THHΘR Cosmic Ray Sensor

Sensor

CHAOS Jr: HET BGO and 2× HETB.

  • BGO: 2 photodiodes × 2 gains = 4 channels
  • HETB: 2 detector × 2 segments × 2 gains = 8 channels

Electronics

  • single 5…20V power supply
  • 37 pin Omnetics Bilobe connector to the preamps board, A28200-037
  • detector bias voltage, positive or negative
  • 12 channel DORN readout, dual gain (with six preamps)
  • with Beau-SK type preamps
  • 10LC25 FPGA
  • ATtiny824-XF
  • AT45B161E for FPGA bitfile and data
  • 3.3V UART (optional RS485 half duplex) ifc to OBC
  • optional HSS serial ifc/spacewire.
  • optional MS5534 pressure sensor for balloon missions Layout

Transformer
