    Striations als Eigenlösungen der Elektronenbewegung im elektrischen Feld (1973)
    Springer
    The European physical journal 263 (1973), S. 299-314 
    Details

    Topics: Physics
    Notes: Abstract A simple model for the motion of electrons in an inhomogeneous electric field is derived. With this model the striations in a weakly ionized low pressure discharge can be explained as a phenomenon of the energy relaxation. In a periodical electric field resonances occur, for which the voltage across one striation equals the average energy gain of an electron between two inelastic collisions, divided by an integer. These resonances are recognized as eigensolutions in the homogeneous field. The influence of the elastic and ineiastic collisions on the damping of the striations is discussed. In a first approximation the energy loss at the elastic collisions can be taken into account by a frictional contribution to the voltage across one striation. This voltage and the energy distribution function in moving striations are calculated and compared with measurements of other authors.

    Örtliche Relaxation der Elektronen-Energieverteilung in hohen elektrischen Feldern (1974)

    Notes: Abstract The motion of electrons in high electric fields is of particular interest due to its special experimental phenomena and its problems in theoretical treatment. We examine the spatial relaxation of electron energy distributions theoretically and experimentally. In the theory we assume a negligible elastic energy loss and a simple model for the inelastic collisions. The distribution function can be separated in two factors depending either on the kinetic energyε or on the total energyX=g3+Φ (Φ: potential energy). In application to the energy relaxation we calculate the relaxation of a humped initial energy distribution to a smoothed equilibrium distribution. The corresponding experiment was performed in the positive column of an argon plasma at a pressure of 3.6 · 10−3 Torr. We measured the electron energy distribution as a function of distance from the cathode with a Langmuir probe using the second derivative method. Good agreement was found between the experimental and theoretical distributions.

    Theorie der „Retrograde Motion“ (1958)

    ISSN: 1434-601X

    Notes: Zusammenfassung Neuere Untersuchungen der „Retrograde Motion“ liefern interessantes experimentelles Material über die rückläufige Geschwindigkeit und die Lage des kritischen Punktes in Abhängigkeit von den verschiedenen Parametern (Stromstärke, Magnetfeld, Druck usw.). Bisher liegt keine Berechnung dieser Beobachtungen vor; verschiedene Modellvorstellungen zur Deutung des Effekts haben sich bei näherer Prüfung als unzureichend erwiesen. Wie eine sorgfältige Diskussion der Kathodenmechanismen zeigt, ist „Retrograde Motion“ bei dem stark kontrahierten, feldbestimmten Ansatz zwangsläufig zu erwarten. Von entscheidender Bedeutung ist hierbei einerseits die gegenseitige Abhängigkeit von Ionen- und Elektronenerzeugung, andererseits die Kopplung der Bewegung der Ladungsträger. Die rechnerische Ausführung erreicht in den wesentlichen Punkten Übereinstimmung mit den Experimenten.

    Notes: Zusammenfassung 1. Unter kritischer Auswertung des Schrifttums werden die Grenzen desSorbitverfahrens nach Werder zum Nachweis von Obst- in Traubenwein abgesteckt. 2. Es wird eine papierchromatographisch-qualitative Arbeitsweise zur approximativen Ermittlung von Sorbit in Trauben- und Obstwein entwickelt. 3. Die Entfernung der die Sorbit-Erfassung störenden Zucker erfolgt durch rasch durchführbare Vergärung mit Preßhefe gemäß dem früher veröffentlichten eigenen Verfahren. 4. Es werden Befunde und Erfahrungen über Sprüh-Nachweis-Reagentien für Hexite neben Zuckerarten anhand experimenteller Erprobungen mitgeteilt. 5. Mittels der entwickelten qualitativen Arbeitsweise Bind Mengen bis herab zu 20 mg Sorbit/l Wein eindeutig nachweisbar. Die neue Methode besitzt gegenüber dem Benzaldehydsorbitverfahren größere Genauigkeit und bessere Reproduzierbarkeit, ist mit relativ wenig Arbeitsaufwand durchführbar und ermöglicht insbesondere die reihenweise Untersuchung von Proben nebeneinander.
