The Wide Field Spectrograph ( WiFeS )
This paper describes the Wide Field Spectrograph (WiFeS) under construction at the Research School of Astronomy and Astrophysics (RSAA) of the Australian National University (ANU) for the ANU 2.3m telescope at the Siding Spring Observatory. WiFeS is a powerful integral field, double-beam, concentric, image-slicing spectrograph designed to deliver excellent thoughput, wavelength stability, spect...
متن کاملMattauch-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...
متن کاملAn 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...
متن کاملA Rapidly Converging Phase Field Model
We propose a phase field model that approximates its limiting sharp interface model (free boundary problem) up to second order in interface thickness. A broad range of double-well potentials can be utilized so long as the dynamical coefficient in the phase equation is adjusted appropriately. This model thereby assures that computation with particular value of interface thickness ε, will differ ...
