Abstract
Abstract
The spatial and temporal performance of a four-plane system
composed of silicon sensors bump-bonded to Timepix4 ASICs is
assessed with a 180 GeV/c mixed hadron beam at the CERN SPS and
reported in detail. Particle tracks are reconstructed using
time-space measurements from the four detector planes, two
100 μm planes perpendicular to the beam and two 300 μm
sensors under an angle of 9°. The spatial hit resolution
is assessed to be (15.5 ± 0.5) μm and (4.5 ± 0.3) μm
for 100 μm and 300 μm thick sensors, respectively.
The timestamps from the detectors are also measured with fine
precision, yielding time resolutions of (452 ± 10) ps,
(420 ± 10) ps, (639 ± 10) ps, (631 ± 10) ps for the two
100 μm and two 300 μm thick sensors respectively.
These measurements are combined to a track time resolution of
(340 ± 5) ps. The design of the detector system is described
together with its data acquisition system, operational
infrastructure, and dedicated software.
