Seminar: Commissioning of the CASCADE detector at MIRA

The Cascade-Detector is a new type of thermal neutron detector. It offers a solution to using solid neutron converters with several layers but maintaining the information on the position of the neutron. The new concept provides high efficiency, a broad solid angle and good spatial resolution by the use of so-called GEM-foils. These are “Gas Electron-Multiplier”-foils, which are substrates with a special microstructure coated with the solid neutron converter. The microstructure produces an electric field, which allows the use of several foils after each other without losing the position information.
The characterization of the CASCADE detector at MIRA is the topic of my current bachelor thesis. I will present the actual state of my work. Starting with the basics of neutron detection I will then give an overview of different types of neutron detectors. Showing how these concepts are used in the CASCADE-Detector, followed by the results of my measurements and the conclusions, which can be drawn from them.
