  
range of 2 x 105 rad(Si)/s to 2 x 107 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.
