To achieve the goals of this program improving spectral coverage and output power of monolithic QCL sources as well as the development of a production and manufacturing plan - we propose to develop in collaboration with MIT Lincoln Laboratory a broadly tunable high power source that is based on Eos"proprietary QCL array technology. The current generation of Eos"commercially available fully packaged QCLAs ("The Matchbox") can be tuned over a wavelength range of up to 200 cm-1. The development of the proposed next generation QCLA source with increased power level and spectral breadth will strongly benefit from Eos"s unique expertise and experience in design and fabrication of monolithic QCL sources.

Deoxyribonucleic acid (DNA) is the blueprint on which life is based and transmitted, but the way in which chromatin-a dynamic complex of nucleic acids and proteins-is packaged and behaves in the cellular nucleus has only begun to be investigated. Epigenetic modifications sit 'on top of' the genome and affect how DNA is compacted into chromatin and transcribed into ribonucleic acid (RNA). The packaging and modifications around the genome have been shown to exert significant influence on cellular behaviour and, in turn, human development and disease. However, conventional techniques for studying epigenetic or conformational modifications of chromosomes have inherent limitations and, therefore, new methods based on micro- and nanoscale devices have been sought. Here, we review the development of these devices and explore their use in the study of DNA modifications, chromatin modifications and higher-order chromatin structures. © 2013 Macmillan Publishers Limited.

HYPRES, in collaboration with MIT Lincoln Laboratory and ISQC, proposes to transition superconducting parametric amplifier technology into a robust line of products. In Phase I, we will develop three varieties of superconducting low-noise amplifiers (LNAs) in compact cryogenic microwave packages. These are two types of standing wave devices, lumped-element Josephson parametric amplifier (LJPA) and Josephson parametric converter (JPC), and a traveling wave parametric amplifier (TWPA). To address the primary application of real-time measurements of quantum circuits, the LNAs will be experimentally evaluated, characterized and demonstrated by integrating with quantum bits for their readout. Our plan is to expand the single-channel amplifier product to accommodate the growing complexity of quantum computing and cryogenic detector systems in Phase II. Working towards this goal, we will experimentally perform direct digitization of the LNA output at 4K in Phase I itself with existing superconductor analog-to-digital converter (ADC) chips, and evaluate sensitivity and bandwidth trade-offs. This will be accomplished by leveraging the complete digital data acquisition and processing infrastructure from HYPRES"cryocooled digital-RF receiver product. These data will be used to design an optimized product, enabling simultaneous multiplexed readout of multiple weak analog signals originating at cryogenic temperatures.

The proposed work seeks to establish electric field sensor performance goals and study state of the art electro-optic and nitrogen vacancy diamond electric field sensors.


Noncontact detection of the homemade explosive constituents urea nitrate, nitromethane and ammonium nitrate is achieved using photodissociation followed by laser-induced fluorescence (PD-LIF). Our technique utilizes a single ultraviolet laser pulse (approximately 7 ns) to vaporize and photodissociate the condensed-phase materials, and then to detect the resulting vibrationally-excited NO fragments via laser-induced fluorescence. PD-LIF excitation and emission spectra indicate the creation of NO in vibrationally-excited states with significant rotational energy, useful for low-background detection of the parent compound. The results for homemade explosives are compared to one another and 2,6-dinitrotoluene, a component present in many military explosives.

We propose to combine QmagiQ's strained layer superlattice (SLS) sensor technology with MIT Lincoln Laboratory's novel digital pixel readout integrated circuit (DROIC) to realize an advanced longwave infrared digital focal plane array (DFPA) with high quantum efficiency, dynamic range, and operating temperature. In Phase I, we developed the basic SLS DFPA and demonstrated its extraordinarily high signal-to-noise. In Phase II, we will optimize the DFPA, integrate it into a full-fledged surveillance system, and test it in the field. It's field performance will be directly compared to an identical system with a mercury cadmium telluride FPA.

QmagiQ and MIT-LL will partner to develop a high-performance very longwave infrared digital focal plane array (VLWIR DFPA) suitable for hyperspectral imaging applications. The DFPA will be based on Type-II antimony-based strained layer superlattice (SLS) photodiodes with > 13 micron cutoff, hybridized to a digital readout integrated circuit (DROIC). In Phase I, we investigated the performance of a set of SLS FPAs with the cutoff wavelength systematically shifted from ~ 10 microns to ~ 16 microns. In Phase II, we will build on this effort to maximize quantum efficiency at the longest wavelengths and exploit the DROIC's unique ability to handle large dark current while delivering great signal-to-noise. The resulting sensor will be particularly useful in an infrared hyperspectral imaging system for the stand-off detection of homemade explosives.

Air-Borne Sense and Avoid (ABSAA) cooperative sensors like TCAS and ADS-B are non-developmental off-the-shelf items and as such their employment should be optimized to maximize their effect on levels of safety. The radar subsystem is a new construct whose role and employment has not been previously defined. In addition, the cost of the radar development and production costs are high and dependent on its assigned role and the associated performance requirements. As such a complete assessment of the Size Weight and Power (SWaP) and costs must be included in the establishment of safety requirements. Currently, the Navy is formulating the traceability between Air-Borne Sense and Avoid (ABSAA) radar subsystem and system requirements for UAS platforms including Triton and Fire Scout. This STTR builds on and is coordinated with that effort but focuses on a specific radar ABSAA subsystem, the Common Radar Automatic Collision Avoidance System (C-RACAS) in order to support its development schedule. C-RACAS is targeted for both the Fire Scout and Triton platforms.
