A multichannel detector designed for single minimum ionising particle detection using a stack of sapphire plates is presented.
The performance of the detector was studied in a 5 GeV electron beam at DESY-II. The detector was operated together
with the EUDET beam telescope, which allowed the reconstruction of the position of the impact point at the detector. For each sapphire
plate the...

Instrumentation near the beam-pipe requires extremely radiation hard
sensors. Inside CMS two rings instrumented with 12 single crystal diamond sensors each are installed on both sides of the interaction point. The sensors are subdivided in two pads, and each pad is read out by a dedicated fast radiation hard ASIC in 130 nm CMOS technology.
Due to the excellent time resolution collision...

The Belle-II experiment at the SuperKEKB collider in Japan will operate at
a luminosity approximately 50 times greater than its predecessor (Belle). At
its heart lies a six-layer vertex detector comprising two layers of pixelated
silicon detectors (PXD) and four layers of double-sided silicon microstrip
detectors (SVD). One of the key measurements for Belle-II is time-dependent

A vertex detector is under development for CLIC, a future linear electronโpositron collider with a maximum centre of mass energy of 3 TeV. In order to perform precision physics measurements in a challenging environment, the CLIC vertex detector must have excellent spatial resolution, full geometrical coverage extending to low polar angles, extremely low mass, low occupancy facilitated by...

Transient Current Technique (TCT) is one of the important methods to characterize Silicon (Si) detectors and is based on the time evolution of the charge carriers generated when a laser light is shone on it. For red laser, charge is injected only to a small distance from the surface of the detector. For such a system, one of the charge carriers is collected faster than the readout time of the...

Future experiments at the European X-Ray Free Electron Laser (XFEL) will require silicon pixel sensors with demanding performance: a wide dynamic range from 1 up to 10^4 12-keV photons per pixel, a small pixel pitch (~100 ฮผm), minimum dead area and a radiation tolerance of 1GGy per 3 years of operation. Therefore, the development of four-side buttable tile detectors that meet such requirements...

Silicon-based sensors are well established as tracking devices in modern particle detectors. The high spatial resolution and the comparable low costs make them best suited for large scale applications like the CMS Tracker. However, the required quantities often exceed the capabilities of academic institutions and therefore commercial vendors are assigned with the production. Since 2009 the...

The sensor electronics are entirely placed inside the n-well which is at the same time used as the charge collection electrode. High voltage is used to deplete the part of the substrate around the n-well.

In wide bandgap semiconductors the high resistivity is often achieved...
