A New Mass Spectrograph with Very Large Dispersion

fects are described as a function of ß0 under a constant value of 3 0 . Fig. 18 illustrates the results. Only by the present instrument the image defects can be decreased with decreasing ß0 .

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...

A New Spectrograph Platform for Auroral Studies in Svalbard

A versatile spectrograph platform has been installed by University College London at the Adventdalen Observatory in Svalbard. The platform was primarily built to support the Southampton University study of proton aurora and smallscale auroral features. It has successfully recorded the spectral profile of the Doppler broadened H-beta emission line (486.1 nm) and observed the predicted red shifte...

The Spectrograph

JILA Fellow John Hall will deliver the 2006 Richard C. Lord Lecture on May 2, on “Optical clocks, combs and coherence: defining and measuring optical frequency.” Born in 1934 in Denver, Hall is an alumnus of the Carnegie Institute of Technology, where he received B.S., M.S. and Ph.D. degrees. He conducted postdoctoral studies at the Department of Commerce’s National Bureau of Standards, now cal...
