Cryogenic electronics is important for a growing number of applications, including superconducting classical computing, superconducting quantum computing and quantum annealing, and superconducting single-photon detector arrays. One of the more difficult aspects about developing a successful superconducting electronics technology at very low temperatures (~10 mK) is the lack of robust commercial …

An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015 Hz to 30×1018 Hz) and energies in the range 124 eV …

Ion beam accelerators are machines providing kinetic energy to charged particles called ions, which bombard the target sample – the material to be irradiated and subsequently analyzed. The target can be a thin foil or a piece of mineral, rubber, textile, tissue, soil or metal. The sample can be an …

Quality standards are defined as documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose. Standards provide organizations with the shared vision, understanding, procedures, and vocabulary needed to meet the expectations of their stakeholders. Because …

The Satellite has a large number of electronic systems and subsystems which are critical to the functioning and its mission. The spacecraft is divided into two sections: the platform or bus and the payload. The platform consists of the five basic subsystems that support the payload: the structural subsystem, the …
Read More »Military Specifications and Standards
Defense standards evolved from the need to ensure proper performance, maintainability and reparability (ease of MRO), and logistical usefulness of military equipment. The latter two goals (MRO and logistics) favor certain general concepts, such as interchangeability, standardization (of equipment and processes, in general), cataloging, communications, and training (to teach people …

Satellite present in an orbit should be operated continuously during its life span. All the satellites require internal power in order to operate various electronic systems and communications payloads that are present in it. The Electrical Power System (EPS) is a vital subsystem whose primary role is to supply satellite …

MIL-STD 810 is a Department of Defense Test Method Standard for environmental engineering considerations and laboratory tests. It is the most popular Military specification used to conduct environmental testing of military products. Given the fact that these products may be exposed to harsh or even extreme conditions, their reliability under …
