Fast high resolution echelle spectroscopy of a laboratory plasma

An echelle diffraction grating and a multianode photomultiplier tube are paired to construct a high resolution R= / 2.5 104 spectrograph with fast time response for use from the UV through the visible. This instrument has analyzed the line shape of C III impurity ion emission at 229.687 nm over the lifetime 100 s of the hydrogen plasmas produced at SSX. The ion temperature and line of sight ave...

Prospects of High Energy Laboratory Astrophysics

Ultra high energy cosmic rays (UHECR) have been observed but their sources and production mechanisms are yet to be understood. We envision a laboratory astrophysics program that will contribute to the understanding of cosmic accelerators with efforts to: 1) test and calibrate UHECR observational techniques, and 2) elucidate the underlying physics of cosmic acceleration through laboratory experi...

High Magnetic Field Spectroscopy in Astrophysics

The discovery of very large magnetic fields in white dwarf stars and neutron stars has stimulated interest in the spectroscopy of free atoms in high magnetic fields. We review the discovery of continuum polarization in certain white dwarf stars. We discuss the interpretation of the spectra of the magnetic white dwarfs and the confirmation of the presence of large fields. We describe recent inve...
