Visible, EUV, and X-Ray Spectroscopy at the NIST EBIT Facility

April 24, 2004
Author(s)
John D. Gillaspy, B Blagojevic, Paul A. Dalgarno, K Fahey, V Kharchenko, J M. Laming, L Logosi, E-O Le Bigot, K Makonyi, L P. Ratliff, E Silver, H. Schnopper, E Takacs, J N. Tan, H Tawara, K Tokesi
After a brief introduction to the NIST EBIT facility, we present the results of three different types of experiments that have been carried out there recently: EUV and visible spectroscopy in support of the microelectronics industry, laboratory

Highly Charged Ion Bombardment of Silicon Surfaces

J E. Sanabia, S N. Goldie, L P. Ratliff, Lori S. Goldner, John D. Gillaspy
Visible photoluminescence from Si (100) surfaces irradiated by highly-charged ions has recently been reported. 1 This discovery has potential applications in silicon-based display technology and other opto-electronic devices and detectors. In an attempt to

EBIT Diagnostics Using X-ray Spectra of Highly Ionized Ne

M Matranga, M Barbera, A Maggio, G Peres, S Serio, E Takacs, E Silver, John D. Gillaspy, H. Schnopper, J M. Laming, J. Beeman, E. E. Haller, N. Madden
We have carried out a detailed analysis of highly ionized neon spectra collected at the NIST EBIT using an NTD germanium X-ray microcalorimeter developed at the Harvard-Smithsonian Center for Astrophysics [1]. Our attention was focused especially on the Ne

X-Ray Spectroscopy of Trapped Ions With a Microcalorimeter on the NIST Electron Beam Ion Trap

E Takacs, John D. Gillaspy, L P. Ratliff, K Makonyi, J M. Laming, E Silver, H. Schnopper, M Barbera, J. Beeman, E. E. Haller, N. Madden
The electron beam ion trap (EBIT) was invented about 15 years ago. Judging from the wide range of experiments performed on the machine since its inception, EBITs have become one of the most successful devices to Produce, trap and study the structure and
