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

CERN@School

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

In contrast to conventional radiotherapy using photons, ion beam radiotherapy enables better focusing of the radiation on the target, and thereby improved sparing of the surrounding healthy, and potentially sensitive, organs. At the same time, this...Read more

Online Colour X-ray Computed Tomography

The spectral capabilities that the Medipix3 chip provides are being explored in the domain of X-ray CT imaging. The aim is to realise a system that by using advanced algorithms is capable of online adaption of the data taking strategy thereby limiting the required dose while still obtaining elemental identification of the materials of the object under study. The example below shows a sample consisting of a Perspex rod wrapped with a copper foil and cadmium foil. One can clearly see that the various materials are identified unambiguously; blue – plastic...Read more
