Timepix3 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

Beam Gas Ionization (BGI) Profile Monitor for the CERN Proton Synchrotron

An important measurement in the CERN Proton Synchrotron (CPS) for beam diagnostics is the transverse emittance. A new instrument to perform these measurements has been developed using Timepix3 hybrid pixel detectors. The basic principle of the instrument is as follows:  when a beam passes through the vacuum pipe it will ionize the residual gas and create negatively charged electrons and positively charged ions. By applying an external electric and magnetic field the electrons are accelerated down onto a detector, which in this case is the Timepix3, and based on the distribution of the...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
