X-ray fluorescence (XRF) imaging have been published addressing the non-destructive investigation of the elemental distribution in heterogeneous media in many microscopy imaging applications, especially when the separation of different elements are crucial. Usually, single pad detectors of high spectroscopic quality are used for the precise elemental analysis. By scanning the sample surface...
The excellent features of the state-of-the-art particle tracking hybrid detectors Timepix3 have been already shown. They are namely: High granularity (256 x 256 pixels with a pitch of 55 µm), spectral and temporal sensitivity. These detectors can be coupled with high-Z sensors such as CdTe, CZT or GaAs. The Timepix3 properties allow for suppression of secondary radiation generated inside of...
Timepix2 [1] is an improved version of the Timepix with advanced features and functionalities developed by the Medipix2 Collaboration at CERN. It is a frame-based readout chip featuring a 256x256 pixel grid with 55 µm pitch. The chip implements eight modes of operation, of which two allow simultaneous and six continuous measurements. In continuous modes, two sets of pixel counters are...
Compared to other radiotherapy modalities for cancer treatment, carbon-ion radiotherapy permits a higher dose concentration in targeted tumor volumes while better sparing patient’s healthy tissues. However, this benefit comes with the price of a higher sensitivity to any changes of the patient internal geometry due to movements, or tumor swelling and shrinkage. Monitoring methods of the...
The European Synchrotron Radiation Facility (ESRF) is being subjected to the second phase of its upgrade, the so-called EBS (Extremely Brilliant Source) upgrade. The new storage ring will be able to deliver X-ray beams with up a factor 100 increase in brilliance. In order to exploit these extended source capabilities ESRF has launched an ambitious instrumentation programme, focusing on high...
Fast-timing particle detection in the sub-nanosecond region is a challenge in high energy physics, space science and nuclear physics, as well as in bio-medical imaging instrumentation. The use of fast timing detectors (~10 ps resolution) is crucial for the successful exploitation of the full potential of the future LHC operation at the high luminosity, and will facilitate the search for...
The high beam intensity of linear accelerators such as the ESS linac implies that even a loss of a small fraction of the beam could result in significant irradiation and destruction of accelerator equipment. The Beam Loss Monitor (BLM) systems must be capable of detecting the smallest possible fraction of beam loss, approaching 0.01 W/m loss, preventing activation of machine components and...
Dry storage facilities necessitate a reliable safeguards technique which is able to detect any undeclared activities such as diversion, misuse, or theft of spent nuclear fuel assemblies in a cask. Many techniques based on gamma, neutron, or muon have been applied but suffered from low accuracy caused by shields of a cask. Therefore, the present authors developed a new tomography system...
The use of muons produced in the atmosphere for the scanning of the internal structure of big objects is known as muon tomography or muography. Being a non-invasive technique, it has enlarge their possible applications in the last years mainly due to the performance achieved in particle detectors. Nowadays this technique is used in such a different fields as archaeology, volcanology, nuclear...
