![]() Ion temperature and the ion velocity distributions may also be extracted from the fluorescence data since available hyperfine splitting data allow for the Kr II 5d(4)D(7/2)-5p(4)P(5/2)(∘) transition lineshape to be modeled. From these measurements, it is possible to measure velocity as krypton ions are accelerated from near rest to approximately 21 km/s (190 eV). The 728.98 nm Kr II transition from the metastable 5d(4)D(7/2) to the 5p(4)P(5/2)(∘) state was used for the measurement of laser-induced fluorescence within the plasma discharge. We present the application of laser-induced fluorescence of singly ionized krypton as a diagnostic technique for quantifying the electrostatic acceleration within the discharge of a laboratory cross-field plasma accelerator also known as a Hall effect thruster, which has heritage as spacecraft propulsion. Kr II laser-induced fluorescence for measuring plasma acceleration. This session will link the CCC and SA (using Codec VC). Experts in the field of Accelerator science will be available to answer the students questions. Raich Video Conference with the CERN Control Center. Future system enhancements will provide additional user functionality and support more simultaneous users.ĪT2 DS II - Accelerator System Design (Part II) - CCC Video Conferenceĭiscussion Session - Accelerator System Design (Part II) Tutors: C. Initially, operations consist of user requirements development, measurement sensor deployment and use, and data recovery on the ground. Ground Operations Equipment is deployed to complete the command, control and data telemetry elements of the SAMS- II implementation. SAMS- II on-orbit hardware is comprised of two basic building block elements: a centralized control unit and multiple Remote Triaxial Sensors deployed to measure the acceleration environment at the point of scientific research, generally within a research rack. The Space Acceleration Measurement System-II, or SAMS- II, detects vibrations present while the space station is operating. The Space Acceleration Measurement System-II provides researchers a consistent means to understand the vibratory conditions present during experimentation on the International Space Station. With initiation of scientific studies comes a need to understand the environment present during research. The International Space Station opens for business in the year 2000, and with the opening, science investigations will take advantage of the unique conditions it provides as an on-orbit laboratory for research. ![]() Space Acceleration Measurement System-II: Microgravity Instrumentation for the International Space Station Research Community Investigators seek to better understand the vibration environment on the space station to enable future research. Results will be used to generalize the types of vibrations affecting vibration-sensitive experiments. Space Acceleration Measurement System (SAMS- II) is an ongoing study of the small forces (vibrations and accelerations) on the ISS that result from the operation of hardware, crew activities, as well as dockings and maneuvering. ![]()
