Adaptive optics echelle spectrograph for radial velocity studies

Radial velocity studies represent the most successful method to date for the detection of extrasolar planets. Although radial velocity (vr ) measurement precision of 3 m s –1 is routinely achieved in some programs, it is important to understand and minimize sources of experimental error. Furthermore, velocity variations resulting from astrophysical processes contribute to velocity errors, and m...

Mattauch-Herzog Type Mass Spectrograph with a Two Stage Electrostatic Field

It is very complicated to calculate the secondorder aberrations of complex analyser systems and mistakes are liable to be made. Even if the matrix method is used the tediousness of the calculation is not altered. The usefulness of the matrix representation comes from the fact that the over-all transfer matrix of the total system is easily written as a product of the transfer matrices of various...

An introduction to ion optics for the mass spectrograph.

A mass spectrograph is an instrument that separates and simultaneously focuses ions, along a focal plane, of different mass/charge ratios that are diverging in direction and that have a variable velocity. With these instruments and a spatially sensitive ion detector, simultaneous detection can be employed, which has been shown to improve precision and throughput (as compared to a mass spectrome...

Quantitative velocity modulation spectroscopy.

Velocity Modulation Spectroscopy (VMS) is arguably the most important development in the 20th century for spectroscopic study of molecular ions. For decades, interpretation of VMS lineshapes has presented challenges due to the intrinsic covariance of fit parameters including velocity modulation amplitude, linewidth, and intensity. This limitation has stifled the growth of this technique into th...
