The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). A new timing detector in CMS will measure minimum ionizing particles (MIPs) with a time resolution of 30-40 ps for MIP signals at a rate of 2.5 Mhit/s per channel at the beginning of...
The High-Luminosity Large Hadron Collider (HL-LHC) project aims to boost the performance of the LHC in order to increase the potential for discoveries for LHC Run-4 and onwards. The upgrade aims at increasing the instantaneous luminosity of the machine. In order to cope with the expected increase of both radiation and rates, the electronics that host the first level of readout and trigger...
The Gas Electron Multiplier (GEM) Detector is being used extensively to handle a fairly large flux environment in high energy and other related experiments. Due to the ease of operation with environment friendly gases, this detector can be deployed to wider range of experiments as well as in applications to developing the instruments for humanitarian aid purposes. In this talk, we will present...
The LHCb detector is undergoing a comprehensive upgrade for data taking in the LHC's Run 3, which is scheduled to begin in 2022. The increased data rate in Run 3 poses significant data-processing and handling challenges for the LHCb experiment. The offline computing and dataflow model is consequently also being upgraded to cope with the factor 30 increase in data volume and associated demands...
The aim of the LHCb Upgrade II is to operate at a luminosity in the range of 1 to 2 x 10$^{34}$ cm$^{-2}$ s$^{-1}$ to collect a data set of 300 fb$^{-1}$. This will require a substantial modification of the current LHCb ECAL due to high radiation doses in the central region and increased particle densities. The ECAL has to provide good energy and position resolutions in these conditions....
The next generation of collider detectors will make full use of Particle Flow algorithms, requiring high precision tracking and full imaging calorimeters. The latter, thanks to granularity improvements by 2 to 3 orders of magnitude compared to existing devices, have been developed during the past 15 years by the CALICE collaboration and are now reaching maturity. The state-of-the-art status...
The intelligent Data Delivery Service (iDDS) has been developed to cope with the huge increase of computing and storage resource usage in the coming LHC data taking. It has been designed to intelligently orchestrate workflow and data management systems, decoupling data pre-processing, delivery, and main processing in various workflows. It is an experiment-agnostic service that has been...
A major worldwide effort is underway to procure the radiopure argon needed for DarkSide-20k (DS-20k), the first large scale detector of the new Global Argon Dark Matter Collaboration. The Urania project will extract and purify underground argon (UAr) from CO2 wells in the USA at a production rate of about 300 kg/day. Additional chemical purification of the UAr will be required prior to its use...
Detectors at future e+e- colliders need special calorimeters in the very forward region for a fast estimate and precise measurement of the luminosity, to improve the hermeticity and mask the central tracking detectors from backscattered particles. In our concept, two compact calorimeters are foreseen, LumiCal and BeamCal. Both are designed as sandwich calorimeters with very thin sensor planes...
The muon campus program at Fermilab includes the Mu2e experiment that will search for a charged-lepton flavor violating processes where a negative muon converts into an electron in the field of an aluminum nucleus, improving by four orders of magnitude the search sensitivity reached so far.
Mu2e’s Trigger and Data Acquisition System (TDAQ) uses {\it otsdaq} solution. Developed at Fermilab,...
The COMET Phase-I experiment aims to search for charged lepton flavour violation in the coherent neutrino-less conversion of a muon to an electron with a 100 times better sensitivity than the current best limit. Muons required for the search are generated from the in-flight decay of low momentum pions produced inside a target by impinging a powerful proton beam extracted from the J-PARC Main...
The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L ~ 7.5 × 10$^{34}$ cm$^{-2}s^{-1}$ will have a severe impact on the ATLAS detector reconstruction and trigger performance.
The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected....
A precise measurement of the luminosity is a key component of the ATLAS physics programme. ATLAS uses several detectors and algorithms to determine the luminosity. The absolute calibration of these algorithms is carried out in LHC runs with special beam conditions at low luminosity. The track counting luminosity measurement is used to determine the calibration transfer from the low-luminosity...
The ATLAS experiment is currently upgrading the first muon station in the high-rapidity region with the construction of new detector structures, named New Small Wheels (NSW), based on large-size multi-gap resistive strips Micromegas technology and small-strip Thin Gap Chambers (sTGC).
The first of the two NSW (NSW-A) has been fully commissioned and installed in the ATLAS underground cavern...
The ATLAS experiment at the LHC can record about 3 kHz of physics collisions, out of an LHC design bunch crossing rate of 40 MHz. A two-level trigger system is used to achieve a high selection efficiency for rare physics events while reducing the significant background rate. The event selection is based on physics signatures, such as the presence of energetic leptons, photons, jets or missing...
FASER, or the Forward Search Experiment, is a new experiment at CERN designed to complement the LHC's ongoing physics programme, extending its discovery potential to light and weakly-interacting particles that may be produced copiously at the LHC in the far-forward region. New physics particles targeted by FASER, such as long-lived dark photons or dark scalars, are characterised by a signature...
Modern physics experiments usually rely on very big experimental setup where it is possible to find a wide variety of detectors: silicon microstrip trackers, plastic scintillator calorimeters, LAr cryostats readout by a Time Projection Chamber, spectrometers composed of several drift tubes and resistive plate chambers. Moreover, other large and medium scale setups for the search of neutrinos...
With the end of RUN-II, the LHC has delivered only 4% of the collision data expected to be available during its lifetime. The next data-taking campaign -- RUN-III -- will double the integrated luminosity the LHC accumulated in 10 years of operation. The Run-III will be the herald of the HL-LHC era, an era when 90% of total LHC integrated luminosity (4 ab−1) will be accumulated allowing ATLAS...
In 2022 the upgraded LHCb experiment will use a triggerless readout system collecting data at an event rate of 30 MHz. A software-only High Level Trigger will enable unprecedented flexibility for trigger selections. During the first stage (HLT1), a sub-set of the full offline track reconstruction for charged particles is run to select particles of interest. After this first stage, the event...
he Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). To sustain the harsh conditions foreseen in Phase II the CMS experiment has designed a novel endcap calorimeter that uses approx. 5.8M radiation-tolerant Silicon sensors. These sensors...
Searches for long-lived particles are among the most promising search channels for physics beyond the Standard Model (BSM) at the LHC.
One strategy relies on reconstructing the decay products of potential neutral BSM particles decaying within the tracking detector volume. To maximise the sensitivity of such efforts, charged particle tracks need to be reconstructed even if their trajectories...
The Large Hadron Collider (LHC) will be upgraded in several phases to significantly expand its physics program. After the current long shutdown from 2018-2021 (LS2) the accelerator luminosity will be increased to 2 − 3 * 10^34cm−2s−1 exceeding the design value of 1 * 10^34cm−2s−1 allowing the CMS experiment to collect approximately 100 fb−1/year. A subsequent upgrade will increase the...
Prototypes of electromagnetic and hadronic imaging calorimeters developed and operated by the CALICE collaboration provide an unprecedented wealth of highly granular data of hadronic showers for a variety of active sensor elements and different absorber materials. In this presentation, we discuss detailed measurements of the spatial and the time structure of hadronic showers to characterise...
The physics aims at future lepton colliders such as CLIC or FCC-ee pose challenging demands on the performance of the proposed all-silicon vertex and tracking-detector systems. A single-plane spatial resolution of a few micrometers is needed, combined with a low mass of ~0.2% X0 per layer for the vertex detectors and ~1% X0 per layer for the main trackers. Moreover, hit-time tagging with a few...
The Silicon photomultipliers are extensively studied at room temperatures whereas only a limited research has been done on them at cryogenic temperatures. The recent R&D for underground low energy particle physics experiments involve SiPMs extensively as the prime photo-detectors due to their ability to enhance the sensitivity of the rare particle events. For cryogenic applications, the SiPMs...
The “muon-to-electron conversion” (Mu2e) experiment at Fermilab will search for the Charged Lepton Flavour Violating neutrino-less coherent conversion of a muon into an electron in the field of an aluminum nucleus. The observation of this process would be the unambiguous evidence of physics beyond the Standard Model. Mu2e detectors comprise a straw-tracker, an electromagnetic calorimeter and...
Plastic scintillator detectors are widely used in high-energy physics, often as an active neutrino target, both in long and short baseline neutrino oscillation experiments. They can provide 3D tracking with $4\pi$ coverage and calorimetry of the neutrino interaction final state combined with very good particle identification capabilities and sub-nanosecond time resolution. Moreover, the large...
Machine learning enjoys widespread success in High Energy Physics (HEP) analyses at LHC. However the ambitious HL-LHC program will require much more computing resources in the next two decades. Quantum computing may offer speed-up for HEP physics analyses at HL-LHC, and can be a new computational paradigm for big data analyses in High Energy Physics.
We have successfully employed three...
Software tools are foundational for the
development of future collider experiments. Detector optimization and
physics performance studies crucially depend on the availability of
