Polycrystalline CVD (pcCVD) diamond is an attractive detector material for harsh radiation environments because of its radiation tolerance, fast signal formation, low leakage current, and availability in large areas. Its signal response is, however, degraded by charge trapping associated with defects and grain boundaries, leading to reduced charge collection and distorted transient signals. We...

The development of high-resolution radiation detectors is essential for accurate and quantitative imaging in fields such as medical imaging, non-destructive testing, and high-energy physics. Small-pixel semiconductor detectors, like CdTe and CZT, show great promise. However, as pixel sizes reach below 300 µm, issues such as charge sharing and charge loss emerge, compromising data integrity....

In radiotherapy for cancer treatment, proton therapy is an important treatment due to the steep dose gradient, which leads to a high conformal dose distribution while sparing healthy tissue. However, anatomical changes of the patient have a high impact on the range of the protons; this uncertainty leads to larger safety margins.
