Calorimetry and Particle ID

Oral presentation (onsite or remote - not decided)

The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, using steel as the absorber and plastic scintillators as the active medium. The scintillation light is collected by wavelength-shifting fibres and read out by photomultiplier tubes (PMTs). The analogue signals are amplified, shaped, digitized at 40 MHz and stored on the...

Oral presentation (onsite or remote - not decided)

The Tile Calorimeter (TileCal), the central hadronic calorimeter of the ATLAS experiment at the Large Hadron Collider (LHC), is undergoing a major Phase-II upgrade to meet the challenging requirements of the High-Luminosity LHC (HL-LHC). The upgrade introduces a completely redesigned electronics architecture to cope with trigger rates of up to 1 MHz, increased radiation levels and higher...

Oral presentation (onsite or remote - not decided)

The ATLAS Tile Calorimeter (TileCal) is a sampling hadronic calorimeter in the central region of the ATLAS detector, consisting of steel absorber plates interleaved with plastic scintillator tiles. The High-Luminosity phase of the LHC (HL-LHC), expected to begin in 2030, will deliver an instantaneous luminosity up to 7.5 times the LHC nominal value. To meet the requirements of a 1 MHz trigger...

Oral presentation (onsite or remote - not decided)

Highly compact and finely segmented electromagnetic calorimeters are required for applications in the LUXE experiment at DESY and at future electron–positron colliders as luminometers. A small effective Molière radius and high spatial granularity are essential for resolving electromagnetic showers in high-occupancy environments. At collider detectors, such calorimeters precisely define the...

Oral presentation (onsite or remote - not decided)

An ultra-compact sampling electromagnetic calorimeter based on tungsten absorber plates interspersed with thin silicon sensor layers was tested in an electron beam at DESY in June 2025. The thickness of the tungsten plates amounts to 1 radiation length, and are separated by only 1 mm. Data were collected with electron energies ranging from 1 to 6 GeV. The ongoing analysis includes measurements...

Oral presentation (onsite or remote - not decided)

To match the physics goals of future Higgs factory to secure the required precision of luminosity measurement, luminosity detectors need to be positioned with micrometer precision. 
Last year, prototype of  a highly compact and granular positron calorimeter (ECAL-P) for LUXE experiment was tested at the DESY electron beam. The design of ECAL-P was based on the concept proposed for luminosity...

Oral presentation (onsite or remote - not decided)

Highly granular silicon-tungsten calorimeters, originally developed for precision measurements at future Higgs factories, provide excellent spatial sampling of electromagnetic showers together with compact transverse shower development. These features also make them attractive for experiments searching for feebly interacting particles, where the reconstruction and separation of nearby photons...

Oral presentation (onsite or remote - not decided)

The Silicon-Tungsten Electromagnetic Calorimeter (SiW-ECAL), is one of the key sub-detector for the ILD Detector Concept and is being investigated as a component of future fixed target experiments looking for Dark Photons (EBES, LUXE, SHiP, Lohengrin).
After many iterations and tests, an ultimate version of the front-end boards based on SKIROC2 ASICs from the Omega lab, and a new assembly...

Oral presentation (onsite)

Precision measurements of the Higgs boson and electroweak interactions at future $e^+e^-$ collider experiments, such as the ILC, CLIC, and FCC-ee, are crucial for exploring new physics. Achieving this requires a high-granularity electromagnetic calorimeter, for which the silicon-tungsten electromagnetic calorimeter (SiW-ECAL) is one of leading candidates. While previous physics prototypes...
