1. Photek Company Presentation Jon Howorth

2. Company Profile Located in St Leonards-on-Sea – South East England Established September 1991 Purchased assets of electro optics division of ITL 48 employees –11 sales/administrative –7 R&D –30 production/test Specialise in electro-optic detector design and manufacture

3. Sales Revenue Growth

4. Image intensifiers

5. 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

6. 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

7. UV optical monitor Photon imaging 170 to 550 nm Aligned with x-ray telescope Provides simultaneous visible, UV and x-ray images

8. GUVI detector 25mm UV photon counting MgF2 input window Csl photocathode Wedge and strip anode 10 6 cps 3x10 6 gain

9. HiContent & IRPICS Technology Transfer Electronics & Ceramics Technology MCP Detector R&D Life Science Applications

10. 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

11. 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)

12. 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

13. 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
