Image intensifiers

Photomultiplier detectors

• Ultra fast response time• Transit time spread 20 – 100ps

(model dependant) • Gated photon counting detectors

have been used to accurately measure the distance to the moon to an accuracy of +/- 3mm

Image photon detectors

• 25 and 40 mm versions• Single photon counting• Resistive anode• X, Y, time output• Applications

– Chemical luminescence– Bio luminescence– Thermo luminescence– Missile detection

GUVI detector

• 25mm UV photon counting• MgF2 input window• Csl photocathode• Wedge and strip anode• 106 cps• 3x106 gain

HiContent & IRPICS Technology Transfer

Electronics & Ceramics Technology

MCP Detector R&D

Life Science Applications

Related Developments

• HiContent & IRPICS detector– Multi-channel photon detectors– Use same readout electronics as KTP project

• Stand alone HPTDC module– Hardware/software developed for HiContent & KTP

projects will be developed into a standalone module

KTP Project Objective

To develop a commercial imaging photon detector for life science applications, capable of

– Better than 50 picosecond resolution timing resolution (1 picosecond is a trillionth of second)

– High rate readout (>10 MHz)– Coarse spatial resolution (e.g. 100×100 pixels)– Integrated electronics & data analysis options

Called the Charge Division Imaging Readout detector (CDIR)

Electronics

• Project uses two Application Specific Integrated Circuits (ASIC) developed at CERN for particle physics applications in the LHC

• The NINO ASIC (top) is a fast amplifier/discriminator specifically designed for high rate applications with tight timing requirements

• The HPTDC ASIC (bottom) is a Time-to-Digital Convertor (TDC) for high rate applications, giving 25 picosecond resolution

Benefits for Photek

• Experience of working with ASICs in the context of photon detectors

• High time resolution electronics to match Photek’s best in class photon timing detectors

• Experience integrating readout electronics with hardware data analysis
