Abstract: Disclosed is a system and method for implementing a network enabling an interoperable exchange of electronic payment information, which connects two parties to a transaction using established rules, technology, and trust model. Such systems and methods provide a shared set of rules and common APIs, and enable validation of the accuracy of all data exchanged via API. In order to maintain data, the systems and methods described herein enable each participant to only see interactions and information that is relevant and permissioned to such participant, all while maintaining no central data store for the sensitive electronic payment information. Each participant is vetted and authorized by a system administrator as a validated “Credential Service Provider” (“CSP”) and governed by rules created and managed by the administrator. Further, an auditable trail of all transactions is maintained by logging metadata to track events and changes to permissions.

Abstract: A travelling wave tube of the coupled cavity type including a slow wave propagating structure comprised of a linear array of transverse plates axially spaced apart to provide a sequential series of interposed cavities, each of the plates having a cavity coupling aperture radially spaced from an electron beam transmitting aperture and spanned by at least one thermally conductive, dielectric member made of diamond material, which has respective surface areas disposed in thermal contact with opposing side walls of the cavity coupling aperture.
