  1. EC interface with PDM

  2. PDM unit description - The PhotoMultiplier (MAPMT) and the Filters -The ASIC (ASIC) - The Elementary Cell (EC) - The High Voltage Power Supply (HVPS) and Switches (SW) • The PDM Board (PDMB)

  3. Size and Power estimation need to becomplete

  4. Electrical mechanical Interfaces PDM board (Pierre or Salleh) HV boxes (Philippe Gorodetzky) Mechanical Interfaces PDM structure layout (Pierre) PDM board (Pierre or Salleh) HV Box Design (Philippe Gorodetzky)

  5. Defineelectrical interfaces betweenSubsystems Power use (voltage, current …) Mass and size Grounding plan Connectors type and gender, locking Sub-system pinout Wires type (flex, HT, standard,…) CAO Model version updated. Plan to power on Ground

  6. Interfaces PDM <-> DP

  7.

  8. PDM unit description - The PhotoMultiplier (MAPMT) and the Filters -The ASIC (ASIC) - The Elementary Cell (EC) - The High Voltage Power Supply (HVPS) and Switches (SW) • The PDM Board (PDMB) • Define external interfaces

  9. Interfaces PDM <-> DP

  10. Gondola CNES equipments • SIREN (TM/TC) 290 x 285 x 84 mm, 3.175 kg 12-18V, 13 W 24 H autonomy with 3.9 kg batteries • ICDV (Attitude measurement, shock, T°…) 210 x 175 x 88 mm, 1 kg 12-28V, 10 W Inertial measurement unit : 3 gyrometers +/- 300°/s 3 accelerometers +/- 18g magnetometer 3 axis, Attitude restitution : ~1°, 100Hz Accelerometer 3 axis +/- 50g, 0-800Hz 1 PT100 thermal sensor -60 +100°C 23 H autonomy with 1.2 kg batteries

  11. IR Camera ?

  12. Interfaces • Connectors type and gender, locking • Connectors tests for AIT • Protocol to Nosyca? • Protocol to Siren? • DefineNosyca, Siren, DP interfaces • Provide Tests Connectors for AIT • IRcamera, mechanical & electrical interfaces • Pixels numbering on the EC Unit • Define and RoutingHarness • FixHarness • External Power connectors. • Power budget on eachsub system • Pack batterydefinition

  13. Environment • Thermal studies to 10°C guaranted ? • Heating or cooling ? • Groundingscheme • Power supply (Pack Batteries 250W/34.5Ah, 28V) enough? • Heating on L1? Thermal studies? • If heating power needed • On the Spider? Electricalheating or routing DP heating? • Wifi Antenna power? Direction? EMC? Wiredaccess possible withNoscycainstead of Wifi? • Shieldingscheme (wifi perturbation?) • Test withNosyca simulator? EGSE? • Transport vibration? • ESD discharge due to Lens
