Abstract [en]

EUSO-TA is a ground-based telescope, installed at the Telescope Array (TA) site in Black Rock Mesa, Utah, USA. This is the first detector to successfully use a Fresnel lens based optical system and multi-anode photomultipliers (64 channels per tube, 2304 channels encompassing a 10.6° × 10.6° field of view) for detection of Ultra High Energy Cosmic Rays (UHECR). The telescope is located in front of one of the fluorescence detectors of the TA experiment. Since its installation in 2013, the detector has observed several ultra-high energy cosmic ray events and, in addition, meteors. The limiting magnitude of 5.5 on summed frames (∼ 3 ms) has been established. Measurements of the UV night sky emission in different conditions and moon phases and positions have been completed. The performed observations serve as a proof of concept for the future application of this detector technology.

Abstract [en]

JEM-EUSO is a space mission designed to investigate Ultra-High Energy Cosmic Rays and Neutrinos (E > 5.10(19) eV) from the International Space Station (ISS). Looking down from above its wide angle telescope is able to observe their air showers and collect such data from a very wide area. Highly specific trigger algorithms are needed to drastically reduce the data load in the presence of both atmospheric and human activity related background light, yet retain the rare cosmic ray events recorded in the telescope. We report the performance in offline testing of the first level trigger algorithm on data from JEM-EUSO prototypes and laboratory measurements observing different light sources: data taken during a high altitude balloon flight over Canada, laser pulses observed from the ground traversing the real atmosphere, and model landscapes reproducing realistic aspect ratios and light conditions as would be seen from the ISS itself. The first level trigger logic successfully kept the trigger rate within the permissible bounds when challenged with artificially produced as well as naturally encountered night sky background fluctuations and while retaining events with general air-shower characteristics.

Abstract [en]

The Association of Space Explorers (ASE) organizes the annual "ASE Planetary Congress". This year (2015) between 20-27 September, the congress took place in Sweden, with the theme name Inspired by Space. In addition to give astronauts and cosmonauts from all over the world a forum to meet and discuss, there are several open technical sessions with a mixture of speakers by ASE members and distinguished guests. However, the most important part of the Planetary Congresses are the "Community Days", when the participating astronauts and cosmonauts split in small groups and visit schools, universities, and other public places. In Sweden about one hundred astronauts were expected to participate and during two half-days around close to hundred schools would get visits by space fliers who share their experiences and enthusiasm with many thousands of pupils and students. The schools prepare many months in advance for the visits, e.g. by "challenges" that are published on websites. Teachers are invited to special briefings. This talk will present the preparations for the ASE congress Inspired by Space Community Days that were done in order to optimize the impact of visiting astronauts and cosmonauts, and detail the outcome, which took place only a few weeks before IAC2015. The presenter is the head responsible for the Inspired by Space congress.

Abstract [en]

In this work we present data on linear energy transfer (LET), dose and dose equivalent rates from different locations of the Russian part of the International Space Station (ISS) measured by the Sileye-3/Alteino detector. Data were taken as part of the ESA ALTCRISS project from late 2005 through 2007. The LET rate data shows a heavy-ion (LET > 50 keV/mu m) anisotropy. From the heavy-ion LET rate in the Zvezda service module we find ISS (y) over cap (Starboard) and (z) over cap (Nadir) to be about 10-15 times higher than in (x) over cap (Forward). The situation is similar for dose and dose equivalent rates, ranging from 25-40 mu Gy d(-1) in (x) over cap to about 75 mu Gy d(-1) in (z) over cap, whereas for the dose equivalent the rate peaks in (y) over cap with around 470 mu Sv d(-1). The heavy-ion anisotropy confirms what has been reported by the ALTEA collaboration. Measurements using two sets of passive detectors, DLR-TLDs and PADLES (TLD+CR-39), have also been performed in conjunction with Alteino measurements, both shielded and unshielded. The passive detectors register a dose rate about 3-5 times as high as Alteino, 260-280 mu Gy d(-1) for PADLES and 200-260 mu Gy d(-1) for DLR-TLDs. For the dose equivalent PADLES measurements ranges from 560-740 mu Sv d(-1).

Abstract [en]

The Mini-EUSO (Extreme Universe Space Observatory) is a small UV telescope to be placed inside the Zvezda module of ISS in 2017, as a part of the work of the JEM-EUSO collaboration. The Mini-EUSO instrument will be equipped with one full original JEM-EUSO Photo-Detector-Module (PDM), an optical system made of two Fresnel lenses (25 cm in diameter) and a data acquisition system. The Mini-EUSO instrument serves as a pathfinder towards the goals of the full JEM-EUSO mission: to place a large instrument on the outside of ISS to study Ultra-High Energy Cosmic Rays (UHECR) with energies of E > 3×1019 eV. This can be achieved by measuring the light in the UV range from the Extensive Air Showers (EAS) that these particles trigger in the atmosphere [1]. By using the ISS altitude to monitor a target volume far greater than is possible from the ground, unprecedented statistical accuracy of the primary energy, arrival direction and composition of UHECRs will be obtained. Such data will shed light on the origin of the UHECRs, on the sources that are producing them, on the propagation environment from the source to the Earth and, possibly, on the particle physics mechanisms at energies well beyond those achievable in man-made accelerators. Moreover, there are exploratory objectives such as constraining the galactic and extragalactic magnetic fields, the detection of extreme energy neutrinos and gamma rays, the verification of special relativity at extremely large Lorentz factors, the examination of possible quantum gravity effects at extreme energies and the systematic surveillance of atmospheric phenomena. The Mini-EUSO instrument will have 2, 304 pixels from 36 multi-anode PMTs with each pixel viewing an equivalent area of 5.4 × 5.4 km2 on ground. The full field of view is ±19° and the instrument has a time resolution of 2.5 μs. The Mini-EUSO mission has at least four different objectives: (1) to raise the technical readiness level of JEM-EUSO to the highest grade, (2) to perform an absolute calibration of the multi-anode photomultipliers in flight (crucial for JEM-EUSO), (3) to take advantage of being at ISS altitude, like JEM-EUSO, and study in a precise way the UV background coming from Earth in all the different reflective conditions (water, earth, vegetation, snow, etc.) and (4) to study atmospheric phenomena, such as lightning, and related light, as well as meteors.

Abstract [en]

The development of the GAMMA-400 γ-ray telescope continues. The GAMMA-400 is designed to measure fluxes of γ-rays and the electron-positron cosmic-ray component possibly associated with annihilation or decay of dark matter particles; and to search for and study in detail discrete γ-ray sources, to measure the energy spectra of Galactic and extragalactic diffuse γ-rays, and to study γ-ray bursts and γ-rays from the active Sun. The energy range for measuring γ-rays and electrons (positrons) is from 100 MeV to 3000 GeV. For 100-GeV γ-rays, the γ-ray telescope has an angular resolution of ∼0.01°, an energy resolution of ∼1%, and a proton rejection factor of ∼5 × 105. The GAMMA-400 will be installed onboard the Russian Space Observatory.

Abstract [en]

In this work we present data from the Sileye-3/Alteino detector on board the International Space Station (ISS), which was gathered following a recalibration after several years in orbit. We also measure the relative nuclei abundance and integrated flux, which were normalized to the solar modulation values of August 2007. The measurements were made at different locations of the Russian part of the ISS. The relative nuclear abundances of C to Fe in relation to C, in an energy range above similar or equal to 60 MeV/n, shows high levels of odd Z particles inside the ISS and an under-abundance of C and O compared with the galactic spectrum, as presented by Simpson in 1983. In addition, the values of the integrated flux varies primarily according to location and detector orientation. An additional polyethylene shield also reduces the flux, although in a lower amount than changes in the orientation of the telescope. Data were taken as part of the ESA ALTCRISS project from late 2005 through to 2007.

Abstract [en]

In December 2006 I took part in the STS-116 mission, during the assembly of ISS. Being the first Scandinavian in space, it created a lot of interest in my home country Sweden. In various ways that were, and still are, exploited to inspire young people - from primary school pupils to university students - to become interested in STEM subjects, or even to go for a master education in aerospace engineering. A second shuttle flight in 2009 reinforced the interest and opened new outreach possibilities. To achieve optimal outreach during a space mission - in particular comparatively short ones such as shuttle missions - early and detailed planning is crucial. With favorable conditions the potential for post-flight exploitation of astronauts to inspire the young is huge, but smart selections are necessary. For example, there is no limit in how many schools could be visited, but that is probably not the best use of limited time. I have visited most Swedish universities and some schools, but now with the Swedish National Space Board a couple of dedicated school tours per year, of about a week each, targeting different geographical areas are being organized. On a higher level, I was appointed to a government committee that was tasked to propose actions to increase the number of students in STEM subject. Partly to increase the attractiveness of a master program in aerospace engineering, I've been asked to be in charge of it and I'm developing a dedicated course "Human Spaceflight" within the program. Another way to create interest among the youngest ones is through children’s books about space. I've written four books about two siblings that travel in space with their uncle Albert. The stories are meant to be entertaining and exciting and involve physics, mathematics, and other sciences. These books then act by themselves to stimulate children to think about space and science in various ways. Last year a campaign "talk-to-space" was introduced It encouraged children to formulate questions they would like to ask an extraterrestrial. Earlier we arranged a mathematics challenge.

Abstract [en]

Over the years many devices, using different technologies and various locations, have been used - and are still in use - on the International Space Station, ISS, to measure and map the radiation and cosmic particle flux which astronauts as well as sensitive electronics are exposed to. This presentation presents recent analyses and results from the SilEye-3/Alteino detector during the ESA-sponsored project ALTCRISS. Comparisons are made with data from other experiments, such as ALTEA and PADLES. Alteino is a Si-strip detector, developed from the two SilEye detectors that were operated on Mir, in particular for studies of the Light Flash phenomena. Alteino was used at several locations, and orientations, in the Russian segment of ISS from late 2005 through 2007. Many of the data sets were obtained with a shielding of 5 g/cm2 polyethylene in front of the detector. Data on nuclei from C to Fe in the energy range above ≃  60 MeV/n show an increase in relative abundance for odd Z inside ISS compared to the outside, due to fragmentation in the hull. Fluxes and relative abundances vary with location and shielding, where the material of the station itself plays a major role. The difference in flux can be as much as 50%. LET spectra - which are not restricted to single particle events - show similar tendencies, though when converted to equivalent dose rates the effect of the polyethylene is somewhat pronounced. Comparison with ALTEA data shows slightly higher dose rates for Alteino in the Russian segment, which can be expected due to that ALTEA operated in the US lab Destiny with more station material around it. As expected, the response of CR39 in terms of equivalent dose rate is higher than Alteino, due to the smaller acceptance energy range of the latter.
