“…Currently detailed data analysis is in progress including quantitative and time-dependent results on radiation particle composition, particle component fluxes and directional distributions for energetic charged particles. This work extends the use of Timepix into open space started from ground-based [3] and atmospheric/aerospace [7] applications.…”

“…The quantum-imaging detection [13] and spectral-sensitive tracking [11,14] of single particles with the Timepix3 detector are illustrated in figure 1c. Together these techniques enable to detect single particle, selectively discriminate and analyze in high-resolution the deposited energy and direction of trajectory.…”

Monitoring and characterization of particle beams in wide-range is often necessary in research and many applications with particle accelerators. The quantitative measurement and evaluation of composition especially of high-intensity beams are limited and can become a challenge with conventional methods especially with simplified instrumentation for ease of deployment. For this purpose, we developed a novel technique based on high-resolution spectral-sensitive tracking of single particles scattered from the beam path by a thin foil. We use a compact radiation camera equipped with the semiconductor pixel detector Timepix3 together with dedicated Monte-Carlo simulations. Particle-event type discrimination and directional information are produced by the detector spectral-tracking response together with particle-type resolving power derived from experimental calibrations. Directional- and spectral-sensitive components can be resolved in wide field-of-view. Quantification of the primary beam intensity is extrapolated by numerical calculations. Demonstration and evaluation of the technique are provided by measurements with 33 MeV protons from a light ion cyclotron accelerator. Scattered particles originating from the thin foil, the accelerator beam nozzle, and the air space along the beam path are detected and evaluated.

“…The architecture provides dark-current free noiseless detection for single-quantum/photon counting sensitivity, per-pixel spectrometry, high granularity and particle tracking capability [2,10,15] rendering the device as an active nuclear emulsion [16]. The Timepix chip can be readout by compact readout electronics such as the miniaturized MiniPIX interface (shown in figure 1b) which serves as compact radiation camera [13,17] providing ease of use, room-temperature and vacuum operation. Control and configuration of the detector including on-line response, data readout and data pre-processing are performed by the PIXET software [18] on a standard PC running in Windows, Linux or MacOS.…”

Dynamic range and resolving power of the Timepix detector to heavy charged particles

The spectrometric and particle tracking response of the Timepix detector for charged particle detection was examined for energetic (i.e. penetrating) heavy charged particles in a wide range of energies and directions. The aim of this study was to examine the detector's resolving power including particles approaching the minimum-ionizing regime, in particular energetic protons. The per-pixel energy range, of importance namely for heavy charged particles, was also investigated. This work complements and extends the ongoing task to analyze and describe the response and resolving power of the detector in a wide range of particle types, energy (energy loss) and direction. The methodology of event discrimination in terms of these degrees of freedom was expanded and refined. Resolution and event classification were based on analyses of cluster morphology parameters together with spectrometric, tracking and correlated derived quantities such as linearenergy-transfer (LET) and ratio cluster height to cluster path length.
