Abstract: In an electromagnetic device a magnet arrangement is provided having an electromagnet and a permanent magnet, with the pole faces of the permanent magnet abutting the core of the electromagnet on both sides of the end portions of the coil of the electromagnet and the end portions of the core of the electromagnet forming or supporting the pole pieces of the magnet arrangement. The poles of the permanent magnet are adjacent the like poles of the electromagnet when the electromagnet is energized, and the maximum value of the energizing current of the electromagnet is sufficient but not greater than necessary for reaching the first practical saturation value of flux density in the pole ends of the core of the magnet arrangement with the permanent magnet removed therefrom.

Abstract: A plasma device having low thermal noise, which results in a high signal-to-noise ratio (SNR) of the plasma device. The plasma device includes devices with a plasma that is responsive to electromagnetic radiation and/or electrical signals. In various configurations, the plasma device has a plasma in which the temperature, resistance, pressure, and/or collision frequency are at a level sufficiently low to produce an acceptable level of noise. In another configuration, the operating frequency of the plasma device is at a level sufficiently high to produce an acceptable level of noise. Decreasing the noise level results in increasing the signal-to-noise ratio and increasing the data rate. The plasma temperature is reduced by operating the plasma device in the afterglow state. The plasma electron temperature is reduced by confining high energy electrons in a potential well and by using an electron emitting filament.
