Description

Kontaktdetektor. Die Gleichrichterwirkung der Detektoren isst in der Regel, da es sich um die Wirkung singulärer Punkte handelt, nicht gleichmäßig. Gemäß der Erfindung soll die Wirkung des Detektors durch Radiumbestrahlung erhöht werden. Dabei soll die Radiumbestrahlung möglichst so gerichtet sein, --daß sie an der Arbeitsstelle (Spitze) auftritt. Am sichersten wird dies erreicht, wenn die Spitze hohl ist und das Radiumpräparat sich in der Höhlung befindet, dabei kann die Höhlung ähnlich wie die Spitze konisch verlaufen. Es könnte aber auch das Radium sich in seitlichem Kanälen befinden, die neben der Spitze endigen. Soll die Spitze ganz geschlossen bleiben, so wird der hohle Teil der Spitze am vorderen Ende durch dünnes Aluminium o. dgl. abgeschlossen. Will man das Radium unabhängig von der Spitze anbringen, so kann es unterhalb in einer offenen oder ,geschlossenen Kapsel, die austauschbar sein kann, angebracht werden. Man könnte aber auch die ganze Wandung der den Detektor einschließenden Hülle oder Teile dieser Wandung mit einem Radiumpräparat überziehen.Contact detector. The rectifying effect of the detectors eats into the As a rule, since it is the effect of singular points, it is not uniform. According to According to the invention, the effect of the detector is to be increased by irradiation with radium. The radium irradiation should be directed as far as possible so that it reaches the workplace (Tip) occurs. This is most surely achieved when the tip is hollow and the radium specimen is located in the cavity, and the cavity can be similar conical like the tip. But it could also be the radium in the side Channels are located that end next to the tip. Should the tip be completely closed remain, the hollow part of the tip at the front end is made up of thin aluminum or the like. Completed. If you want to attach the radium independently of the tip, so it can be underneath in an open or closed capsule that is interchangeable can be attached. But you could also use the whole wall of the detector Cover the enclosing shell or parts of this wall with a radium preparation.

Der konstruktive Aufbau kann in verschiedener Weise durchgeführt werden. Es ist nur gegebenenfalls der Kristalleinbau bzw. der sonstige Einbau so vorzunehmen, daß die Wirkung des Radiums möglichst auf die aktive Stelle konzentriert wird.The structural design can be carried out in various ways. If necessary, the crystal installation or other installation is only to be carried out in such a way that that the effect of the radium is concentrated as much as possible on the active site.
