Frascati Detector School

21 Mar 2018, 09:00 → 23 Mar 2018, 13:00 Europe/Rome

Salvini (LNF)

The school has the goal of discussing present particle detection techniques, with an emphasis on hands-on construction and operational experience, with the goal to be of use for young researchers. The present edition is focused on calorimetry and gas detectors. Morning seminars are followed by four parallel afternoon laboratory sessions. Future challenges and directions in the field are discussed the last of the three days of the school. School responsible: T. Spadaro Organizers: G. Bencivenni, D. Domenici, G. Felici, S. Miscetti

2 Gas detectors: general principles

Gas-based detectors measure the trajectories of charged particles through the ionisation electrons that are deposited in the gas. An electric field, and sometimes a magnetic field, guide(s) these electrons to amplification structures where an avalanche occurs. Avalanches produce electrons and ions and it is their motion that generates electric signals on the read-out electrodes. In this presentation we review these mechanisms.

11 High-granularity calorimetry

Calorimetry in high-energy physics is rapidly evolving, with new specifications (e.g. higher energies, enormous particle densities) and a wide variety of technologies, both for signal creation and detection. Advances in large-area highly-segmented detectors based on, for example, silicon and scintillators, are providing possibilities for high-granularity calorimetry, providing unprecedented levels of information from particle showers. This talk focuses on one example of high-granularity calorimetry: The CMS HGCAL, being designed to replace the existing endcap calorimeters for the HL-LHC era. It is a sampling calorimeter, featuring unprecedented transverse and longitudinal readout segmentation for both electromagnetic (CE-E) and hadronic (CE-H) compartments. This will facilitate particle-flow calorimetry, where the fine structure of showers can be measured and used to enhance pileup rejection and particle identification, whilst still achieving good energy resolution. The CE-E and a large fraction of CE-H will use silicon as active detector material. The sensors will be of hexagonal shape, maximizing the available 8-inch circular wafer area. The lower-radiation environment will be instrumented with scintillator tiles with on-tile SiPM readout. This concept borrows heavily from designs produced by the CALICE collaboration - calorimetry for ILC etc. - but the challenges of such a detector at a hadron collider are considerably larger than at the ILC. In addition to the hardware aspects, the reconstruction of signals - both online for triggering and offline - is a quantum leap from existing detectors. We present the ideas behind the HGCAL, its current status including design and expected performance, and the challenges ahead.
