Wine and cheese poster and industry session
We successfully demonstrated simple and low cost 2.5 Gb/s optical wireless transmission at 10 cm distance, aiming to be employed in high-energy physics experiments using off-the-shelf VCSEL and PIN photodiode with proper ball lens. The measured tolerance to misalignment is around ±1mm at Bit Error Rate of 10-12.
Summary:
Particle physics experiments generate large amounts of data, whose...
Several efforts have been recently devoted to develop high-resolution timing detectors for tracking at the High Luminosity LHC (HL-LHC) experiments while track triggers, implemented with dedicated hardware, have been used at hadron colliders to select heavy-flavour decays. We propose a R&D project to combine the two methods and develop an innovative detector, based on accurate time and...
The Belle II experiment at SuperKEKB is rapidly approaching its data taking phase, where it will be used to perform precision measurements of SM and new physics processes with unprecedented accuracy. At the same time, the Belle dataset (~1ab^{-1}) still presents rich possibilities for physics analyses, which can now also be performed within the Belle II Analysis Software Framework (basf2). In...
The HL-LHC accelerator will constitute a new frontier for particle physics after year 2024. Major experimental challenge resides in inner tracking detectors: here the dimension of sensitive area (pixel) has to be scaled down with respect to LHC detectors.
This paper describes a readout ASIC in 65nm CMOS with a matrix of 64x64 pixels each of dimension 50x50 μm2, designed by CHIPIX65 project,...
The AEGIS experiment at CERN aim to measure the gravitational constant of anti-Hydrogen and in the future perform long-term anti-matter mass spectroscopy. To achieve the gravitational measurement, the AEGIS collaboration will produce a pulsed anti-Hydrogen beam for the first time and measure the deflection of the path of the antihydrogen from a straight line, after it has passed through a...
The AM06 is the 6th version of a large Associative Memory chip designed in 65 nm CMOS technology. The AM06 operates as a highly parallel ASIC processor for pattern recognition in ATLAS experiment at CERN. It is the core of the Fast TracKer electronic system which is tailored for online track finding in trigger system of ATLAS experiment at the LHC. The Fast TracKer system is able to process...
Radiation detectors built in high-voltage and high-resistivity CMOS technology are an interesting option for the large area pixel-trackers sought for the upgrade of the Large Hadron Collider experiments. A possible architecture is a hybrid design, where CMOS sensors are readout by front-electronics coupled through a thin dielectric layer. A critical requirement is the radiation hardness of...
Production of 60 AC-coupled double-sided silicon microstrip sensors, designed to equip the two layers of the HERD detector in the Limadou-CSES project, has been recently completed at FBK. The sensors, fabricated on 150 mm silicon wafers, have an overall size of 10.96 cm x 7.76 cm = 85.05 cm2.
Sensor testing and quality control has been performed at INFN Trieste and TIFPA. After presenting an...
A fast hardware based track trigger for high luminosity upgrade of the Large Hadron Collider (HL- LHC) is being developed in ATLAS. The goal is to achieve trigger levels in high pileup collisions that are similar or even better than those achieved at low pile-up running of LHC by adding tracking information to the ATLAS hardware trigger which is currently based on information from calorimeters...
Pixels detectors are widely used detection devices in high-energy physics experiments. For more precise and accurate measurements one would like to have faster, less noisy and smaller pixels, but current technology imposes several limits on these characteristics.
The aim of this study is to explore the applications of bi-dimensional materials such as graphene or transition metal...
Planar hybrid silicon sensors are a well proven technology for past and current particle tracking detectors in HEP experiments. However, the future high-luminosity upgrades of the inner trackers at the LHC experiments pose big challenges to the detectors. A first challenge is an expected radiation damage level of $2\cdot 10^{16}\, \mbox{n}_{\mbox{eq}}/\mbox{cm}^2$. For planar sensors, one way...
The Belle-II experiment is a multipurpose particle detector which will
take data at the asymmetric electron positron collider SuperKEKB
operated at a design luminosity of $8\times 10^{35} cm^{-2} s^{-1}$.
Track reconstruction close to the interaction point in the Belle-II
experiment is provided by the Silicon Vertex Detector (SVD), consisting of
4 layers of double sided silicon...
A readout channel for applications to X-ray diffraction imaging at free electron lasers has been developed in a 65 nm CMOS technology. The analog front-end circuit can achieve an input dynamic range of 100 dB by leveraging a novel signal compression technique based on the non-linear features of MOS capacitors. Trapezoidal shaping is accomplished through a transconductor and a switched...
To withstand the higher rates of LHC Runs 2 and 3, with expected luminosities of up to 2 x 10^34 cm^{-2} s^{-1}, the current CMS pixel detector at the LHC will be replaced as part of the CMS Phase I Upgrade during the extended winter shutdown in 2016/17. The new pixel detector features a new geometry with one additional detector layer in the barrel region (BPIX) and one additional disk in the...
The Outer Tracker upgrade of CMS introduces new challenges for the front-end readout electronics. In particular, the capability of identifying particles with high transverse momentum requires high speed real time communication among readout ASICs. The Pixel-Strip module needs two different readout ASICs, namely the SSA for the strip sensor and the MPA for the pixelated sensor. At each Bunch...
The INFN-Retina project aims at developing a fast track finding system prototype capable to operate at 40 MHz event rate with hundreds of track per event, for the high-luminosity LHC experiments. A tracking system prototype to be tested on beam has been built as practical demonstrator. In this work, we present the testbeam results of an embedded tracking system prototype based on artificial...
The Pixel Luminosity Telescope is one of the newest additions to a number of sub-detectors dedicated to measuring the luminosity provided to the CMS experiment by the LHC. The PLT, as an independent luminometer, consists of eight 3-layer telescopes based on silicon pixel detectors placed at a high eta around the beam pipe on each end of CMS. All 16 telescopes view the interaction point under a...
The Belle-II VerteX Detector (VXD) is a 6 layers silicon tracker device that will cope with an unprecedented luminosity of 8 × 10^35 cm−2s−1 achievable by the new SuperKEKB e+e− collider, now under commissioning at the KEK laboratory (Tsukuba, Japan).
All environment parameters such as temperature, humidity and radiation levels, must be constanly monitored and under certain conditions...

The instantaneous luminosity of the LHC is expected to increase at HL-LHC so that the amount of pile-up can reach a level of 200 interaction per bunch crossing, almost a factor of 10 w.r.t the luminosity reached at the end of run 1. In addition, the experiments plan a 10-fold increase of the readout rate. This will be a challenge for the ATLAS and CMS experiments, in particular for the...
The vertex detector (VXD) for the Belle-II experiment, at the Super-KEKB in Japan, measures precisely information of vertexing and tracking. The VXD consists of a pixel detector (PXD) and a silicon vertex detector (SVD) with two and four layers, respectively, so that operates under a high luminosity environment of the Belle-II experiment. For the SVD, a novel chip-on-sensor concept, called...
