Description

The proven potential of 3D geometries at higher than $10^{16}$ $n_{eq}/cm^{2}$ radiation fluences, in combination with a small cell approach, makes them an excellent choice for a combined precision timing tracker. In this study, the timing resolution of a single 50 x 50 $\mu m$ 3D pixel cell is presented in various temperatures through charge collection measurements with discrete electronics in a laboratory setting. The series is complemented by an extensive test-beam campaign with 160 GeV SPS pions, using a multi-plane timing telescope with an integrated pixelated matrix. Through a varied incidence angle study, field uniformity, Landau contribution and collected charge are treated at incidence angles of +/- $12^{o}$. Using state of the art numerical methods, the choice of instrumentation on signal composition and induced bias on results is also evaluated.
