BEKANNTMACHUNG DER ANMELDUNG UNDAUSGABE DER AUSLEGESCHRIFT: 26. OKTOBER 1961 ANNOUNCEMENT OF THE REGISTRATION AND ISSUE OF THE EXPLAINING PAPER: OCTOBER 26 , 1961
Die Erfindung betrifft eine Plasma-Eingrenzungs-Vorrichtung mit einem ringförmigen evakuierten Gefäß, mit Mitteln zur Erzeugung eines Magnetfeldes, dessen Feldlinien im wesentlichen parallel zu den Wänden im Inneren des Gefäßes verlaufen, mit magnetischen Spiegeln, die zur Einschnürung der magnetischen Feldlinien in vorgegebenen räumlichen Abständen um das ringförmige Gefäß verteilt sind, und mit Mitteln zur Füllung des Gefäßes mit Plasma.The invention relates to a plasma containment device with an annular evacuated Vessel, with means for generating a magnetic field, the field lines of which are essentially parallel to the Walls run inside the vessel, with magnetic mirrors that help constrict the magnetic field lines are distributed around the ring-shaped vessel at specified spatial intervals, and means for filling the vessel with plasma.
Bekannt ist, daß derartige Vorrichtungen als Erzeuger von Neutronen oder Kernenergie verwendet werden können, wenn es gelingt, die Teilchen über eine hinreichend lange Zeitperiode einzugrenzen, so daß die Kernreaktionen durch Zusammenstöße zwischen den Teilchen, die auf sehr hohen Temperaturen gehalten werden, Zeit haben, mindestens so viel Energie zu erzeugen, wie das Plasma durch die üblichen Verluste, die in derartigen Vorrichtungen auftreten, wie durch Bremsstrahlung, Zusammenstöße mit den Gefäßwänden, Verunreinigungen u. dgl., verliert.It is known that such devices are used as producers of neutrons or nuclear energy if it is possible to confine the particles over a sufficiently long period of time, so that the nuclear reactions result from collisions between the particles at very high temperatures have time to generate at least as much energy as the plasma through the common losses that occur in such devices, such as bremsstrahlung, collisions with the vessel walls, impurities and the like. Loses.
Eine der am meisten verwendeten Arten zur Erzeugung einer derartigen Eingrenzung besteht darin, den mit Plasma gefüllten Innenraum des Gefäßes innerhalb eines magnetischen Feldes mit zeitlich konstanter Feldstärke an jedem Punkt, dessen Feldlinien im wesentlichen parallel zu den Wänden verlaufen, von denen das Plasma isoliert werden soll, anzuordnen. Es ist auch bekannt, in derartigen Einrichtungen, die Gefäße mit linearer Form aufweisen, an den Enden dieses Gefäßes Einschnürungen der magnetischen Feldlinien, sogenannte »magnetische Spiegel« oder »magnetische Flaschenhälse« mit Hilfe zusätzlicher Magnetspulen, die an den Stellen dieser Hälse oder Verschlüsse der magnetischen Flaschen ein stärkeres magnetisches Feld hervorrufen, zu erzeugen. Diese zusätzlichen Wicklungen können prinzipiell entfallen, wenn das Gefäß ringförmig ist, da auf Grund der Geschlossenheit des Innenraumes in sich selbst die Axialbewegung der Teilchen nur eine zyklische Umlaufbewegung derselben zur Folge hat und nicht ein Entweichen derselben in Richtung auf die Wände hin bedeutet. Dieses Entweichen sollen die magnetischen Spiegel in einem linearen Gefäß verhindern, zumindest was das Entweichen der Teilchen in Längsrichtung betrifft. Es wurde jedoch festgestellt, daß es auch bei einem ringförmigen Gefäß vorteilhaft ist, magnetische Spiegel vorzusehen, die an bestimmten Punkten über den Umfang des Ringkörpers verteilt sind, um die zyklische Umlaufbewegung zu verringern. Dadurch sollen Bewegungen der gesamten Plasmamasse verhindert werden, da Plasma -Eingrenzungs -VorrichtungOne of the most common ways to create such a boundary is to the plasma-filled interior of the vessel within a magnetic field with time constant field strength at each point, the field lines of which are essentially parallel to the walls, from which the plasma is to be isolated. It is also known, in such facilities, the vessels have a linear shape, at the ends of this vessel constrictions of the magnetic field lines, so-called "magnetic mirrors" or "magnetic bottle necks" with the help additional magnetic coils, which are at the points of these necks or closures of the magnetic bottles create a stronger magnetic field. These additional windings can in principle not applicable if the vessel is ring-shaped, because of the closed nature of the interior in itself the axial movement of the particles only results in a cyclic orbital movement of the same and does not mean an escape of the same in the direction of the walls. This should escape the magnetic mirrors in a linear vessel prevent at least what the escape of the Particles in the longitudinal direction concerns. It has been found, however, that the same applies to an annular vessel It is advantageous to provide magnetic mirrors that at certain points over the circumference of the ring body are distributed to reduce the cyclic orbital motion. This is supposed to make movements of the entire plasma mass can be prevented as a plasma containment device

diese sich ungünstig auswirken, wie in der Praxis in bezug auf die Aufrechterhaltung hoher Temperaturen und die Stabilität des Systems leicht gezeigt werden kann.these have an unfavorable effect, as in practice with regard to maintaining high temperatures and the stability of the system can be shown easily.
Jedoch auch bei einem Ringgefäß mit magnetischen Spiegeln, die an bestimmten Punkten längs des Umfangs des Ringes verteilt sind, sind die Bewegungen des gesamten Plasmas und davon herrührende Unstabilitäten nicht unterdrückt, und zwar auf Grund der unvollkommenen Dichtheit der magnetischen Flaschenhälse, die derart miteinander verbunden sind, daß sie eine in sich selbst geschlossene Kette, d. h. eine endlose Kette bilden. Ziel der Erfindung ist, diese Dichtheit zu verbessern, derart, daß die Plasmabewegungen innerhalb jeder magnetischen Flasche so selbständig (unabhängig) wie möglich sind.But also with a ring vessel with magnetic mirrors, which at certain points along the Circumference of the ring are distributed, are the movements of the entire plasma and resulting therefrom Instabilities not suppressed, due to the imperfect tightness of the magnetic Bottle necks interconnected in such a way that they form a self-contained chain, i. H. form an endless chain. The aim of the invention is to improve this tightness so that the plasma movements are as autonomous as possible within each magnetic bottle.
Es ist bekannt, daß die Verluste durch Entweichen aus den magnetischen Flaschenhälsen bei Teilchen auftreten, deren Geschwindigkeitsvektor mit der Achse einen Winkel Θ bildet, welcher kleiner als der wie folgt ausgedrückte Grenzwert dafür ist:It is known that the losses due to escape from the magnetic bottle necks occur in the case of particles whose velocity vector forms an angle Θ with the axis which is smaller than the limit value for it expressed as follows:
<9m = arc sin<9 m = arc sin
Dabei ist Bm die magnetische Feldstärke innerhalb des Bereiches der Spiegel und B0 die magnetische B m is the magnetic field strength within the area of the mirror and B 0 is the magnetic field strength
