HEXITEC

HEXITEC detector is a self-contained system that measures the energy and position of every incident photon in the 4-200 keV range.

HEXITEC

Overview of the HEXITEC

Each one of its 6400 pixels provides a full energy spectrum with an average energy resolution of 1 keV FWHM at 60 keV. This allows for information related to the X-ray emission spectra, and therefore material composition of the image to be obtained for every pixel. HEXITEC system requires only a mains power supply and ethernet connection to a PC or laptop. It is supported by our custom-built data collection GUI to operate the detector and provide calibrated spectra.

HEXITEC detector is formed around HEXITEC sensor, a novel energy-resolving pixelated sensor. The 2 x 2 cm sensor has 80 x 80 pixels on a 250 μm pitch and a three-side buttable design allowing it to be tiled into larger arrays. A 1 mm thick CdTe wafer is bump bonded to HEXITEC ASIC and mounted on an aluminium block. When a photon interacts with the sensor material it generates electron-hole pairs that drift in opposite directions due to the electric field generated by the high-voltage bias applied across the sensor.

HEXITEC software

Software for HEXITEC

Quantum Detectors have developed a dedicated software platform to leverage as much of the data from the sensor as possible. A custom GUI is used to collect data which can then be processed using the user’s preferred package, offering ultimate flexibility. The platform also allows previously captured data to be played back for viewing of spectral information throughout the scan. Python scripts are supplied as examples of how to access and further process the data.

The HEXITEC in Action

The data output by HEXITEC includes the energy and position of every event that occurred in each of the 5000 frames per second of data capture. The energy, spatial and temporal information is recorded and output, frame by frame. The aggregate data is integrated across the capture period to give a single energy histogram for each individual pixel. This format requires less data and so is quicker to analyse, making it useful for monitoring or for experiments that do not require event level statistics.

Features of the HEXITEC

Fully spectroscopic area detector

Collect energy and spatial information simultaneously. Unlike most area detectors currently available, the HEXITEC detector measures the energy and position of every incident photon in the 4-200 keV range. This provides the potential to open up novel techniques not previously possible, such as sSAXS (see our application feature below for more details).

High resolution, high-energy imaging system

With a resolution of ~1 keV FWHM at 60 keV, and operational range of 4-200 keV, HEXITEC is formidable and versatile detector.

Fully integrated

HEXITEC is a self-contained system that requires only a mains power supply and ethernet connection to a PC or laptop. This makes it particularly convenient to use.

Full access to the raw data

The data output by HEXITEC includes the energy and position of every single event that occurred in each of the 5000 frames per second of data capture. The energy, spatial and temporal information is recorded and output, frame by frame. This provides the potential to conduct high resolution temporal analyses of the data, or to conduct post-processing analyses to improve the quality of the data.
