Timepix Projects

3D Charged Particle Tracking

The core of many high energy particle physics experiments is charged particle tracking. By using ASICs that can accurately measure time in a Time Projection Chamber, one can directly reconstruct the 3D track of passing charged particles.

Another example of the use of Timepix3 is in the beam telescope of the LHCb Vertex Locator group. In this case 8 Timepix3 layers accurately define the position and the time of passing of the charged particle in the Device Under Test (DUT). A spatial and time resolution of 2 um and 0.35 ns, respectively, has been achieved, which allow for detailed...Read more


A pilot project, called CERN@School, has been launched by the Simon Langton School in Canterbury, England, with the aim of delivering kits together with the associated teaching material, to a large number of schools. High-school students are encouraged to initial their own research projects using the kits.

CERN@school aims to inspire the next generation of physicists and engineers by giving participants the opportunity to be part of a national collaboration of students, teachers and academics, analysing data obtained from detectors based on the ground and in space to make new,...Read more

Timepix and Timepix3 Optical Cameras

Resolving the time evolution of fast processes, measuring the time-of-flight of particles or lifetime for fluorescent processes, and looking at time correlations in spatially resolved events are interesting applications, which often require a fast optical camera. When an event-triggered time measurement is needed with best possible spatial and time resolution, silicon pixel arrays offer the best performance. We describe here fast optical cameras based on a new silicon pixel sensor, which in combination with the Timepix chips, will provide nanosecond scale time resolution and high quantum...Read more

Timepix at the International Space Station

In 2012 the Timepix chip arrived at the International Space Station. This was the culmination of efforts by collaboration members at the Institute of Experimental and Applied Physics in Prague and the University of Houston, Texas, to use the chip for monitoring the radiation environment of the station. Five chips were plugged into the USB ports of the station laptops and immediately started delivering data to the Earth-based team in Houston. This team is now carefully analysing the data and comparing it with data from the more conventional but rather bulky area-monitors.

The picture...Read more

Timepix in NASA's Orion Rocket

In December 2014, two Timepix chips were incorporated into a battery-operated system that flew on the NASA Orion rocket. The development, which was driven by the University of Houston, provides a very compact and low-power solution to measure the radiation fields to which astronauts are exposed. The approach has been adopted as the baseline for radiation measurements for the Orion project.Read more
