Characterization of the X-ray spectrum of a linear accelerator



In this paper, we present the development of a numerical model to determine the energy spectrum from an attenuation curve via transmission measurements which combines two types of inverse models: a continue model and a discrete model. We validate this tool using a test spectrum and its transmission curve obtained via Monte-Carlo simulation. This qualification allowed us to determine its sensitivity (signal-to-noise ratio, SNR) in order to have a good convergence. We show that if the SNR is less than 4%, we have a good estimation of the photon energy spectrum. Then, it was experimentally tested with a transmiss ...

IPM Workshop Diamond Magnetometry: a Quantum Sensing Technique


Diamond magnetometry is a quantum sensing technique which allows nanoscale MRI. It is based on a defect in diamond, the so-called NV center, which changes its optical properties based on its magnetic surrounding. Since optical signals can be read out more sensitively, this technique offers unprecedented sensitivity. We will first give a general overview over different modes of diamond magnetometry and discuss advantages and drawbacks.
In the second lecture we will focus on relaxometry, a specific mode of diamond magnetometry and how we use this technique to answer biological questions. More specifically, relaxometry is sensitive to ma ...
