METHOD FOR DETECTING RADIATION AND EXAMINATION DEVICE FOR THE RADIATION-BASED EXAMINATION OF A SAMPLE |
摘要 |
<p>A method for detecting radiation during the examination of a sample (1) comprises the steps of generating the radiation, more particularly X-ray radiation or proton radiation, by means of a source device (10), passing the radiation through the sample (1), and detecting the radiation by means of at least one photoelectric solid-state detector (20) containing a photoconduction section having a predetermined response threshold and a potential well section for taking up free charge carriers. The solid-state detector (20) is a GaN- or GaAs-based semiconductor detector and the potential well section contains a two-dimensional electron gas (2DEG). A setting of the radiation is provided in such a way that the solid-state detector (20) is operated separately from the response threshold of the photoconduction section and in a sensitivity range of the potential well section. An examination device (100) is also described, said examination device being configured for an examination of a sample (1) using radiation, more particularly X-ray radiation or proton radiation.</p> |
