Publication number: 20240036094Abstract: In a general aspect, radio frequency (RF) electromagnetic radiation can be detected using vapor cell sensors. In some aspects, a system includes a laser system that is configured to generate laser signals that comprise first and second laser signals. The system also includes an optical comb generator and a vapor cell sensor. The optical comb generator is configured to generate a comb spectrum based on the first laser signal. The comb spectrum includes comb lines at respective comb frequencies. The vapor cell sensor contains a vapor and is configured to generate an optical spectrum based on interactions of the vapor with the comb spectrum and the second laser signal. The system also includes an optical detector that is configured to detect the property of the optical spectrum at one or more of the comb frequencies.Type: ApplicationFiled: April 5, 2023Publication date: February 1, 2024Applicant: Quantum Valley Ideas LaboratoriesInventors: Katelyn Dixon, Kent Arnold Nickerson, Donald Booth, James P.

Publication number: 20240036095Abstract: A system for the automated validation of a semi-anechoic chamber (SAC) is disclosed. The system includes a receive assembly and a transmit assembly, each configured to autonomously relocate within the SAC. The system also includes a local client communicatively coupled to the transmit assembly. The local client is configured to send a validation arrangement to the transmit assembly describing a validation location and a distance. The transmit assembly is configured to receive the validation arrangement, move the transmit assembly to the validation location and send an instruction to the receive assembly, the instruction describing the distance. The receive assembly is communicatively coupled to the transmit assembly and configured to receive the instruction and move the receive assembly such that a separation between the transmit and receive assemblies is restored to the distance. Each validation arrangement corresponds to a validation point. A plurality of validation points defines a test volume.Type: ApplicationFiled: January 31, 2023Publication date: February 1, 2024Inventor: Phillip C. MILLER

Publication number: 20240036096Abstract: To achieve decreased noise and improved sensitivity by reducing parasitic capacitance in a charge detection sensor. The charge detection sensor includes a detection element, a detection electrode, and a contact. The detection element is provided on one surface of a semiconductor substrate and detects a charge. The detection electrode is provided on another surface different from the one surface of the semiconductor substrate. The contact penetrates the semiconductor substrate and electrically connects the detection electrode and the detection element. Since no wiring layer is formed between the detection element and the detection electrode, the parasitic capacitance is reduced.Type: ApplicationFiled: August 11, 2023Publication date: February 1, 2024Inventors: JUN OGI, YURI KATO, NAOHIKO KIMIZUKA, YOSHIHISA MATOBA, KAN SHIMIZU
