MiniPIX TPX3 Flex

The popular MiniPIX TPX3 device developed by ADVACAM can be integrated into our partners’ systems. However, the fancy metallic box of the standard MiniPIX TPX3 is not needed. The new MiniPIX TPX3 Flex module has been developed for the most straightforward possible integration into any system.

The device can be equipped with several sensor types differing in material and thickness. The standard options include Silicon (100, 300, 500, and 1000 µm) and CdTe (1000 and 2000 µm). Custom types such as GaAs or CZT are possible too.

The MiniPIX TPX3 Flex is a miniaturized and low-power radiation camera with particle tracking and imaging detector Timepix3 (256 x 256 square pixels with a pitch of 55 μm). The device’s chip is equipped with a sensor according to customer preference (standardly 300 μm thick silicon).

The Timepix3 detector is position, energy, and time-sensitive: For each ionizing particle (e.g., X-ray photon), it digitally registers its position, energy, time of arrival, and track shape – all information you can want. The other measures can often be calculated from the track shape (particle type, direction of flight, LET, charge …). The information on each detected particle is either read out immediately (pixel mode) at a maximum rate of 2.3 million hit pixels per second or accumulated in pair of images (frame mode) and read out later at a top speed of 16 frames per second.

The typical and intended applications of MiniPIX TPX3 Flex:

• Spectral X-ray imaging: X-ray fluorescence imaging, X-ray radiography (low flux)
• Energy dispersive XRD, SAXS, or WAXS: Monochromatic X-ray source is unnecessary! Even high energy for thick samples is possible (e.g., 100 keV)!
• Spectral gamma-ray imaging: scintigraphy or SPECT, radiography with isotopes.
• Radiation monitor1: particle type sorting, spectroscopy, directional sensitivity …
• Gamma camera: special shielded box and collimators available.
• Compton camera: particular software module available for image reconstruction.

The MiniPIX TPX3 Flex device is controlled via USB 2.0 interface with a standard μUSB connector. All major operating systems (MS Windows, Mac OS, and LINUX) are supported. The complex software PIXET PRO used for detector operation is provided for free. The extra software modules are available for special functions (e.g., coded aperture image reconstruction, Compton camera image and spectrum reconstruction, radiation field decomposition, and networking of many devices …)
