“…The detector was placed in the forward direction at 10 cm transversal and 10 cm along the beam axis (see figure 1b). In addition, the detector-sensor plane was tilted to the direction of the arriving particles in order to enhance the spectral-tracking resolving power [11].…”

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.

“…8) consists of two parts: the first part is the semiconductor detection layer (300 μm silicon in this case used for the energy range of 3 -60 keV), which is bump bonded to the second part, an Application-Specific Integrated Circuit (ASIC) readout chip containing preamplifier, Analog-to-Digital Converter (ADC), and a counter for each pixel. Data from the sensor can be read out as fast as 100 images per second (depending on the accompanying hardware interface [25][26][27][28]), which makes it ideal for particle tracking applications. On the other hand, long acquisition times on the order of minutes are possible, thanks to the sensor's noise-less output.…”

“…TIMEPIX processes signal from single-quantum events on-board using a megahertz frequency clock and multi-channel analyzer with 11.8k channels per pixel enabling measurement of the number of events, the energy, or the time of interaction. These features offer a wide dynamic range of the MINIPIX TIMEPIX in term of quantum sensitivity and noiseless particle type identification (neutrons, X rays, light, and heavy charged particles) as well as measurements of particle flux (from single particles up to 10 6 in event by event spectrometry tracking mode and 10 8 in integrated counting mode), linear energy transfer (0.1-500 keV/µm in silicon), or directional tracking in a wide field of view (2π solid angle) [40].…”
