Atomic hydrogen density measurements in the Tara tandem mirror experiment

Precision measurements with atomic hydrogen masers

Precision measurements of spin interactions with high density atomic vapors

Polarized atomic vapors can be used to detect fields interacting with a spin. Recent advances have extended the sensitivity of atomic magnetometers to a level favorable for fundamental physics research, and in many cases the sensitivity approaches quantum metrology limits. In this thesis, we present a high density atomic K-He comagnetometer, which features suppressed sensitivity to magnetic fie...

Turbulence in Atomic Hydrogen

Understanding the properties of interstellar turbulence is a great intellectual challenge and the urge to solve this problem is partially motivated by a necessity to explain the star formation mystery. This review deals with a recently suggested inversion technique as applied to atomic hydrogen. This technique allows to determine 3D turbulence statistics through the variations of 21 cm intensit...

Temperature, Salinity and Density Measurements in the Coastal Waters of the Rudsar, South Caspian Sea

CTD (conductivity, temperature and depth) data collected in the coastal waters of Rudsar in summer 2008 were analyzed to identify the isothermal layers, thermocline depth and vertical structure of seawater properties. During the survey, probe was released into the seawater column down to 117 m depth. Results showed a vertical variation of temperature between 29°C at the sea surface and less tha...

Electron Cyclotron Heating in the Constance 2 Mirror Experiment* Electron Cyclotron Heating in the Constance 2 Mirror Experiment

Electron cyclotron heating of a highly-ionized plasma in mirror geomctry is investigated. Of primary interest is the experimental diagnosis of the elcctron energy distribution and the comparison of the results of this diagnosis with a two dimensional, time-dependent Fokkcr-Planck simulation. 'Tliese two goals are accomplished in four steps. (1) First, the power balance of the heated and unheate...
