Ion and electron imaging
Applications of TPX3CAM include spatial and velocity map imaging of ions in time-of-flight mass spectroscopy; coincidence ion and electron imaging, and other time-resolved types of imaging spectroscopy. TPX3CAM is able to detect and time-stamp ion hits with 1.6 ns timing resolution. Ion momentum images for all fragment ions are recorded simultaneously. There is no need to gate the detector on a single fragment.
Image above: TPX3CAM is able to simultaneously image and time-stamp light flashes of more than 1000 photons with high quantum efficiency in the 400 to 1000 nm wavelength range. It can efficiently register ions impinging on an MCP (micro-channel plate) in the VMI (velocity map imaging) configuration. The MCP is coupled to a fast P47 phosphor, which produces light flashes in response to ions hitting the MCP. The TPX3CAM, placed outside of the vacuum, can detect light flashes from the phosphor.
