AdvaPIX

Advacam’s AdvaPIX camera is designed with special emphasis to performance and versatility that is often required in scientific research world. The camera module contains a single Timepix device with a quick parallel readout. It allows a sustainable frame rate of up to 1700 frames/ second that makes it optimal for spectral imaging and ion detection. Advanced data processing algorithms allow ion detection with spatial resolution of up to 200 nm.

Description

Click for datasheet Advacam’s AdvaPIX can be used in variety of applications such as fast radiography (X-rays, neutrons, ions), particle tracking, spectroscopic imaging (each pixel records the energy spectrum), Time-of-flight imaging, multilayer Compton camera (thin top sensor, thick bottom sensor). The sensor type and thickness can be customized as per requirements and can also be modified for neutron imaging by depositing converter layer (6LiF). The sensors can be adapted for neutron imaging by deposition of converter layers. The spatial resolution in some applications, like thermal neutrons, can reach units of microns or even submicrometric level (ions).
The fast modules with Si or CdTe pixel detectors Timepix can be used in different configurations such as stack of several layers or tiling to cover larger area or combination of both. Each module contains single Timepix device with fast parallel readout up to per second independent of frame occupancy. A separate USB 3.0 communication channel for each device assures fast read-out of the whole modular system. All modules in the system can be operated synchronously or triggered independently.
