“…Our results shown in figure 2 show carrier lifetime decreased by a factor of 2.5 at a dose of 3x10 16 /cm 2 , but this result should not greatly influence modulation depth. There are other studies of SiGe radiation hardness for transistors in the ATLAS detector [2] and space applications [3] which also are encouraging.…”

“…The basic material of the MIT EAM, Si with Ge near one surface, was exposed to large fluxes of 3 MeV electrons at the Argonne Van De Graff [7][8][9]. Fluxes of a few times 10 16 /cm 2 might be expected at the innermost tracking layer of an LHC detector with upgraded beam luminosity over ten years.…”

At Argonne National Laboratory the High Energy Physics and Center for Nanoscale Materials Divisions are working on a project to develop a new generation of detector readout using high speed data transfer optical devices that can be implemented in particle physics or for long distances. Freespace communications devices offer the potential for reductions in mass, power, and cost of data paths for on-board trigger and readout of tracking detectors. The project involves three areas of study: light modulation, the design and construction of MEMS optical devices, and the control systems for maintaining precise laser light positioning. We demonstrate an optical link in air over one meter and with low error rate at 1 Gb/s. We demonstrate steering of an optical beam over a meter with a precision of 5 micrometers utilizing a MEMS mirror and reflected light in the feedback loop. For early testing, light modulation tests with a fiber link using Li-Niobate modulators and a data generation and error checking chip are done at 1Gb/s. Many companies and universities are developing modulators which will be incorporated into CMOS chips. We are doing radiation hardness studies for one of the materials involved. Laser light will need to be steered on to and kept centered on the detector in the presence of thermal or mechanical motion, etc. This steering will be controlled by MEMS mirrors. Polycrystalline and crystalline silicon based mirror designs are being studied. We review the current status of the project and outline plans for the future development of the system.

“…Because of the DSH size and possibility of on-facility maintenance and upgrading, a distributed ISHM architecture is proposed using wireless remote electronic units (REU's) derived from the RHN and shown in Figure 4 installed around the platform and interfacing to the state-of-health sensors. As discussed elsewhere in this paper, the wireless REU's were developed by NASA under the Extreme Temperature SiGe ETDP program, (Cressler, 2008, and Berger, Garbos, & Cressler, 2008, and Garbos, 2011 and are therefore much more robust and reliable for deep space use than the original RHN units, shown in Figure 5, developed for the X-33 program.…”

“…It was estimated that miniaturization would result in roughly two orders of magnitude improvement in volume, a 10x improvement in weight, and a 5x decrease in power dissipation. Extensive miniaturization as well as enhanced toughness led to the application of the more robust Gen 2 RHN (the REU) using SiGe technology which was funded by NASA under the Extreme Temperature Development Program (ETDP) contract NNL06AA29C using mixed signal SiGe technology, (Cressler, 2008and Berger, et. al., 2008, and Garbos, 2011.…”

Large and complex deep space platforms such as the Deep Space Habitat (DSH) being developed by NASA will require a robust, on-platform, Integrated System Health Management (ISHM) function. Currently the DSH is contemplated to be stationed at the L2 Lagrangian point outbound from the lunar orbit. This will provide a vantage point of the back side of the moon as well as to serve as a jumping off platform for manned trips to Mars, the Moon, or near Earth asteroids. The ISHM function includes the monitoring, diagnostics, prognostics, and failure mitigation strategies and capabilities for any viable failure modes of the DSH. To evaluate a prototype of this approach, NASA has assembled a full scale, ISS derived, DSH prototype at the Marshall Space Flight Center (MSFC), involving a wired ISHM sensor network of over 80 sensors located at various points where early system failure mechanisms may be detected and analyzed. However, it is anticipated that a wired, distributed architecture could involve many pounds of complex cable harnesses and connectors, along with the commonly encountered problems of accessibility, flexibility and maintainability. In the high likelihood that modifications or upgrades are needed, these complexities result in higher design and build cost along with increased operational costs as in-flight anomalies occur that could require the addition of different sensors or different sensor locations. To address these issues, the ISHM team at MSFC is studying a wireless, distributed architecture with on- platform, advanced prognostic and diagnostic capabilities. The approach being considered is based on the X-33 ISHM system which consisted of hardware identical remote health nodes (RHN) and a central vehicle health management computer. Each RHN was very flexible and reprogrammable to enable it to interface directly with all the health monitoring sensors. For application on the DSH, modifications to the RHN are being considered. These changes and resulting upgraded capabilities are described in this paper. As ISHM sensor technology gets smaller, more robust, and includes wireless interfaces for communication and power, the approach will be to connect these wireless sensors by adding state-of-the-art wireless technology to the X-33 developed RHN. This wireless approach eliminates connectors and cables, thus reducing development, installation and life cycle costs while improving reliability and flexibility of the ISHM systems.
