Design and Construction of a Test Modulator at LNF

C. Di Giulio, B. Buonomo, Fabio Cardelli, Riccardo Ceccarelli et autres

High-power modulators play a crucial role in accelerators as the DAФNE LINAC at Laboratori Nazionali di Frascati (LNF) of INFN. Their continuous operation at LNF's LINAC (over 4500 hours/year) limits opportunities for hands-on training and system upgrades. To address this, a pulsed …

Search for a new 17 MeV resonance via $e^+e^-$ annihilation with the PADME Experiment

F. Bossi, R. De Sangro, C. Di Giulio, E. Di Meco et autres

The PADME Experiment at the Frascati DA$Φ$NE LINAC has searched for a hypothetical particle with mass around 17 MeV, commonly referred to as the X17, using a positron beam incident on a fixed target. The beam energy was varied between 262 and …

DAΦNE -2023/24 Activity report

C. Milardi, D. Alesini, Mostafa Behtouei, S. Bilanishvili et autres

The DAΦNE operations during the last year have been devoted to deliver a statistically significant data sample to perform the first-ever measurement of kaonic deuterium X-ray transitions to the fundamental level. Operations for the SIDDHARTA-2 detector using a deuterium gas target started …

Beam diagnostics with silicon pixel detector array at PADME experiment

Susanna Bertelli, F. Bossi, C. Di Giulio, E. Di Meco et autres

Abstract During 2022 data taking (Run III) PADME searched for a resonant production and a visible decay of the X17 particle into e+e-. A precise knowledge within 1% uncertainty of the number of positrons was required for the observation. To that purpose, …

Design and performance of the front-end electronics of the charged particle detectors of PADME experiment

Susanna Bertelli, F. Bossi, S. Ceravolo, G. Corradi et autres

Abstract The PADME experiment at LNF-INFN employs positron-on-target-annihilation to search for new light particles. Crucial parts of the experiment are the charged particle detectors, composed of plastic scintillator bars with light transmitted by wavelength shifting fibers to silicon photomultipliers (SiPMs). The location …
