... The total optical path through the NPOI can be found by adding various contributions listed in the files npoi/stations.config , npoi/fdl.config , and npoi/6way.config . For the purpose of calculating delay constant term and optical path lengths, we break up the paths into segments of four types, associated with siderostat station, delay line, beam combiner number (ID), and beam combiner input number. ... In file 6way.config , about 4m of path through the beam combiner are not included. ...

... Trapped Motion . ... The trapping of particles by magnetic fields was first studied by Kristian Birkeland in Norway, starting around 1895. ... Perhaps the most interesting story of that era concerns Nicholas Christofilos , a Greek elevator engineer whose avocation was the study of particle motion in magnetic fields. ... Atomic bombs produce large numbers of energetic electrons, and Christofilos hoped that such electrons would become trapped in the magnetic field as an artificial radiation belt. ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

... Kellermann and Pauliny-Toth [5] showed that the maximum brightness temperature that a source can sustain is limited by the cooling due to inverse Compton scattering in the Thomson regime, which rises rapidly when the source exceeds TB > 3 в 1011 K. As pointed out by Crusius-Waetzel [6], brightness temperatures higher than 1012 K can be produced by monoenergetic electron, since the GHz photons can emerge from the source without being absorbed by low energy electrons. ...
