IS☉IS hardware being prepared for its mission, EPI-Lo hardware shown in 2017. Integrated Science Investigation of the Sun or IS☉IS, is an instrument aboard the Parker Solar Probe, a space probe designed to study the Sun. IS☉IS is focused on measuring energetic particles from the Sun, including electrons, protons, and ions. [1]
One rotating magnetic field pulse of the PFRC-2 device during an experiment. The Princeton Field Reversed Configuration (PFRC) is a series of experiments in plasma physics, an experimental program to evaluate a configuration for a fusion power reactor, at the Princeton Plasma Physics Laboratory (PPPL).
Magnetic (or solar) switchback is a rapid polarity reversals of the radial heliospheric magnetic field. [4] These events have been termed "switchbacks", when referring to the change in magnetic field direction, or "velocity spikes", when referring to the sharp increase in solar wind speed. [3] The switchbacks generate heat that warms solar ...
Frist Campus Center is a focal point of social life at Princeton University. The campus center is a combination of the former Palmer Physics Lab, and a modern addition completed in 2001. The campus center is a combination of the former Palmer Physics Lab, and a modern addition completed in 2001.
Magnetic reconnection is a breakdown of "ideal-magnetohydrodynamics" and so of "Alfvén's theorem" (also called the "frozen-in flux theorem") which applies to large-scale regions of a highly-conducting magnetoplasma, for which the Magnetic Reynolds Number is very large: this makes the convective term in the induction equation dominate in such regions.
Eugene Newman Parker (June 10, 1927 – March 15, 2022) was an American solar and plasma physicist.In the 1950s he proposed the existence of the solar wind and that the magnetic field in the outer Solar System would be in the shape of a Parker spiral, predictions that were later confirmed by spacecraft measurements.
The United States Senate is the upper house of Congress. Princetonians have a long history of service in the Senate. The Senate of the First Congress included three Princeton alumni (Oliver Ellsworth of Connecticut, [1] William Paterson of New Jersey, [2] and John Henry of Maryland [3]), two more who attended Princeton but did not graduate (John Brown of Virginia, later Kentucky, and Benjamin ...
A railway zig zag or switchback is a railway operation in which a train is required to switch its direction of travel in order to continue its journey. While this may be required purely from an operations standpoint, it is also ideal for climbing steep gradients with minimal need for tunnels and heavy earthworks. [ 1 ]
