Among the new emerging cancer therapies, Microbeam Radiation Therapy (MRT) is currently showing very promising results in terms of limiting or decreasing tumor growth while keeping the damage to healthy tissue to a minimum. The MRT is able to deliver unprecedented dose rates of up to 20 kGy/s, posing important questions in terms of treatment planning and patient safety during treatment. For this reason,...
The Micro-Beam Radiation Therapy (MRT) is a promising newly emerged cancer treatment currently under development at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. Several safety requirements must be complied with, prior to the human clinical trials of the MRT such as the ability to send a signal to the emergency beam shutter in case of any beam anomalies, in order to avoid...
3D active edge sensors have advantages such as radiation hardness and edgeless capability. With the use of deep reactive ion etching and wafer bonding, 18.5 by 20.5 mm2 3D detectors with active edges have been successfully fabricated at SINTEF MiNaLab. These sensors are compatible with the ATLAS FE-I4 readout electronics. Fabrication process and difficulties are presented and the preliminary electrical...
3D detectors with electrodes penetrating through the entire silicon substrate have many advantages over conventional planar silicon technology, for example, high radiation tolerance. High aspect ratio through-wafer holes are essential in such fabrication, and deep reactive ion etching (DRIE) is used. A series of DRIE processes were tested and optimised to achieve the required aspect ratio, and in...
