ISS Science for Everyone

Science Objectives for Everyone
The Miniaturized Particle Telescope (MPT) is a two-element radiation detector that builds on the Radiation Environment Monitor (REM)/Timepix technology. REM units are already being flown as a technology demonstration on the International Space Station (ISS). The entire detector assembly is roughly the size of the palm of your hand. All power/data is done through two USB connections directly to a laptop. The MPT is a Commercial Off-the-Shelf (COTS) product, manufactured by Advacam. Timepix detectors are USB-powered particle trackers based on Medipix technology developed at the European Organization for Nuclear Research (CERN).

Experiment Description

Research Overview
The goal of the Miniaturized Particle Telescope (MPT) project is to demo the capability of determining the directional characteristics of charged particle energy spectra in space. Specifically, this project shall procure, ground test, and deploy (on the ISS) a two-sensor TimePix detector capable of detecting protons and higher Z ions at energies from a few to >100 MeV/n; and measuring the angular dependence of detected ions.

The Miniaturized Particle Telescope (MPT) records frames of particle tracks to the SSC laptop via the REM/MRT SSC software and uses REM software already loaded on SSC. MPT improves current TimePix capability Detection of protons and higher-Z ions from a few to >100 MeV/n. The telescope resolves ion energy within a minimum of 6 bins (ground processing) and determines particle track through both sensors (ground processing). The flux spectrum within angular resolution is determined by acceptance angle of stack.

Space Applications
Miniaturized Particle Telescope technology may be used for future Exploration missions and vehicles.

Earth Applications
The Miniaturized Particle Telescope helps monitor and determine space radiation environment effects (exposure to ionizing radiation) on humans.

Operational Requirements and Protocols

The MPT operates in an identical manner as the current REM units on-board ISS. Data are downlinked daily. The detector uses the same software that is currently running the ISS REM units on the SSC. Specifically, the unit is operated as follows:
  • Two sensors operate synchronously.
  • The unit must be powered by USB connection and transfer frames to laptop for storage.
  • Software captures and writes frames to file. No onboard analysis is required by the software.
  • The unit can be tethered to laptop via USB cable.
