The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The scintillators are read-out by the wavelength shifting fibres coupled to the photomultiplier tubes (PMTs). The analogue signals from the PMTs are amplified, shaped, digitized by sampling the signal every 25...
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The High-Luminosity phase of LHC, delivering 5 to 7.5 times the LHC nominal instantaneous luminosity, is expected to begin in 2030. TileCal will require new electronics to meet the requirements of a 1 MHz...
We report the performance of the CALICE scintillator electromagnetic calorimeter (Sc-ECAL) large prototype measured with 0.5–5.8 GeV electrons at KEK in May–June 2025. Because the calibration LEDs were not operational, we determined single-photo-electron (SPE) gains directly from MIP-like spectra using a frequency/peak-finding method. The calibration chain includes channel-by-channel pedestal...
The future Higgs Factory collider will provide unprecedented precision to significantly sharpen measurements and understanding of the Higgs boson. An attractive capability could come from using monolithic active pixel sensors (MAPS). A MAPS prototype program is developing sensors with tracking performance as first priority; implementation for the electromagnetic calorimeter (ECal) is a...
The high-granularity Silicon-Tungsten Electromagnetic Calorimeter (SiW-ECAL) was proposed as early as around the year 2000. The project is completing its technological prototype phase, and is now advancing toward an engineering prototype, in preparation for any future electron-positron collider.
Building upon insights from previous studies considering recent advancements in electronics and...
For future $e^{+}e^{-}$ Higgs factories two processes have been proposed for precision integrated luminosity measurements, Bhabha scattering and diphoton ($\gamma\gamma$) production. To address some proposals aiming for $10^{-4}$ or even $10^{-5}$ precision on integrated luminosity, two studies were conducted. The first study, summarized in this talk, focused on upgrading the existing...
Highly compact and granular electromagnetic calorimeters are necessary for luminometers in experiments at electron-positron colliders or for the measurement of the positron multiplicity and energy distribution in the laser-electron scattering experiment LUXE investigating strong field QED. In the former, Bhabha scattering is used as a gauge process. Using a highly compact calorimeter, i.e....

In this talk, we aim to summarize recent simulation studies on the exploitation of silicon-tungsten high-granular calorimeter concepts in Dark Matter and direct searches for new particles in novel experiments. These concepts have been tailored for collider physics, specifically Higgs Factories and the LHC. However, the intrinsic capabilities of these designs, which aim for a low Molière radius...
Noble liquid-based electromagnetic calorimetry is a promising option for next-generation high-precision detectors at future lepton colliders, including potential Higgs factories. Its key advantages — such as excellent energy resolution, uniform and stable response, and the ability to achieve fine spatial segmentation — make it ideal for detailed event reconstruction and control of systematic...
