  1. MAIA Sensor System: Designing an Intensified Photodiode Mount Keizo Gates Akamai Internship

  2. Overview • MAIA Laser System • MAIA Sensor • MAIA Receiver • The Need for a Mount • The Design Process • The Final Result

  3. The Big Picture • Existing MAIA Laser in the Beam Director/Tracker (BD/T) telescope • 2500 Hz max rep rate • 11 ns pulse length • 54 MW peak power • AEOS 3.67 m telescope • Largest in the Dept of Defense • Using Coudé room 5 • The MAIA Sensor System

  4. The MAIA Sensor System • Used in the AEOS • Consists of • Collection optics • Intevac Intensified Photodiode sensor • Supporting electronics • Real time data collection and processing • RT Linux PC • Signal processing • Software

  5. Bread-board Optics A refrigeration unit Intensified Photodiode sensor inside Overall system enclosure The MAIA Receiver Box

  6. Identify the Problem • Need to • Secure the IPD Sensor • Mount 15mm lens & allow for 10mm focus adjustment • Contain the BiasT & Amp Products for Research Thermal Cooler

  7. Design Process • Brainstorm possible solutions • Sketch, research opto-mechanics • Gather input • Select the best idea • Detail design • Communicate the result • Prototype the product

  8. Design Details • Constraints, Issues & Concerns • Length limitations • Fixing the sensor without stress • Containing BiasT, Amplifier, & Wires • Securing the lens assembly • Temperature

  9. Design Analysis T1 T2 • Amp heat concerns • P=k*A/L*∆T • P=1 Watt, solve eq; ∆T << 1 • Thermal expansion concerns • ∆x = CTE*∆T*d • Solve for ∆x; ∆x = .013 mm << tolerances • Neither are major issues • Small part • Small temperature change 1 W Power

  10. Final Design Part List

  11. Final Design Cross Section

  12. Final Design CAD

  13. Conclusions • Design consists of one custom part • Interfaced with Thorlabs components • Two modified Thorlabs components • Next Steps • Machine the parts • Assemble the parts • Install into the MAIA Sensor box
