Related parts:

• Dosimeter Readout, NT-Dose-4001. The Dosimeter Readout is used in conjunction with a RADFET to determine the accumulated dose during space missions.
• RADFETs. MOSFET transistor designed for radiation detection. The Dosimeter Readout can be used with most RADFETs

PnP Dosimeter in standard PnP flight box. Up to 8 RADFET dosimeters & Dosimeter Readouts can be used with a single Gen 1 ASIM. More compact units based on more advanced ASIMs are under development.

Key features:

• Meets the AFRL Space Plug-and-Play Avionics (SPA) standards.
• xTEDs supports polled and streamed messages.
• Package supports both USB and SpaceWire interfaces.
• Up to 8 Readout Dosimeters and RADFET dosimeters (with selectable sensitivities) per PnP package.
• Two Readout Dosimeter operating modes - low and high sensitivity. In low sensitivity mode, chip can be un-powered and still accumulate dose.
• Built-in temperature monitor.

Output signal as a function of dose.

Benefits:

• Meets the AFRL Space Plug-and-Play Avionics (SPA) standards.
• Support rapid assembly Plug-and-Play satellites.
• The 8 dosimeters per PnP package can be used to provide substantial information on the space environment during the mission.

Status: PnP dosimeter developed and demonstrated. The Dosimeter Readout has been fabricated and tested electrically and with radiation. Additional tests of the Dosimeter Readout are planned in late 2009 and early 2010.

Available for purchase:

• PnP dosimeters will be fabricated to order.
• Nu-Trek staff can customize the on-board dosimeters to meet mission requirements.

Subject to ITAR control: Yes
