“…The sample contained a square lattice having the same in-plane dimensions and a double dislocation. Data was acquired at the COSMIC beamline of the Advanced Light Source using a novel Timepix-based detector [42][43][44] and σ-polarized light. This detector can rapidly count single X-ray photons scattered from the sample.…”

“…X-ray scattering was conducted at the COSMIC-Scattering beamline at the Advanced Light Source, Lawrence Berkeley National Laboratory, and at the Coherent Soft X-ray (CSX) beamline at the National Sychrotron Light Source II, Brookhaven National Laboratory. The diffracted photons were detected using a Timepix [42][43][44] based soft Xray detector at ALS and fast CCD detector at CSX. The diffraction experiment was performed in a reflection geometry as shown in Fig.…”

“…The incoming neutron beam was collimated down to 1 × 1 cm 2 using Cd-slits to reduce the hit-rate on the detector to be well below the saturation limit to avoid loss of photons, while the setup would have allowed to open the slits to 4 × 4 cm 2 , potentially increasing the flux by a factor of 16. At present, the Timepix4 chip 31 is already being developed and will potentially offer an increase in hit-rate roughly by an order of magnitude compared to Timepix3 3 , with each new generation of Timepix chip presumably increasing the maximum hit-rate further.…”

Imaging using scintillators is a widespread and cost-effective approach in radiography. While different types of scintillator and sensor configurations exist, it can be stated that the detection efficiency and resolution of a scintillator-based system strongly depend on the scintillator material and its thickness. Recently developed event-driven detectors are capable of registering spots of light emitted by the scintillator after a particle interaction, allowing to reconstruct the Center-of-Mass of the interaction within the scintillator. This results in a more precise location of the event and therefore provides a pathway to overcome the scintillator thickness limitation and increase the effective spatial resolution of the system. Utilizing this principle, we present a detector capable of Time-of-Flight imaging with an adjustable field-of-view, ad-hoc binning and re-binning of data based on the requirements of the experiment including the possibility of particle discrimination via the analysis of the event shape in space and time. It is considered that this novel concept might replace regular cameras in neutron imaging detectors as it provides superior detection capabilities with the most recent results providing an increase by a factor 3 in image resolution and an increase by up to a factor of 7.5 in signal-to-noise for thermal neutron imaging.

A: We present the development of a single-photon detector and the connected readout electronics. This 'hybrid' detector is based on a vacuum tube, transmission photocathode, microchannel plate and a pixelated CMOS read-out anode encapsulating the analog and digitalfront end electronics. This assembly will be capable of detecting up to 10 9 photons per second with simultaneous measurement of position and time.The pixelated read-out anode used is based on the Timepix4 ASIC (65 nm CMOS technology) designed in the framework of the Medipix4 collaboration. This ASIC is an array of 512 × 448 pixels distributed on a 55 𝜇m square pitch, with a sensitive area of ∼ 7 cm 2 . It features 50-70 e − equivalent noise charge, a maximum rate of 2.5 Ghits/s, and allows to time-stamp the leading-edge time and to measure the Time-over-Threshold (ToT) for each pixel. The pixel-cluster position combined with its ToT information will allow to reach 5-10 𝜇m position resolution. This information can also be used to correct for the leading-edge time-walk achieving a timing resolution of the order of 10 ps.The detector will be highly compact thanks to the encapsulated front-end electronics allowing local data processing and digitization. An FPGA-based data acquisition board, placed far from the detector, will receive the detector hits using 16 electro-optical links operated at 10.24 Gbps. The data acquisition board will decode the information and store the relevant data in a server for offline analysis.These performance will allow significant advances in particle physics, life sciences, quantum optics or other emerging fields where the detection of single photons with excellent timing and position resolutions are simultaneously required.
