Photek offers a range of ultra-fast MCP Photomultiplier detectors for the scientific community. Each detector is customised and may be supplied with a choice of input window, photocathode, MCP configuration, pulse rise time and gating options.

The current PMT family includes the following detectors:

PMT X10 PMT X13 PMT X18 PMT X25 PMT X40

Where X defines the MCP configuration and may be 0, 1, 2 or 3 gain stages and the number following this corresponds to the active diameter of the detector. For example a PMT213 is a two stage 13 mm detector.

Each MCP gain stage broadens the electron pulse time spread as well as increasing the gain. Small pore MCPs have faster time response than standard MCPs. Our PMT X10 and PMT X13 use small pore MCPs and have the fastest time response in our product range. Time response is improved in small detectors, because of reduced capacitance and hence smaller CR time constant.

All tubes have metal-ceramic construction, with remotely processed cathodes to minimise noise and maximise QE at the customers chosen wavelength. All tubes use a mesh to electrically screen the anode and improve the rise time.
