“…The ESA-sponsored project SATRAM (Space Application of TIMEPIXbased Radiation Monitor) uses the Timepix detector to continuously monitor space weather [55,56]. It is incorporated in the ProbaV earth monitoring satellite in a sun-synchronous orbit at an altitude of 820 km and monitors the direction and stopping power of incoming charged particles.…”

Hybrid pixel detectors were developed to meet the requirements for tracking in the inner layers at the LHC experiments. With low input capacitance per channel (10-100 fF) it is relatively straightforward to design pulse processing readout electronics with input referred noise of ∼100 e-rms and pulse shaping times consistent with tagging of events to a single LHC bunch crossing providing clean 'images' of the ionising tracks generated. In the Medipix Collaborations the same concept has been adapted to provide practically noise hit free imaging in a wide range of applications. This paper reports on the development of three generations of readout ASICs. Two distinctive streams of development can be identified: the Medipix ASICs which integrate data from multiple hits on a pixel and provide the images in the form of frames and the Timepix ASICs who aim to send as much information about individual interactions as possible off-chip for further processing. One outstanding circumstance in the use of these devices has been their numerous successful applications, thanks to a large and active community of developers and users. That process has even permitted new developments for detectors for High Energy Physics. This paper reviews the ASICs themselves and details some of the many applications.

“…The silicon pixel detector can provide unambiguous charge identification in very high multiplicity events, particularly interesting for studying strong solar particle events. A promising candidate is the Timepix (Ballabriga et al, 2018) series hybrid pixel detector, which has already been used in space for dosimetry measurements (Turecek et al, 2011) and space weather analyses (Gohl et al, 2016) . But it needs to be re-optimized for large dynamic range and low power consumption.…”

PAN is a scientific instrument suitable for deep space and interplanetary missions. It can precisely measure and monitor the flux, composition, and direction of highly penetrating particles (>∼100 MeV/nucleon) in deep space, over at least one full solar cycle ( 11 years). The science program of PAN is multiand cross-disciplinary, covering cosmic ray physics, solar physics, space weather and space travel. PAN will fill an observation gap of galactic cosmic rays in the GeV region, and provide precise information of the spectrum, composition and emission time of energetic particle originated from the Sun. The precise measurement and monitoring of the energetic particles is also a unique contribution to space weather studies. PAN will map the flux and composition of penetrating particles, which cannot be shielded effectively, precisely and continuously, providing valuable input for the assessment of the related health risk, and for the development of an adequate mitigation strategy. PAN has the potential to become a standard on-board instrument for deep space human travel.PAN is based on the proven detection principle of a magnetic spectrometer, but with novel layout and detection concept. It will adopt advanced particle detection technologies and industrial processes optimized for deep space application. The device will require limited mass ( 20 kg) and power ( 20 W) budget.Dipole magnet sectors built from high field permanent magnet Halbach arrays, instrumented in a modular fashion with high resolution silicon strip detectors, allow to reach an energy resolution better than 10% for nuclei from H to Fe at 1 GeV/n. The charge of the particle, from 1 (proton) to 26 (Iron), can be determined by scintillating detectors and silicon strip detectors, with readout ASICs of large dynamic range. Silicon pixel detectors used in a low power setting will maintain the detection capabilities for even the strongest solar events.A fast scintillator with silicon photomultiplier (SiPM) readout will provide timing information to determine the entering direction of the particle, as well as a high rate particle counter. Low noise, low power and high density ASIC will be developed to satisfy the stringent requirement of the position resolution and the power consumption of the tracker.

“…Six miniature radiation monitors are operating aboard the International Space Station since 2012 in collaboration with the University of Houston and NASA (Kroupa et al ; Stoffle et al ; Turecek et al ; Vykydal & Jakubek ). One Timepix detector is the core of the SATRAM module, developed in collaboration with CSRC Brno, onboard the ESA Proba‐V satellite since 2013 (Gohl et al ; Granja et al ). Another Timepix detector is a part of the miniaturized X‐ray telescope onboard the Czech cubesat VZLUSAT‐1 since 2017 (Baca et al ; Baca et al ; Urban et al ).…”

RISEPix—A Timepix‐based radiation monitor telescope onboard the RISESAT satellite

Rapid International Scientific Experiment Satellite (RISESAT) is a small Japanese experimental Earth-observing, science and technology demonstration satellite. One of the scientific instruments onboard is a miniature radiation monitor telescope RISEPix with two Timepix detectors, developed and built at the Institute of Experimental and Applied Physics, Czech Technical University in Prague. After its successful launch in January 2019, RISESAT joined two other still operational satellites with our Timepix-based radiation monitors, SATRAM onboard the ESA satellite Proba-V (launched in 2013) and the Czech VZLUSAT-1 cubesat (launched 2017). In this work, we present general technical and scientific details about the RIS-ESAT satellite mission and the RISEPix module, and a basic comparison of space weather monitoring from SATRAM and VZLUSAT-1 radiation monitors.
