Transition-Edge Sensors for Particle Induced X-ray Emission Measurements

2013

In this paper we present a new measurement setup, where a transitionedge sensor detector array is used to detect X-rays in particle induced X-ray emission measurements with a 2 MeV proton beam. Transition-edge sensors offer orders of magnitude improvement in energy resolution compared to conventional silicon or germanium detectors, making it possible to recognize spectral lines in materials analysis that have previously been impossible to resolve, and to get chemical information from the elements. Our sensors are cooled to the operation temperature (65 mK) with a cryogen-free adiabatic demagnetization refrigerator, which houses a specially designed X-ray snout that has a vacuum tight window…

Development and applications of transition-edge sensors

2015

This thesis focuses on the theory, development and applications of Transition- Edge Sensor (TES) arrays. The main results are the design and development of a fabrication process for a 256 pixel X-ray TES detector with a novel geometry and the development of a measurement setup for TES detectors used in elemental analysis with Particle Induced X-ray Emission (PIXE) measurements. In the early stages of this thesis we fabricated a small scale 32 pixel TES array, but for an actual application purposes the pixel count and the consistency of the fabrication needs to be higher. The cleanroom facilities in the Nanoscience Center are well suited for basic research but they are not suitable for a waf…
