Kinetic Energy of Laser Accelerated Charged Particles in a Plasma and the Possibility of Pair Production
An exact solution of the general equation of motion of charged particles in a medium of refractive index n subjected to irradiation of electromagnetic waves at any intensity and frequency is given. No approxim...

Electron-Photon Interaction
A short survey of recent experimental and theoretical results on the Kapitza-Dirac Effect (the reflection of electrons from a standing light wave) will be given. Higher order calculations show that the effect ...

Magnetic Field Enhanced Energy Increase of Ions Emitted from Laser Irradiated Solid Targets
A ruby laser adjusted to four different power levels, 6, 9, 15, and 30 Megawatt, was focused to a diameter of 0.1 mm on solid targets (W, Ta, Cr, and A1). A magnetic field of flux density B was applied perpend...

Thin Films of Metals and Inorganic Compounds Vacuum Deposited by High Energy Laser
It has been established by many workers that the rate of deposition is an important parameter for the properties of thin films produced in vacuum. However, the velocity of the vapor atoms (kinetic energy) seem...

Linear and Nonlinear Laser Induced Emission of Ions from Solid Targets with and without Magnetic Field
We embarked on a laser program, having previously performed many basic experiments applying electron and ion beams. In the Physics Laboratory of Rensselaer Polytechnic Institute’s Hartford Graduate Center, it ...

The reflection of electrons from standing light waves
Experiments are described in which a slow electron beam is deflected by a standing light wave produced by a high intensity laser. This interaction is believed to occur as a Bragg reflection of the electrons in...

Temperature coefficient of resistance of thin metal films on ceramic surfaces
The temperature coefficients (TCR) of vacuum-deposited thin-metal-film resistors were measured in vacuum, air, argon, and silicone oil, and different characteristics were obtained. The resistors were made by e...

Die Lichtempfindlichkeit von selbstlöschenden Geiger-Zählern aus Glas mit Außenkathode
Es werden einige Untersuchungen durchgeführt, um eine Erklärung für die Lichtempfindlichkeit von selbstlöschendenGeiger-Zählern aus Glas mit Außenkathode zu finden. Der Effekt äußert sich durch das Auftreten von ...

Gasaufzehrung und Gasaustausch bei der Messung niedrigster Drucke im Ionisationsmanometer
Es wird gezeigt, daß das Ionisationsmanometer als Manometer exakt nicht brauchbar ist, da es entweder die Gasart verändert (Gasaustausch) oder.den Druck durch elektrische Gasaufzehrung erniedrigt. Meist erfolg...

Der Mechanismus der elektrischen Gasaufzehrung bei Drucken unterhalb 10−4 Torr
In einer hochevakuierten Glühkathodenröhre besonderer Konstruktion wird zunächst ein sprunghaftes Schwanken des Anodenstromes (mit „Elektronenstromsprung“ bezeichnet) zwischen den Werten 0,1 und 30 mA beobacht...
