Since modern microelectronics are capable of responding in times comparable to gamma pulse risetimes, it is critical to have circumvention techniques that offer protection in the same time frames. We will couple Nu-Trek's ultra fast GaAs detector technology (< 30 ps response time) with Titan/Jaycor's System Hardening Upset Recovery (SHUR) technology for a sub-nanosecond nuclear event detector and ...

Since modern microelectronics are capable of responding in times comparable to gamma pulse risetimes, it is critical to have circumvention techniques that offer protection against the upsets in the same time frames. In the proposed effort our team, Nu-Trek, Titan/Jaycor, and Space Micro, will couple Nu-Trek's ultra fast GaAs Photoconductive detector (PCD) technology (< 30 ps response time already ...

The proposed concept has the potential of meeting in full DTRA's Near Term Simulator Goal for a 20-200 keV, 0.03 cal/cm2, 1,000 cm2, < 20 ns FWHM source. Innovations include (1) Parallel Pulse Forming Network for driving low impedance (< 1 ohm) loads; (2) High voltage (300 kV), high current (40 kA), low jitter (< 3 ns), fast rise time (

CODE (COrps DEvelopment) STEM (Science, Technology, Engineering, and Math) ? Moon Mars and Beyond; DLESE-Powered On-Line Classroom shares the excitement of President Bush's vision of space exploration with 8th grade students. Program fulfills standards-based 8th grade curriculum and will be implemented in two diverse Escondido schools (Grant, Rincon). San Diego County Office of Education will ensu ...

Using Nuclear Event Detectors (NEDs) and Dosimeters, Nu-Trek, SAIC, and Kinney Consulting will demonstrate, feasibility and benefit, of sensors that self-organize during assembly. Sensors are part of the spacecraft avionics and can be reconfigured as needed. Our Space-ZigBee architecture, combines the approach of the ZigBee wireless standard with the SPA-U plug and play interface, for a "wired" ap ...

Capitalizing on AFRL’s Space Plug and Play Avionics (SPA) Initiative, Nu-Trek and SAIC will demonstrate the first SPA-U Self-Organizing dosimeters. The RADFET (small, low power) will measure localized, distributed total dose. The Particle Counting (PIN) Diode Dosimeter (PCDD) will determine the dose, dose rate, and electron and proton spectra. The SPA-U dosimeters include a sensor, SPA-U connect ...

In order to enhance radiation sensing and detection for nonproliferation applications, the DOE is seeking a neutron detector with 100% rejection of gamma rays ¿ which would greatly reduce false positives, a major issue with neutron detectors presently in use. This project will develop low-cost, solid-state neutron detection arrays based on static random access memory (SRAM). (SRAM, which requ ...

Nu-Trek and Raytheon propose to develop a rad-hard-strategic High Anti-Jam (AJ) RF ASIC. Part will be PRF 38585 qualified and sold as OEM product for incorporation in GPS receivers. Presently, ALL High AJ RF Sections are made of DISCRETE components. Also, there are no GPS receivers that are rad-hard-strategic. High AJ RF Section with external filters constitutes an entire RF Section and is 1/5 the ...

We will develop a rad-hard-strategic, 14-bit, 150 MSPS, ADC. Major challenge is maintaining part speed, while hardening it to radiation. The traditional approach to photo-compensation involves adding a “compensating” transistor per “circuit” transistor. This method results in doubling the capacitance and introduces coupling from the substrate at every junction, greatly impairing part’s s ...

The proposed part is a rad-hard, 16-input, 14-bit ADC, with aggregate speed of 200 MSPS. The 16 inputs are sampled individually and can be configured as 16 single-ended inputs or 8 differential inputs. The ADC provides 14 data outputs, a data-ready signal, and an over-range indicator. The digital outputs of the ADC are CMOS low-voltage differential signal (LVDS) outputs. The part will be fabricate ...
