Principal use in commercial instruments for measurement of Earth- gravity gradients in geo-physical surveying and exploration for oil. Gradiometer design integrates accelerometers for operation in differential mode. Incorporates several magnetically levitated proof masses. Three-axis superconducting gravity gradiometer based on flux quantization and Meissner effect in superconductors and employs superconducting quantum interference device as amplifier. Gravity gradients measured even on accelerating platforms. Three-Axis Superconducting Gravity Gradiometer We will present an update of these developments and discuss the future directions of the quantum gravity gradiometer project. Along with this development, we are developing technologies at component levels that will be more suited for realization of a space instrument. We have demonstrated atom interferometer operation in the Phase I period, and we are implementing the second generation for a complete gradiometer demonstration unit in the laboratory. During the free fall, a sequence of laser pulses is used to split and recombine the atom waves to realize the interferometric measurements. Then they are allowed to freefall in vacuum as true drag-free test masses. In this approach, atoms are first laser cooled to micro-kelvin temperatures. Atom interferometers have been demonstrated in research laboratories for gravity and gravity gradient measurements. The overall approach is based on recent advances of laser cooling and manipulation of atoms in atomic and optical physics. It also allows measurements of the gravity gradient tensor components for 3D mapping of subsurface mass distribution. The atom interferometer utilizes atomic particles as free fall test masses to measure inertial forces with unprecedented sensitivity and precision. Quantum interferometer gravity gradiometer for 3D mapping is a project for developing the technology of atom interferometer-based gravity sensor in space. Progress towards a space-borne quantum gravity gradiometer We will also discuss our implementation plan for the next generation instrument. We will then describe the technical implementation of the laboratory setup and report its status. In this paper, we will briefly review the principles and technical benefits of atom-wave interferometer-based inertial sensors in space. This is our first step towards a new spaceborne gradiometer instrument, which can significantly contribute to global gravity mapping and monitoring important in the understanding of the solid earth, ice and oceans, and dynamic processes. Maleki, Luteįunded by the Advanced Technology Component Program, we have completed the development of a laboratory-based quantum gravity gradiometer based on atom interferometer technology. The eponymous Alpha Teens, which consist of Axel Manning (the main character), Catalina Leone, Crey Kingston, Zack Hawkes, and Ollie Sharker, test prototype vehicles and weapons for Lee Industries, and use these prototypes to combat criminals, particularly the sadistic Alexander Paine.Quantum Gravity Gradiometer Development for Space The series focuses on the adventures of five teenagers in the fictional location Landmark City. A.T.O.M. – Alpha Teens on Machines ( Action Man A.T.O.M. in some countries) is a French-American superhero animated television series produced by SIP Animation in association with Jetix.
