The enhanced lateral drift (ELAD) sensor concept seeks to improve the position resolution by increasing the lateral size of the charge distribution already during the drift in the sensor material. The ELAD sensor design has been optimised using SYNOPSYS TCAD tool. The geometry of the buried implants, their doping concentration and the position inside the sensor were optimised for different...
Proton therapy is, due to its higher precision of energy deposition, an effective
alternative to conventional x-ray therapy. Occurring uncertainties due to the use
of x-ray computed tomography in treatment planning can be reduced through
the use of proton computed tomography. To accurately predict the range of the
protons in tissue, it is necessary to reconstruct the tracks of the protons...
The ATLAS-TPX detector is a telescope made of two Timepix ASICs with silicon sensors facing each other. A network of 16 such detectors was installed in ATLAS during Run 2 (2015-2018) for characterizing the radiation environment. In order to measure charged particle fluences several effects had to be assessed, such as the performance of tracking algorithms, the impact of delta-rays or the...
A prototype of a digital pixel electromagnetic calorimeter, EPICAL-2, has been designed and constructed. It consists of alternating W absorber and Si sensor layers, with a total thickness of ~20 radiation lengths and an area of 30 mm x 30 mm. The design is the next step in pixel calorimetry, following up on a previous prototype using MIMOSA sensors [1]. The new EPICAL-2 detector employs the...
Monolithic CMOS silicon sensors with a small collection diode are characterised by a low input capacitance that allows for a reduction of power consumption, a lower detection threshold and an increase in signal/noise ratio. However, the small collection diode design gives rise to non-uniform field configurations that are challenging to simulate and model, requiring an advanced simulation...
The dual-sided microstructured semiconductor neutron detectors (DSMSND) provide a much higher neutron detection efficiency as compared to a coated planar semiconductor device. This is achieved by alternatively staggering 6LiF-filled trenches between the top and bottom surface of a microstructured silicon diode. This design restricts neutron streaming paths and generates a more complex...
Production of antihydrogen and its detection through annihilation are the basis of most of the precision experiments at the Antiproton Decelerator at CERN, which makes the antiproton-nucleus annihilation at rest one of the key processes. Monte Carlo simulations are mostly performed with the physics models included in Geant4, such as CHIPS and Fritiof (FTF), and recently also with FLUKA....
Silicon sensors featuring a hexagonal pixel pattern benefit from an accelerated charge collection in the pixel corners and reduced charge sharing due to fewer neighbouring pixel cells, which has the potential to improve time resolution and efficiency. The detector models commonly used in Allpix Squared assume rectangular pixel cells and cannot be used for devices with a hexagonal grid. To...
