TPX3 based scanner for XRD/XRF

Popis výsledku v původním jazyce

TPX3 based scanner for XRD/XRF The whole system consists of multiple translation stages, a colimation system and high power X-ray Tube in precise geometry to allow the measurement of XRD. The main part of the scanner is the detector itself. The large area (2×2 tiles) imaging TPX3 detector Fully sensitive CdTe detection area – with central hole between sensor tiles suitable for XRD scanner. Suitable for NDT method of XRT in nuclear energy. Features Readout chip type: Timepix3; Pixel size: 55 × 55 μm; Sensor resolution: 55 × 55 μm; Sensor res: 512 × 512 pixels; Time resolution:11,6 ns; Power:external 12 V DC; Sensor material: 1000 μm CdTe; Dark current: none; Interface:USB 3.2 (Super-Speed); Maximum readout speed: 47 million pixels / s; Dimensions: 210 × 94 x; External temperature stabilization Temperature stabilization of the required. Connect the water cooler hoses to the device connectors. The temperature should be set to 22 °C. The device will automatically shut down after chip or CPU temperature exceeds 55°C. Electrical Specification TA = 25 °C Gained parameters of the device TA = 25°C, power supply VCC = 24V Modes of readout chip operation The ionizing radiation particle interacts with the sensor material creating an electric charge. This charge is collected by electric field and brought to pixel preamplifier where it is amplified and shaped forming triangular voltage pulse. The amplitude and duration of this pulse is proportional to energy deposited by particle within the pixel. The situation when the voltage pulse amplitude in particular pixel exceeds preselected threshold value is called “event” or “hit”. Each pixel contains three digital counters (10, 14 and 4 bits). These counters are used differently according to measurement type and mode. There are three basic values which can be measured and stored in counters of each pixel: Number of Events = number of events (hits) in the pixel during exposure time (this mode is suitable mainly for frame type readout). Time-over-Threshold (ToT) = measured as number of periods of 40 MHz clock signal (25 ns step) when amplifier output signal stays over the energy threshold. The ToT can be transformed to energy in keV using per-pixel-calibration function. The coefficients for per-pixel-calibration are unique for each detector pixel and they are stored in configuration file delivered with device. The energy calibration is valid only for given values of other detector parameters as delivered in configuration file (especially threshold). Time-of-Arrival (ToA) = number of periods of 40 MHz clock signal (25 ns step) from start of exposure till the event is registered by pixel (i.e. pulse in pixel crosses the threshold). The range 409,6 μs. Additional 14 bits are added in FPGA in readout electronics so that the total range is 6,7 seconds. The additional bits are usable only if the pixel hit rate is below maximal value (see the table of Performance characteristics). Fast-Time-of-Arrival (FToA) = time difference between event detection and next clock signal measured with step of 1,5625 ns. Range is 4 bits. The combination of ToA and FToA gives precise time of event detection in nanoseconds using following formula: Time [ns] = ToA*25 – FToA*1,5625 ToA and FTOA are combined by software. If saved, then ToA and FToA are stored as separate items. Measurement types: Frame type measurement No data is sent out of device during the exposure time. All measured events are accumulated in counters of pixels. Event counter is incremented and ToT is integrated for all events. The measured data is read-out after end of exposure time for all pixels with nonzero content. No measurement can be performed during readout process. Pixel type measurement Information about all hit pixels is read-out immediately and continuously during exposure time. The whole system consists of multiple translation stages, a colimation system and high power X-ray Tube in precise geometry to allow the measurement of XRD.
