TPX3Cam - fast optical camera for nanosecond photon time stamping
TPX3Cam, a game changer in single particle counting imaging
The TPX3Cam is a fast optical camera for time stamping of optical photons. It is based on a new silicon pixel sensor, which in combination with the Timepix3 ASIC and readout, is suitable for a wide range of applications which require time-resolved imaging of electrons, ions or single photons.
The TPX3Cam can be easily integrated both in tabletop lab setups, as in synchrotron or free-electron-laser environments.
Ion and electron imaging
Applications of TPX3Cam include spatial and velocity map imaging of ions in time-of-flight mass spectroscopy; coincidence imaging of ions and electrons, and other time-resolved types of imaging spectroscopy. TPX3Cam is able to detect and timestamp ion hits with 1.6 ns timing resolution, thus making it possible to record ion momentum images for all fragment ions simultaneously and avoiding the need to gate the detector on a single fragment.
Single photon imaging (FEL)
The intensified version of TPX3Cam can be single photon sensitive. In this configuration the camera is employed in combination with an off-the-shelf image intensifier. The applications include the wide-field time-correlated single photon counting (TCSPC) imaging, phosphorescent lifetime imaging and any applications requiring time-resolved single photon imaging.
Benefits of TPX3Cam
Increased light sensitivity silicon sensor
● Wave length range: 400 - 1000 nm
● Per pixel simultaneous detection of time (ToA) and intensity (ToT)
● Time resolution 1.6 ns, effective frame rate > 500 MHz
● Lossless, data driven readout up to 80 Mhits/s
● Flexible optical design outside of vacuum
In TPX3Cam all individual pixels function independently and are able to time stamp incident ‘events’. This transforms the imaging sensor into an array of fast digitizers with both spatial and temporal resolutions acting in parallel so multiple ion species can be registered simultaneously allowing for coincidence and covariance analyses.
ASI Ltd in the Netherlands also supply LynX series detector which is a hybrid pixel detector suitable for X-ray detection, imaging and tomography applications. Please see the LynX family. And ASI's Chee-tah is a hybrid pixel Detector Camera suitable for TEM applications. Chee-tah's superior sensitivity and speed offer unprecedented possibilities for obtaining electron diffraction, imaging, and tomography, which are commonly used in diffraction experiments. Chee-tah's high-speed features make it an ideal tool for observing dynamic processes and capturing rapidly decaying signals. Please see the Chee-tah family.
