Method for measuring positron number in high intensity nanosecond positron bunches based on Poisson statistic / Rienäcker, B (CERN) ; Mariazzi, S (Trento U. ; TIFPA-INFN, Trento) ; Povolo, L (Trento U. ; TIFPA-INFN, Trento) ; Guatieri, F (Tech. U., Munich (main) ; Trento U.) ; Caravita, R (TIFPA-INFN, Trento) ; Penasa, L (Trento U. ; TIFPA-INFN, Trento) ; Pino, F (U. Padua, Dept. Phys. Astron.) ; Nebbia, G (INFN, Padua) ; Brusa, R S (Trento U. ; TIFPA-INFN, Trento)
A novel method for the measurement of the number of positrons contained in intense positron bunches is presented. The technique is based on the Poisson distribution of the number of gamma rays emitted by many simultaneous positron–electron annihilations in a small solid angle. [...]

Absolute fraction of emitted Ps determined by GEANT4 supported analysis of gamma spectra / Rienäcker, Benjamin (CERN ; Tech. U., Munich (main)) ; Gigl, Thomas (Tech. U., Munich (main)) ; Nebbia, Giancarlo (INFN, Padua) ; Pino, Felix (INFN, Padua) ; Hugenschmidt, Christoph (Tech. U., Munich (main))
The fraction of positronium (Ps) emitted from a surface of a germanium single crystal at high temperature is usually assumed to approach unity at zero positron implantation energy. In the experiment, however, the determination of the absolute Ps fraction is not straight forward since recording a reference spectrum with $100\,\%$ Ps formation remains demanding. [...]

A fiber detector to monitor ortho-Ps formation and decay / Rienäcker, Benjamin (CERN) ; Brusa, Roberto Sennen (U. Trento (main) ; TIFPA-INFN, Trento) ; Caravita, Ruggero (TIFPA-INFN, Trento) ; Mariazzi, Sebastiano (TIFPA-INFN, Trento) ; Penasa, L. (Trento U. ; TIFPA-INFN, Trento) ; Pino, Felix (U. Padua, Dept. Phys. Astron.) ; Ranum, Oline Aas (U. Amsterdam, GRAPPA) ; Nebbia, Giancarlo (INFN, Padua)
We describe a novel method to use a scintillating fiber detector similar to the Fast Annihilation Cryogenic Tracking (FACT) used at the antimatter experiment AE$\bar{g}$IS to monitor the presence of ortho-positronium. A single scintillating fiber was coupled to a photomultiplier tube and irradiated by flashes of about 6 x 10$^{6}$ 511 keV $\gamma$-rays produced by $\approx10\,\text{ns}$ long positron pulses. [...]

A low cost 2/3 of 4 $\pi$ detector for the study of Ps decay / Pino, F (INFN, Legnaro ; Padua U.) ; Fontana, C L (Padua U. ; INFN, Padua) ; Lunardon, M (Padua U. ; INFN, Padua) ; Moretto, S (Padua U. ; INFN, Padua) ; Stevanato, L (Padua U. ; INFN, Padua) ; Brusa, R (Trento U. ; TIFPA-INFN, Trento) ; Caravita, R (CERN) ; Mariazzi, S (Trento U. ; TIFPA-INFN, Trento) ; Penasa, L (Trento U. ; TIFPA-INFN, Trento) ; Povolo, L (Trento U. ; TIFPA-INFN, Trento) et al.
A large area low-cost detector for detailed studies of ortho-Positronium formation and decay is being designed. The detector will be made of four modules each consisting of a thin slab of YAP(Ce) scintillator read out by a multi-anode flat panel photomultiplier tube. [...]
