DARPA working on Chip-Scale High Energy Atomic Beams and 19 Other Top Projects

1. From Wired, DARPA working on Chip-Scale High Energy Atomic Beams

Chip-scale integration offers precise, micro actuators and high electric field generation at modest power levels that will enable several order of magnitude decreases in the volume needed to accelerate the ions. Furthermore, thermal isolation techniques will enable high efficiency beam to power converters, perhaps making chipscale self-sustained fusion possible.

The Chip-Scale High Energy Atomic Beams project had a budget of just $3 million, and rather shorter timescales; the plans for fiscal year 2009 include: “Develop 0.5 MeV [mega electron-volt] proton beams and collide onto microscale B-11 target with a fusion Q (energy ratio) > 20, possibly leading to self-sustained fusion.” The energy ratio is the amount of power you get out compared to how much you put in. ITER has a design Q of 10, producing its output with a fifty megawatt input. The Darpa scheme would be twice as efficient.

NOTE: there does not seem to be follow up funding in 2010. However, the 2009 funded work is probably not finished yet. It is not clear what is the result of the work.

The 50 page PDF of DARPA spending plans has some other interesting projects in the 2009 budget and the 471 page pdf 2010 budget.

2. The Low Power Micro Cryogenic Coolers program will attain superior performance in micro-scale devices (e.g. Low Noise Amplifier (LNA’s) IR detectors, RF front-ends, superconducting circuits) by cooling selected portions to cryogenic temperatures. The key approach in this program that should allow orders of magnitude power savings is to selectively cool only the needed volume/device via MEMS-enabled isolation technologies. Such an approach will benefit a large number of applications where performance is determined predominately by only a few devices in a system, e.g., communications where the front-end filter and LNA often set the noise figure; and sensors, where the transducer and input transistor in the sense amplifier often set the resolution. MEMS technology will also be instrumental for achieving micro-scale mechanical pumps, valves, heat exchangers, and compressors, all needed to realize a complete cryogenic refrigeration system on a chip. Transition of this technology is anticipated through industry, who will incorporate elements of the technology in current and future weapon system designs.

4. Nano-Electro-Mechanical Computers (NEMS)

The goal of the Nano-Electro-Mechanical Computers (NEMS) program is to develop nanoscale mechanical switches and gain elements integrated intimately with complementary metal-oxide semiconductor switches. One mechanical switch per transistor will enable the transistor to operate at near zero leakage powers, enabling pico or femtowatt standby operation. The program will also develop mechanical gain elements using physical effects such as giant magnetoresistance, buckling, electromechanical phase transitions, van der Waals forces, and Casimir forces to enable very low-noise, high-frequency amplifiers for low-power, low-noise analog signal processing. Possibilities of using mechanical power supplies and mechanical vibrating clocks could enable electronics that are less susceptible to electromagnetic pulse attacks. Enabling of nanomechanical elements in direct bandgap materials will circumvent problems of gate oxide stability, allowing fast logic with optics functionality. This program will transition into DoD systems via industrial program performers.

5. Chip Scale Autopilot for UAVs

The Chip-Scale Auto Pilot program will develop a new chip-scale subsystem for unmanned aerial vehicles (UAVs), which will provide on-board autonomous capabilities for collision avoidance and maneuvering support. The system will use data from miniature inertial sensors, imagers, and other sensors, and a data-fusion algorithm to produce control signals for the facilities on an existing UAV, such as the Wireless Application Service Provider (WASP). The goal is to allow operators of UAVs in dense urban environments to focus on high-level objectives, and to leave responsibility for survival and maneuvering to the UAV.

In addition, this program will provide a cost effective manufacturing technology for low volume nanoelectromechanical systems (NEMS) and nanophotonics initiatives within the DoD. Transition will be achieved by maskless lithography tools, installed in the Trusted Foundry and in commercial foundries, which will enable incorporation of state-of-the-art semiconductor devices in new military systems, and allow for the cost-effective upgrade of legacy military systems.

8. Disruptive Manufacturing Technologies

The goal of the Disruptive Manufacturing Technologies (DMT) program is to achieve significant and pervasive cost savings, and/or decreases in cycle time, for existing or planned procurements. There has been a long-standing desire to replace traveling wave tube amplifiers (TWTAs), which are pervasive in nearly all electronic warfare (EW), information warfare (IW), radar, and communication systems, with lower cost solid-state components. The DMT program will merge Polystrata™ and GaN technologies to eliminate the need for monolithic microwave integrated circuits (MMICs). The direct product replacement transition candidate for this program is the TWT power amplifier output stage in the AN/ALE-55, Fiber Optic Towed Decoy for the Navy’s new F/A-18 E/F Super Hornet, and the Air Force B1-B and F-15 platforms. It will be replaced with solid-state hybrid microwave integrate circuit (HyMIC) modules developed by merging Polystrata™ and gallium nitride (GaN) technologies. The result will be a 10x reduction in TWTA cost, equaling >$150M for the Integrated Defensive Electronic Countermeasures (IDECM) program, a joint Navy-Air Force program. Beyond developing a replacement for TWTAs, HyMIC technology promises to increase adoption of high performance MMW systems employing mature III-V technologies as well as advance earlier adoption of those using nascent III-V technologies.

11. Quantum OptoMechanics Integrated on a Chip
The objective of this program is to leverage advances in Photonics and Micro fabrication to develop integrated chips capable of exploiting quantum optomechanical applications. Although light is usually thought of as carrying energy but relatively little momentum, light confined to a high-finesse cavity can exert significant force on the cavity mirrors. When the mirror is allowed to vibrate by coupling it to a
mechanical (spring-like) system, energy can be transferred between coupled optomechanical resonators. Depending on the detuning of the cavity, one can obtain either damping (cooling) or amplification (heating) of the mirror motion. Notable achievements in this field are the demonstration of mirror cooling (damping of the internal degree of motion) to sub-Kelvin (6 mK) temperatures and demonstration of radiation driven high-Q, high-frequency (1 GHz) oscillators. With sufficiently high cavity finesse and Q’s of the mechanical system, it is possible to reach a regime in which the mirror motion is no longer thermally limited. Instead, it becomes limited by the quantum mechanical radiation pressure force. Once this limit is reached, it
is possible to take advantage of quantum mechanical effects without having to cool the system. It is anticipated this will result in a new generation of mass-sensing devices and ultra high-Q, high-frequency resonators controlled by light. In optical systems, it will be possible to efficiently squeeze light beyond the standard shot-noise limit producing light sources for infrared detection and quantum information

17. Maintaining Combat Performance
The Maintaining Combat Performance thrust utilizes breakthroughs in biology and physiology to sustain the peak physical and cognitive performance of warfighters operating in extreme conditions. Today, warfighters must accomplish their missions despite extraordinary physiologic stress. Examples of these stressors include extremes of temperature (-20 degrees F to 125 degrees F), oxygen deficiency in mountains, personal loads in excess of 100 lbs, dehydration, psychological stress, and even performance of life-sustaining maneuvers following combat injury. Not only must troops maintain optimum physical performance, but also peak cognitive performance, which includes the entire spectrum from personal navigation and target recognition, to complex command and control decisions, and intelligence synthesis. The Maintaining Combat Performance thrust leverages breakthroughs in diverse scientific fields in order to mitigate the effects of harsh combat environments. For example, understanding the natural mechanisms for core body temperature regulation in hibernating mammals has led to a novel, practical approach for soldier cooling, which is now being evaluated by troops in the far forward combat areas. Other examples include fundamental research elucidating the biological mechanisms of adaptation to extreme altitude, the molecular correlates of muscle fatigue and psychological stress, and natural resistance to disease through dietary nutrients.

The goal of the Vulcan demonstration program, previously funded from PE 0602702E, Project TT-07 (HiSTED Program), is to design, build and ground test an engine capable of accelerating a full scale hypersonic vehicle from rest to Mach 4+. Constant Volume Combustion (CVC) engines have been under development for more than a decade. Considerable progress has been made and the technology is believed mature enough to enable a dramatic new propulsion system capability. CVC engines, when combined with turbine engines, offer the ability to design a new class of Mach 4+ air breathing engines. The Vulcan engine will consist of a CVC engine, a full-scale turbine engine, an inlet and a nozzle. CVC engine architectures could include Pulsed Detonation Engines (PDE’s), Continuous Detonation Engines (CDE’s) or other unsteady CVC engine architectures. The CVC engine would operate from below the upper Mach limit of the turbine engine to Mach 4+. The turbine engine will be a current production engine capable of operating above Mach 2. Key objectives of the program are to integrate the turbine engine into the Vulcan engine with minimal modification to the turbine engine; to operate the turbine engine from rest to its upper Mach limit; and to cocoon the turbine engine when it is not in use. The Vulcan engine will enable full-scale hypersonic cruise vehicles for Intelligence, Surveillance and Reconnaissance (ISR), strike or other critical national missions.
