Measured Properties of an Antihydrogen Beam
E. D. Hunter, M. Bumbar, C. Amsler +29
We report a factor of increase in the antihydrogen beam intensity downstream of ASACUSA's Cusp trap: atoms detected per -minute run. The beam contains many Rydberg…
R&D on a high-performance electromagnetic calorimeter based on oriented crystalline scintillators
M. Soldani, N. Argiolas, L. Bandiera +36
Although inorganic scintillators are widely used in the design of electromagnetic calorimeters for high-energy physics and astrophysics, their crystalline nature and, hence, their…
Towards a Study of Low Energy Antiproton Annihilations on Nuclei
Viktoria Kraxberger, Marcus Bumbar, Angela Gligorova +30
A study of antiproton annihilations at rest on thin solid targets is underway at the ASACUSA facility, which now features a dedicated beam line for slow extraction at 250 eV. The e…
Alignment of the CLAS12 central hybrid tracker with a Kalman Filter
S. J. Paul, A. Peck, M. Arratia +131
Several factors can contribute to the difficulty of aligning the sensors of tracking detectors, including a large number of modules, multiple types of detector technologies, and no…
A high-performance custom photodetection system to probe the light yield enhancement in oriented crystals
M. Soldani, L. Bandiera, L. Bomben +16
Scintillating homogeneous detectors represent the state of the art in electromagnetic calorimetry. Moreover, the currently neglected crystalline nature of the most common inorganic…
Upgrade of ASACUSA's Antihydrogen Detector
V. Kraxberger, C. Amsler, H. Breuker +35
The goal of the ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) CUSP experiment at CERN's Antiproton Decelerator is to measure the ground state hyperfine splitt…

Luca Bomben, Stefano Capelli, Chiara Fanzini +7
This article describes the design, assembly and characterization of a portable cosmic ray detector, developed by the INSULAB group and suitable for teaching activities aimed at hig…
Muon detection in electron-positron annihilation for muon collider studies
N. Amapane, M. Antonelli, F. Anulli +43
The investigation of the energy frontier in physics requires novel concepts for future colliders. The idea of a muon collider is very appealing since it would allow to study partic…
The ENUBET positron tagger prototype: construction and testbeam performance
F. Acerbi, M. Bonesini, F. Bramati +50
A prototype for the instrumented decay tunnel of ENUBET was tested in 2018 at the CERN East Area facility with charged particles up to 5 GeV. This detector is a longitudinal sampli…
Decay tunnel instrumentation for the ENUBET neutrino beam
F. Acerbi, A. Berra, M. Bonesini +56
The uncertainty in the initial neutrino flux is the main limitation for a precise determination of the absolute neutrino cross section. The ERC funded ENUBET project (2016-2021) is…
Polysiloxane-based scintillators for shashlik calorimeters
F. Acerbi, A. Branca, C. Brizzolari +46
We present the first application of polysiloxane-based scintillators as active medium in a shashlik sampling calorimeter. These results were obtained from a testbeam campaign of a…
The ENUBET narrow band neutrino beam
ENUBET Collaboration, M. Tenti, F. Acerbi +54
The narrow band beam of ENUBET is the first implementation of the "monitored neutrino beam" technique proposed in 2015. ENUBET has been designed to monitor lepton production in the…
Antiproton beams with low energy spread for antihydrogen production
M. Tajima, N. Kuroda, C. Amsler +23
A low energy antiproton transport from the ASACUSA antiproton accumulation trap (MUSASHI trap) to the antihydrogen production trap (double cusp trap) is developed. The longitudinal…
