In this paper we report on the timing resolution of first production 50 micro-meter thick Ultra-Fast Silicon Detectors (UFSD) as obtained in a beam test with pions 180 GeV/c momentum. UFSD are based Low-Gain Avalanche (LGAD) design, employing n-on-p silicon sensors internal charge multiplication due to presence thin, low-resistivity diffusion layer below junction. The used belongs thin (50 μm) sensors, an pad area 1.4 mm2. gain was measured vary between 5 and 70 depending bias voltage....
In this contribution we will review the progresses toward construction of a tracking system able to measure passage charged particles with combined precision ∼10 ps and μm, either using single type sensor, concurrently position time, or combination time sensors.
Is it possible to design a detector able concurrently measure time and position with high precision? This question is at the root of research development silicon sensors presented in this contribution. Silicon are most common type particle detectors used for charged tracking, however their rather poor resolution limits use as precise timing detectors. A few years ago we have picked up gantlet enhancing remarkable capability. I will be presenting our results following pages.
We review the progress toward development of a novel type silicon detectors suited for tracking with picosecond timing resolution, so called Ultra-Fast Silicon Detectors. The goal is to create new family particle merging excellent position and resolution GHz counting capabilities, very low material budget, radiation resistance, fine granularity, power, insensitivity magnetic field, affordability. aim achieve concurrent precisions ∼ 10 ps μm 50 thick sensor. Detectors are based on concept...
The CMS-TOTEM Precision Proton Spectrometer (CT-PPS) detector will be installed in Roman pots (RP) positioned on either side of CMS, at about 210 m from the interaction point. This measure leading protons, allowing detailed studies diffractive physics and central exclusive production standard LHC running conditions. An essential component CT-PPS apparatus is tracking system, which consists two stations per arm equipped with six 3D silicon pixel-sensor modules, each read out by PSI46dig...
The Ultra Fast Silicon Detectors (UFSD) are a novel concept of silicon detectors based on the Low Gain Avalanche Diode (LGAD) technology, which able to obtain time resolution order few tens picoseconds. First prototypes with different geometries (pads/pixels/strips), thickness (300 and 50 μm) gain (between 5 20) have been recently designed manufactured by CNM (Centro Nacional de Microelectrónica, Barcelona) FBK (Fondazione Bruno Kessler, Trento). Several measurements these devices performed...
The development of Low-Gain Avalanche Diodes (LGADs) has made possible to manufacture silicon detectors with output signals that are about a factor 10 larger than those traditional sensors.This increased brings many benefits such as the possibility developing thin large enough signals, good immunity towards low charge collection efficiency and it is key for excellent timing capabilities.In this paper, we report on sensors based LGAD design optimized achieve performance, so-called Ultra-Fast...
The Large Hadron Collider will undergo a luminosity upgrade targeting peak instantaneous ranging from 5 up to 7.5$\times10^{34}$\,cm$^{-2}$s$^{-1}$. ambitious goal of the High Luminosity LHC is achieve total 3000--4000\,fb$^{-1}$ proton-proton collisions at center-of-mass energy 14\,TeV. To cope with such challenging environmental conditions, outer tracker CMS experiment be upgraded using closely spaced silicon sensors (pixels and strips) provide tracking information Level-1 trigger.

Based on curvature representation, a fuzzy Kohonen self-organizing feature mapping is combined with the delta rule to recognize partially occluded objects. Because of learning and tolerant performance as well membership function, hybrid neural networks can objects higher precision.
