CMOS-Compatible Integrated Spectrometer Based on Echelle Diffraction Grating and MSM Photodetector Array

open access: yesIEEE Photonics Journal, 2013
We demonstrate an integrated spectrometer-on-a-chip composed of an echelle diffraction grating (EDG) and metal-semiconductor-metal (MSM) waveguide photodetector array based on silicon-on-insulator (SOI).

Depth profile CF LIBS analysis of the wall deposited layer in the COMPASS tokamak after LiSn testing campaign

open access: yesNuclear Materials and Energy, 2023
Plasma-facing materials in tokamak nuclear reactors are subject to intense heat and radiation. The design of liquid metal (LM) divertor walls has several advantages over the solid counterparts.

Investigation of low-temperature plasmas formed in low-density gases surrounding laser-produced plasmas

open access: yesNukleonika, 2023
Low-temperature plasma production is possible as a result of photoionization using high-intensity extreme ultraviolet (EUV) and soft X-ray (SXR) pulses. Plasma of this type is also present in outer space, e.g., aurora borealis.

ACTIVIVE PHENOMENA OBSERVED IN ATMOSPHERIC LINES OF THE HERBIG AE STAR HD163296

open access: yesOdessa Astronomical Publications, 2008
We present new results of a high- resolution spectroscopic investigation of the young Ae Herbig star HD163296. Nineteen spectra of this object had been obtained on May 8 - 10, 2002 at the ESO with the FEROS high-resolution echelle spectrometer (R=48000 ...

The Lick Observatory Hamilton Echelle Spectrometer [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1987
The Hamilton Echelle Spectrometer, recently installed at the coudé focus of the Shane 3-m telescope, is a high dispersion spectrograph optimized for use with large format CCD's. It was designed primarily for high resolution (R=50,000) wide bandpass spectroscopy of point-like sources down to a limiting magnitude of about V=16.5, over the 0.34 μm to 1.1 ...

CHIRON – A new high resolution spectrometer for CTIO

open access: yesEPJ Web of Conferences, 2011
Small telescopes can play an important role in the search for exoplanets because they offer an opportunity for high cadence observations that are not possible with large aperture telescopes.

CIRCUMSTELLAR ACTIVITY OF THE HERBIG AE STAR HD163296

open access: yesOdessa Astronomical Publications, 2007
We present new results of a high-resolution spectroscopic investigation of the young Ae Herbig star HD163296. Nineteen spectra of this object had been obtained on May 8 - 10, 2002 at the ESO with the FEROS echelle spectrometer installed at the 1.52m ...
