Silicon radiation detectors with minimum dead area in the sensor periphery are desirable and sometimes necessary for many applications in nuclear medicine, high energy physics, and X–ray science. The dead area typically includes a guard ring structure that is required for facilitating a uniform elec...

In preparation for operation at the High Luminosity LHC, the tracking system of the ATLAS experiment is replaced with a new inner tracker, the ITk. The innermost layers of this system must be designed to withstand a fluence of more than 10^16 cm-2 1 MeV neutron equivalents. At SINTEF, Norway, silico...

The upcoming High Luminosity LHC (HL-LHC) puts stringent requirements on the tracking detectors situated closest to the interaction point in the planned Inner Tracker (ITk) of the ATLAS experiment. 3D pixel detectors have been proposed as a candidate for the innermost layers of the ITk since these d...

Detectors with high radiation tolerance and high time resolution are required for charged particle in high physics and space applications. 3D detectors were introduced by S. Parker 1 in the middle 90’ and they represented a starting point for evolved device able to work at fluency up to 2 × 10^...

Minimisation of insensitive volume in silicon sensors is highly demanded in many applications for high energy physics, structural biology, synchrotron experiments and nuclear medicine. A large contribution to this insensitive volume is the guard rings and current terminating structures required in c...

Silicon radiation sensors typically have an inactive volume at the device periphery necessary to accommodate multiple guard-rings and current terminating structures necessary to deliver increased breakdown voltage and stability and to shield the active area from the defects induced by the dicing pro...

The responses of two silicon on insulator (SOI) 3-D microdosimeters developed by the Centre for Medical Radiation Physics were investigated with a range of different low energy ions, with high linear energy transfer (LET). The two microdosimeters n-SOI and p-SOI were able to measure the LET of diffe...

Due to radiation hardness requirements, 3D detectors are the best candidate technology for the innermost tracking layers at the High Luminosity LHC (HL-LHC) as well as for radiation monitoring in long space missions. In the framework of the project "Three-dimensional Low-Voltage Silicon Detecto...

In the course of this research, a radiation damage study of 3D microdosimeter structures were carried out using 5.5 MeV He2+ and 24 MeV C-12 ions microbeam. Radiation damage study post irradiation of the microdosimeters with low energy Li, C, O, ti ion was also investigated. Additionally, electrical...
