Radiation Hard 3D Silicon Pixel Sensors for use in the ATLAS Detector at the HL-LHC

Andreas Løkken Heggelund, Simon Huiberts, Ole Dorholt +11

The High Luminosity LHC (HL-LHC) upgrade requires the planned Inner Tracker (ITk) of the ATLAS detector to tolerate extremely high radiation doses. Specifically, the innermost part…

Velocity selected production of metastable positronium

C. Amsler, M. Antonello, A. Belov +52

Positronium in the metastable state exhibits a low electrical polarizability and a long lifetime (1140 ns) making it a promising candidate for interferometry experiments wit…

Producing long-lived Ps via laser excitation in magnetic and electric fields

S. Aghion, C. Amsler, M. Antonello +62

Producing positronium (Ps) in the metastable state is of interest for various applications in fundamental physics. We report here about an experiment in which Ps atom…
