Low voltage electrolytic capacitor pulse forming inductive network for electric weapons

Mays, Thomas Allen. 06 1900 (has links)
Electric weapons, such as the railgun, require a pulse power supply capable of providing reliable highcurrent, high-energy pulses of many megawatts. Pulsed alternators potentially have the same maintenance issues as other motor-generator sets, so a solid-state system would be desirable, but high voltage capacitor systems are not robust enough for the field. We propose here a Low Voltage Electrolytic Capacitor Pulse Forming Inductive Network (LVEC PFIN) which stores power in a relatively low voltage capacitor bank and provides weapon power pulses by first draining the capacitors into a power inductor and then interrupting the flow of current via a switch counterpulsing technique in order to achieve railgun-appropriate voltages. For this thesis, a 13 kJ LVEC PFIN was constructed, using solid-state semiconductor switches to redirect 25 kA of current into a 1 m. load, and the redirection of larger currents is clearly feasible. This technique may be a viable alternative once the energy densities and equivalent series resistances of low voltage capacitors and ultracapacitors reach the necessary levels.

Efficient spin-photon interface for solid-state-based spin systems for quantum information processing and enhanced metrology

Zheng, Jiabao January 2017 (has links)
The holy grail for quantum engineers and scientists is to build the quantum internet that spans over the entire globe. This information infrastructure holds the promise for transmitting information securely, scaling up computing power exponentially and setting the standards for precision measurement at the ultimate limit. Solid-state-based spin systems recently emerge as promising building blocks for the quantum internet. Among these candidates, the negatively charged nitrogen vacancy (NV) center in diamond attracted much attention thanks to its optical addressability, long spin coherence times, and well-controlled electronic orbitals and spin states. However, the non-ideal optical properties of NV poses a challenge to its implementation in quantum technologies. This calls for building photonic structures as efficient spin-photon interfaces for realizing strong interactions with photon modes or efficient out-coupling of its fluorescence. Such interfacing structures are also of great importance for other optically active spin-systems newly found. In this dissertation, chirped dielectric cavities are designed for building NV as fast single photon sources via broadband Purcell enhancement, using an inverse simulation approach to maximize the broadband absorption of the atomically thin absorbers. Simulated NV-cavity coupling indicates broadband Purcell factor of ∼> 100. Next, to realize coupled NV-cavity systems over large scale, a self-aligned nano-implantation technique is investigated using a lithographically defined hybrid mask for both precision pattern transfer and nitrogen implantation. Measured results show single-NV per cavity yield of ∼ 26±1% and 5-fold Purcell induced intensity enhancement. Finally, chirped circular gratings are designed for efficient collection from the NV for remote entanglement and precision sensing. Simulated grating structures present near-unity collection efficiencies. These demonstrated techniques and structures are also applicable to other solid-state-based spin systems.
