In the last year the CMS experiment has constructed and integrated the largest
ever build full silicon strip tracker. Therefore the CMS tracker collaboration
set up a unique scheme of quality control to ensure the necessary high quality
of all of the 15,148 modules and their super structures. The applied scheme
of quality control revealed several problems, which escaped the initial R&D...

The Semiconductor Tracker(SCT) of the ATLAS detector enters the last
phase of installation and commissioning at CERN. Prior to inserting into
ATLAS, the barrel part of the SCT has been integrated with the Transition
Radiation Tracker (TRT) barrel and tested with cosmic rays. A sector of 468
SCT modules has been powered and read simultaneously with TRT modules
in physics mode. In...

The CDF silicon vertex detector is one of the largest operating silicon
detectors in particle physics. Its silicon sensors have 722,432 channels read
out by 5,456 chips and cover an area of 6 m 2. The detector is used for
precision tracking and in the hardware trigger for events with a displaced
vertex. It is very important for a success of the CDF physics program. The
silicon...

Carbon Nanotubes are one-dimensional structures with diameters ranging
between 2 and 100 nm and lengths up to hundreds of microns. They are
characterized by a large variety of peculiar characteristics such as a
semiconductive or metallic behaviour, a ballistic electrical conductivity and
enhanced field emission capabilities. Among these characteristics their
sensitivity to the...

The need for ultra-radiation hard semiconductor detectors for the tracker
regions in high energy physics experiments at a future high luminosity
hadron collider like the LHC Upgrade has led to the formation of the CERN
RD50 collaboration. The R&D directions of RD50 follow two paths:
understanding radiation effects, and finding mitigation through the use of
new materials, device...

In view of the projected luminosity upgrade of the LHC, we are studying
novel Silicon detectors in terms of their radiation-hardness to be employed
as tracking detectors at the sLHC. We have tested 3D-detectors of
singletype-column (STC) design, with only n-type columns etched into a p-
type substrate. Rows of the columns are connected together to form strips.
Using ATLAS SCT...

CMOS sensors are being developed for various position sensitive detectors
requiring high granularity and low material budget, together with relatively
fast read-out and good radiation tolerance as well as low power dissipation. A
review of the charged particle detection performances achieved with sensors
of the MIMOSA series will be provided, emphasizing preliminary test results
of...

Silicon Drift Detectors (SDDs) are X-ray detectors with the outstanding
performance for the measurement of the kaonic atom X-ray lines. The
measurement of the kaonic hydrogen/deuterium X-rays with a high
background suppression is a crucial issue, because of the small X-ray yields
(a few % in kaonic hydrogen and much smaller in kaonic deuterium) and
high background usually...

The effort to develop a monolithic pixel sensor based on the SOI (silicon
on insulator) CMOS technology is presented. In SOI, MOS transistors are
produced on silicon oxide layer (BOX) above a silicon substrate. A monolithic
pixel detector is realized if we adopt a high-resistivity silicon and p-type and
n-type implantations can be made in the substrate. The charge induced in the...
