AuraTek Multi-Channel Photon Counter

The AuraTek-PCS is an innovative, photon counting system that combines a Multi-Anode MCP-PMT with the high performance TOFPET readout electronics. The easy-to-use system contains 256 independent, high performance photon counting channels, each having a time stamp with 44 ps resolution and timing performance of < 100 ps rms after amplitude walk correction. The system is self-triggering and event driven, with time and amplitude data provide for each photon detected. The maximum count rate for each channel is 160 kcps, with a maximum total system count rate of about 10 Mcps. An optional user provided event identifier can be time stamped and included in the data stream by replacing one of the 256 anodes with an external input. The 160 MHz clock used by the sensor head is available to synchronize external circuits, or optionally, the user can provide their own 160 MHz clock. A Gigabit Ethernet link (640 Mbps max data rate) makes the final connection to a data acquisition computer providing online data display and storage of raw data to disk for later processing. The AuraTek-PCS is available with any of Photek’s high sensitivity photocathodes, each providing high quantum efficiency with extremely low dark counts for optimal signal-to-noise performance. Customization of the AuraTek-PCS for your specific needs includes; fibre optic input window for proximity focusing, multi-photon pulse readout, and varying pixel size and geometry. Software is provided to allow real-time monitoring of data and to optimize data post-processing.

The AuraTek-Round is a next generation Multi-Anode Micro-Channel Plate Photo-Multiplier Tube (MCP-PMT). It can be configured as a multi-channel single photon counter or analog photon pulse analyzer. The 1024 individual anodes are arranged in a 32 x 32 pattern with 0.88 mm pitch, resulting in a 28.16 mm square active area. Customers can request custom configurations of the full 1024 anodes via high density connectors, or group the anodes to form unique readout geometries. The timing performance is state-of-the-art, with pulse rise-time of < 175 ps and single photon transit time spread of < 40 ps rms per channel. Ask our experts to help you select the best readout electronics for your application.

The AuraTek-Square is a next generation Multi-Anode Micro-Channel Plate Photo-Multiplier Tube (MCP-PMT). It can be configured as a multi-channel single photon counter or analog photon pulse analyzer. The 4096 individual anodes are arranged in a 64 x 64 pattern with 0.88 mm pitch, resulting in a 53 mm square active area. The overall tube is 59 mm square, enabling efficient tiling of multiple AuraTek-Square’s to cover large areas. Customers can request custom readout configurations of the full 4096 anodes via high density connectors, or group the anodes to form unique readout geometries. The timing performance is state-of-the-art, with pulse rise-time of < 175 ps and single photon transit time spread of < 40 ps rms per channel.
