| # SPACEDOS02 - PIN diode dosimeter for manned spacecraft | ||
|
|
||
| SPACEDOS is a active cosmic radiation dosimeter for use onboard manned spacecraft. It is designed as a replacement to standard passive detectors. | ||
|
|
||
|  | ||
|  | ||
|
|
||
| The device is used onboard ISS. The following pictures show the processed data from the flight. Here is a radiation map, where the [South Atlantic Anomaly](https://en.wikipedia.org/wiki/South_Atlantic_Anomaly) is visible. | ||
|
|
||
|  | ||
|
|
||
| The following spectrum is a cumulative sum of all the measured particles during the flight. | ||

| # SPACEDOS03 - semiconductor-based ionizing radiation spectrometer | ||
|
|
||
|  | ||
|
|
||
| SPACEDOS03 is an open-source semiconductor particle detector (dosimeter and spectrometer) for space applications. The detector is based on a silicon PIN diode. The Detector is designed as autonomous for long-term measurement campaigns and therefore contains its power source from high-capacity battery cells and a recording medium in the form of an industrial SD card. The device is designed to be able to work for half a year continuously. | ||
|
|
||
| The detector is mounted into a 3D-printed box that contains positions for passive TLDs and track detectors. The main purpose of the device is experimental testing of radiation shielding materials in the real environment. | ||
|
|
||
| ## Parameters | ||
|
|
||
| * Silicon PIN diode detector with 44 mm³ detection volume | ||
| * Effective number of energy channels 470 ±3 | ||
| * Deposited energy ranges from 60 keV to 7 MeV | ||
| * Energy measurement resolution 15 ±2 keV (depending on calibration method and type of particles) | ||
| * Power supply 18650 Li-ion cells | ||
| * Integration time depends on firmware setup | ||
| * Data storage device: Industrial SLC SDcard | ||
| * Dimensions - 120 x 90 x 62 mm | ||
| * Weight - 447 grams (including SAFT batteries) |
