HSN-1000 Nuclear Event Detector VB 8 9 VH VL 14 Threshold Adjust 1 10 k Ω 2 Detector (Pin Diode) BIT 6 Amplifier NED Pulse Timer LED 7 GND 5 C 4 RC Logic Diagram DESCRIPTION: • • • • • • • • • 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 recovery. 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. Detects ionizing radiation pulses 100% tested/certified detection threshold level Adjustable circumvention period 100% testable with built-in test Detection threshold adjustability Single +5V operation Radiation hardness guaranteed Compliant to MIL-PRF-38534 Class H1 Flat pack (F) or DIP (L) packages RADIATION HARDNESS CHARACTERISTICS: • • • • • 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 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 addition, the device is designed to function throughout the transient neutron pulse. The hybrid’s 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 provided 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 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. 1.

HSN-1000 Nuclear Event Detector Table 2. Notes 1. Standby mode is the normal state of the device, defined as having the NED output (pin 2) in the “high” state. 2. Operational mode is in effect during the timeout period of the NED signal, characterized by having the NED output in the “low” state, causing the greatest current draw of the device. 3. BIT electrical characteristics are not guaranteed over the radiation range. 4. BIT may not meet specification when only a resistor is used to adjust the detection level. To use BIT in this situation, it is advised that a series resistor/capacitor...
