A muon collider could provide scattering at the multi-TeV centre of mass energy characteristic of a hadron-hadron machine in the clean experimental environment typical of an electron-positron one, allowing for a consolidation of the present knowledge of the Standard Model and for the search of new physics. The Low EMittance Muon Accelerator (LEMMA) scheme has been recently proposed: low...

In the last 10 years, the UA9 collaboration has used the H8 line in the North Area of the CERN SPS; the aim of the tests was to investigate coherent interaction physics of charged particles with bent crystals and to characterize their properties and performance for application in circular accelerators (SPS and LHC).

The Analogue Hadron Calorimeter (AHCAL) developed by the CALICE collaboration is a scalable engineering prototype for a Linear Collider detector. It is a sampling calorimeter of steel absorber plates and 3$*$3 cm$^2$ plastic scintillator tiles read out by silicon photomultipliers (SiPMs) as active material (SiPM-on-tile). The front-end chips are integrated into the active layers of the...

As part of the HL-LHC detector upgrade programme, the CMS experiment is developing a High Granularity Calorimeter (HGCAL) to replace the existing endcap calorimeters. The HGCAL will be realised as a sampling calorimeter, including 36 layers of silicon pads and 14 layers combining both silicon and scintillator detectors interspersed with metal absorber plates. Prototype modules based on 6-inch...

LHC Run-II finished at the end of 2018 after operating since 2015. During this time the electromagnetic calorimeter (ECAL) of the Compact Muon Solenoid (CMS) has been performing tremendously under very challenging conditions at a center-of-mass energy of 13 TeV and a bunch-spacing of 25 ns. The environment will be even more challenging for the ECAL after the the High-Luminosity upgrade of the...

The Large Hadron Collider (LHC) Phase II upgrade aims to increase the accelerator instantaneous luminosity by a factor of 10. Due to the expected higher radiation levels, aging of the current electronics and to provide the capability of coping with longer latencies of up to 35 µs needed by the trigger system at such high pileup levels, a new readout system of the ATLAS Tile Calorimeter...

By winning the international contest Beamline for Schools, we, a team of six high school students, got the opportunity to conduct our own experiment at the DESY II Test Beam Facility in October 2019. In the experiment we searched for a difference between the electron and positron, concerning the development of electromagnetic particle showers. To measure the spatial evolution of particle...

The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L ≃ 7.5×1034 cm−2 s-1 will have a severe impact on the ATLAS detector performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing. The reconstruction and trigger performance for electrons, photons as well as jets and transverse...

Over the past decade, proton and ion-beam therapy has become an established form of cancer treatment. Currently, the achievable precision of this therapy is limited by uncertainties due to treatment planning based on conventional photon imaging. A significant effort is therefore invested into the development of proton or ion imaging modalities. A typical apparatus for such applications...

Sensors based on ultrapure single crystal CVD diamonds have been operated in the Precision Proton Spectrometer (PPS) of the CMS experiment during the LHC Run 2 (2016-2018). Such sensors were used for the timing system of PPS and were hosted in the Roman Pots (RPs), movable devices allowing to bring the hosted detector inside the LHC beam pipe, at few millimeters from the beams. The sensors...

The operation of the proton linear accelerator for multipurpose application started from 2013 at Korea Multipurpose Accelerator Complex (KOMAC) at Gyeongju, Republic of Korea. They supply two energy of proton beams to users, one for 20 MeV and the other for 100 MeV proton beam for various applications with the energy range from 20 to 100 MeV by degraders.

The High Luminosity upgrade of the CERN Large Hadron Collider (HL-LHC) calls for new high-radiation tolerant silicon pixel sensors, capable of withstanding fluences up to 2.3E16 neq/cm2 (1MeV equivalent neutrons). In this presentation results obtained in beam test experiments with 3D pixel sensors interconnected with the RD53A readout chip are reported. RD53A is the first prototype in 65nm...

Challenging requirements are imposed on the vertex and tracking system of the detector for the proposed future Compact Linear Collider CLIC. A temporal resolution of a few ns and a spatial resolution of a few $\mu $m need to be achieved simultaneously with a material budget of down to less than one percent per detection layer. Various silicon pixel detector technologies are under investigation...

Future experiments in particle physics foresee few-micrometer single-point position resolution in their vertex detectors, motivated by e.g. b-tagging capabilities. Instead of scaling down pitch sizes the so-called enhanced lateral drift (ELAD) sensor concept seeks to improve the position resolution by increasing the lateral size of the charge distribution already during the drift in the sensor...

During the first Long Shutdown (LS1) of the LHC the Insertable B-Layer (IBL) was installed in the ATLAS experiment to improve the tracking performance. It is placed between the existing inner pixel layer and a new beam pipe. Because of the small distance to the interaction point, the planar and 3D sensors of the IBL are exposed to a high flux of ionizing radiation. The planar n$^+$-in-n pixel...

A key point in the design stage of a HEP tracking detector is to minimize the amount of material and therefore radiation lengths (X$_0$) associated with the detector. The values for simple and bare materials are available in tables, but more complex material compounds, such as adhesives or composite materials, are often not directly available and only estimations exist.
The method of...

After the upgrade of the LHC to the HL-LHC, the experiments will need to cope with new, more challenging conditions. The higher luminosity and particle flux of the HL-LHC will cause a higher occupancy and radiation dose. Therefore, a new tracking system for the ATLAS experiment is required: the Inner Tracker (ITk). It will consist of several types of silicon sensors. For the pixel detector...

In order to cope with the occupancy and radiation doses expected at the High-Luminosity LHC accelerator, the ATLAS experiment will replace its Inner Detector with an all-silicon Inner Tracker (ITk), consisting of pixel and strip subsystems. The strip subsystem will be built from modules, consisting of one n+-in-p silicon strip sensor, and one or two PCB hybrids containing the front-end...
