Abstract
The invention relates to a method for producing neutrons with the aid of a spallation effect. The method includes the diversion of a partial cooling stream out of the main cooling stream and an acceleration of the partial cooling stream in such a manner that vapor bubbles are formed in the vacuum region produced by the acceleration, and after introduction into the main cooling stream, said vapor bubbles act upon generated pressure waves in an attenuating manner during the impingement of a proton beam.
Claims6
Method for producing neutrons with aid of a spallation effect, comprising the following steps:
- providing a liquid target material in a container;
- producing a main cooling stream of the liquid target material;
- aligning the proton beam to the liquid target material, pressure waves being formed due to the impingement of the proton beam in the liquid target material,
- characterized by the further steps:
- diverting a partial cooling stream from the main cooling stream of the liquid target material;
- accelerating the partial cooling stream such that vapor bubbles are formed in a vacuum region produced thereby;
- introducing the accelerated partial cooling stream with the vapor bubbles in the vicinity of the area of the main cooling stream in which the pressure waves are generated in the liquid target material.
