Abstract
Abstract
High precision experiments with muons and pions often
require tracking charged particles with O(100 μm)
single-hit resolution, possibly with particle identification
capabilities, down to very low momenta (p ≲
100 MeV/c). In such conditions, the particle trajectories are
strongly affected by the interaction with the detector material, and
the reconstruction of the kinematic observables consequently
deteriorates. A good compromise between resolution and material
budget can be obtained with a Time Projection Chamber (TPC), if very
light gases and a high-granularity readout are used. In this paper,
we present a characterization of the GridPix detector in
helium-isobutane gas mixtures, within a TPC with 9 cm maximum
drift. Measurements of the main electron drift properties for these
gas mixtures are also presented.
