We describe first results obtained with a track structure imaging system for measuring the ionisation topology of charged particles in a low-pressure gas. The detection method is based on a time projection chamber (TPC) filled with low-pressure triethylamine (TEA). Images of ionisation tracks of electrons, protons, and heavier ions are presented and analysed.
We report about a nuclear track imaging system which is designed to study in detail the ionization topology of charged particle tracks in a low-pressure gas. The detection method is based on a time projection chamber (TPC) filled with low-pressure tr
In this paper, we present a software framework, S$pi$RITROOT, which is capable of track reconstruction and analysis of heavy-ion collision events recorded with the S$pi$RIT time projection chamber. The track-fitting toolkit GENFIT and the vertex reco
Measurements of proton-nucleus scattering and high resolution neutrino-nucleus interaction imaging are key to reduce neutrino oscillation systematic uncertainties in future experiments. A High Pressure Time Projection Chamber (HPTPC) prototype has be
The international PEN collaboration aims to obtain the branching ratio for the pion electronic decay $pi^+ to e^+ u_e(gamma)$, aka $pi_{e2}$, to a relative precision of $5times 10^{-4}$ or better. The PEN apparatus comprises a number of detection sys
An imaging system for measuring the spatial distribtion of charged particle tracks in a low-pressure gas is presented. The method is based on an optically read out time projection chamber. Results of experiments with fast heavy ions are shown.
