The Preshower detector, as part of the CMS endcap electromagnetic calorimeter, is designed to have good spatial resolution to identify the position of incoming photons/electrons in the endcaps. It is based on 4288 silicon sensors, each with active area 61x61 mm^2 segmented into 32 strips with 1.9mm pitch. Its spatial resolution relies upon excellent alignment with the neighbouring detectors,...

Beam conditions and the potential detector damage resulting from
their anomalies have pushed the LHC experiments to build their own
beam monitoring devices. The ATLAS Experiment decided to build two
independent systems based on Chemical Vapor Deposition (CVD)
diamond material.
The ATLAS Beam Conditions Monitor (BCM) consists of two stations
(forward and backward) of detectors each...

The alignment of the CMS Silicon Strips detector can be monitored using its built in Laser Alignment System. The 32 Laser beams in each endcap and the 8 Laser beams connecting the barrel and the endcap regions make it possible to monitor the alignment changes to a precision better than 10 $\mu$m and the measurement of the absolute alignment parameters better than 100 $\mu$m.
For this, 434...

The inner tracker of the ATLAS detector will be replaced at the future upgrade to keep the performance at high luminosity operation. We have been developing super-module concept for the upgrade, based on double-sided silicon strip modules. In the super-module concept, one super-module consists of 12 double-sided modules and one double-sided module has 80 readout ASICs which read 128 strips per...

A front-end application specified integrated circuit (ASIC) is developed with a wide dynamic range to read out the signals from a photo-sensor like a photodiode.
The ASIC consists of a charge sensitive preamplifier, four wave-shaping circuits with different amplification
factors and an analog to digital converter(ADC) of Wilkinson-type.
To realize a wider range, the beed back capacitor of...

The CMS silicon strip tracker is the largest detector of its kind. It is expected to operate at the LHC for more than 10 years.
In order to quantify aging effects, it is important to keep track of the evolution of fundamental detector properties under radiation and thermal fluctuations. In the this talk we present our methods measuring the evolution of our sensors full depletion voltage and...

Hadronic tau decays play a crucial role in taking Standard Model measurements as well as in the search for physics beyond the Standard Model. However, hadronic tau decays are difficult to identify and trigger on due to their resemblance to QCD jets. Given the large production cross section of QCD processes, designing and operating a trigger system with the capability to efficiently select...

The punch-through effect is being developed as a way to safeguard against damage to silicon detectors, when a beam loss collapses the field in the sensors and brings the readout implants close to the bias voltage.
We evaluate the efficiency of the punch-through protection (PTP) by flooding the sensors with IR radiation, and measure the voltages on the strips on the readout side, which are...

In the last decade, indirect digital X-ray imaging detectors have widely been used for medical imaging and industrial applications. Indirect-detection method is usually cosisted of a scintillation screen (or an X-ray converter) and 2D electronic image devices. A variety of scintillation materials such as terbium-doped gadolinium oxysulfide (Gd2O2S:Tb) and europium-doped gadolinium...

A new type of pixel sensors, n-in-p type, is being developed in order to cope with the particle fluence of 1-3x10^16 1-MeV neutron-equivalent particles/cm^2 in the LHC upgrade (HL-LHC). The n-in-p pixel sensors are ones for the present front-end chip (FE-I3) of the ATLAS detector and the others for the new front-end chip (FE-I4) for the higher occupancy in the HL-LHC. They are made in a p-bulk...

The silicon pixel and strip sensors are required to work up to
the fluences of $¥geq$1$¥times$10$^{16}$ n/cm2 and
$¥geq$1$¥times$10$^{15}$n/cm2, respectively, for the high luminosity
upgrade of the LHC (HL-LHC). This requires a high sensor bias voltage of
1000 V applicable to cope with the radiation damage in the silicon bulk.
For planar sensors, the distance to the edge and multiple...

The SOI layer is 40-nm silicon, where
readout electronics is implemented.
There is a buried oxide layer between these silicon layers.
This structure is ideal for...

Because direct band gap and high atom number, Cadmium Telluride based detectors are promissing for next generation of radiodiagnostic devices. In present manufacturing technology, the compensation of deep levels is not satisfactory solid. Presence of deep levels leeds to charge tramping in detectors bulk. The effect of charge tramping is inferior charge collection in contacts area and...
