Eggenstein-Leopoldshafen

Neureut is the northernmost borough (German: Stadtteil) of the German city of Karlsruhe. It was the most populous rural community of Baden-Württemberg before being incorporated into Karlsruhe on 14 February 1975. Its population is about 18,900 people as of December 2020.

Forschungsreaktor 2 (FR2) (Research Reactor 2) was the second nuclear reactor built in and by Germany after restrictions on nuclear research imposed as a result of the Second World War were lifted in 1955. Construction began in 1957 in Eggenstein-Leopoldshafen/BW. The organization charged with the project evolved into the Kernforschungszentrum Karlsruhe (KfK) (Karlsruhe Nuclear Research Centre), which in turn evolved into the present day Karlsruhe Institute of Technology (KIT). FR2 started up on December 12, 1962, and ceased operation in December 1981. As of 2005, the reactor core is contained, and the auxiliary buildings have been demolished or are being used for non-nuclear research activities, mostly in micro process engineering, which uses manufacturing technologies that originated from mechanical microstructuring processes that had been developed in the context of nuclear technologies (isotope separation).

The Hardtwald is a forest in Baden-Württemberg, south-western Germany. It is located around Karlsruhe, on the right (eastern) bank of the Rhine, between Schwetzingen in the north and Rastatt in the south. The Black Forest is located to its east. In the 18th century, Karlsruhe was founded in the Hardtwald.

ANKA (abbreviation for „Angströmquelle Karlsruhe“) is a synchrotron light source facility at the Karlsruhe Institute of Technology (KIT). The KIT runs ANKA as a national synchrotron light source and as a large scale user facility for the international science community. Being a large scale machine of the performance category LK II of the Helmholtz Association (Helmholtz Association of German Research Centres), ANKA is part of a national and European infrastructure offering research services to scientific and commercial users for their purposes in research and development. The facility was opened to external users in 2003.

The Alb is a river in the Northern Black Forest in Germany. It is a tributary of the Rhine, and flows through the cities of Karlsruhe, Ettlingen and Bad Herrenalb.

The Institut für Nukleare Entsorgung (English: Institute for Nuclear Waste Disposal) is a large German research center at Karlsruhe Institute of Technology where R&D in the field of safe disposal of nuclear waste is being provided. It is located 1 kilometre (0.62 mi) east of Linkenheim-Hochstetten.

KATRIN is a German acronym (Karlsruhe Tritium Neutrino Experiment) for an undertaking to measure the mass of the electron antineutrino with sub-eV precision by examining the spectrum of electrons emitted from the beta decay of tritium. The experiment is a recognized CERN experiment (RE14). The core of the apparatus is a 200-ton spectrometer. In 2015, the commissioning measurements on this spectrometer were completed, successfully verifying its basic vacuum, transmission and background properties. The experiment began running tests in October 2016. The inauguration took place 11 June 2018, with the first tritium measurements by the experiment (the so-called First Tritium or FT 2-week engineering run in mid-2018). The projected experiment duration at the time was 5 years. The first science measurements (so-called first campaign) took place 10 April 2019.In February 2022, the experiment announced an upper limit of mν < 0.8 eV c–2 at 90% confidence level.

The LOPES project (LOFAR PrototypE Station) was a cosmic ray detector array, located in Karlsruhe, Germany, and is operated in coincidence with an existing, well calibrated air shower experiment called KASCADE. In 2013, after approximately 10 years of measurements, LOPES was finally switched off and dismantled. There are different ways to observe cosmic rays, or, more accurately, the air showers that cosmic rays produce when they enter our atmosphere. Traditionally, one directly measures the shower products that make it all the way to the surface. These may be detected by using for example particle counters. In the case of KASCADE, the muons in the shower produce a short flash of Cherenkov light when they traverse a slab of scintillator material. These flashes can be registered using photomultipliers. The LOPES project aims to demonstrate the feasibility of a different technique, in which not the shower products themselves are observed, but secondary radio radiation that is generated by the shower. Charged particles in the shower, mostly electrons and positrons, are deflected slightly in Earth's magnetic field. As these particles change direction, they emit synchrotron radiation. This radiation is visible as a bright flash on the sky for several nanoseconds at frequencies up to a few hundred MHz. It is hoped that the LOPES project will pave the way for more cosmic ray experiments with digital radio telescopes, such as LOFAR. In the first phase until 2003, LOPES consisted of ten dipole antennas. This has been expanded to a total number of 30 antennas as of summer 2005. These antennas are read out digitally and are connected to a central computer. Here, the data from the antennas is correlated by software, so that the antennas together essentially form a phased array. The software can point the array by forming a virtual beam and is also able to adaptively suppress interference from other sources, such as radio and TV stations. The test array was first set up at the MPIfR in Bonn to check the hardware and develop the software. Afterwards it has been installed at the KASCADE experiment in Karlsruhe. This is a running and well calibrated air shower experiment, which provides LOPES with a suitable trigger and reconstructed shower parameters. These parameters will act as a starting point for LOPES and have been used to calibrate its results. In a second phase starting 2006, 15 antennas have been rotated by 90° to measure the polarization of the radio signal emitted by air showers. This efforts have been intensified in the third and last phase of LOPES starting 2010, when 10 new antenna stations were installed which allow to measure the complete polarization at each station. After leading to many scientific results published in various journals, LOPES has finally been switched off in 2013. LOPES is a collaboration of ASTRON (Netherlands Foundation for Research in Astronomy, Dwingeloo, The Netherlands), the Max-Planck-Institut für Radioastronomie (Bonn, Germany), Radboud University (Nijmegen, The Netherlands), the Institute of Data Processing and Electronics (IPE) and the Institut für Kernphysik (IKP), both at the Karlsruhe Institute of Technology (Karlsruhe, Germany), and the KASCADE-Grande collaboration. The KASCADE-Grande collaboration consists of groups from Germany, Poland, Romania, and Italy.

KASCADE was a European physics experiment started in 1996 at Forschungszentrum Karlsruhe, Germany (now Karlsruher Institut für Technologie), an extensive air shower experiment array to study the cosmic ray primary composition and the hadronic interactions, measuring simultaneously the electronic, muonic and hadronic components. KASCADE-Grande was a further extension of the previous project by reassembling 37 detectors of the former EAS-TOP experiment running between 1987 and 2000 at Campo Imperatore, Gran Sasso Laboratories, Italy. By this Grande extension of KASCADE the energy range was extended to 1014–1018 eV. The experiment contributed significantly to the development of the CORSIKA simulation program which is use heavily in astroparticle physics. Co-located with KASCADE-Grande is the LOPES experiment. LOPES consists of radio antennas and measures the radio emission of extensive air showers. KASCADE (including all extensions) stopped operation in 2013, but a part of the detectors is still used in other experiments for cosmic-ray air showers, e.g., LOFAR or Tunka. The data acquired by KASCADE-Grande has meanwhile been made accessible to the public in the KASCADE Cosmic-Ray Data Center (KCDC).

Linkenheim-Hochstetten (German pronunciation: [ˈlɪŋkŋ̍haɪ̯m ˈhoːxˌʃtɛtn̩]) is a municipality in the district of Karlsruhe, Baden-Württemberg, Germany. It is situated on the right bank of the Rhine, 17 km north of Karlsruhe.

Seven stops are served, at Linkenheim Süd, Linkenheim Friedrichstrasse, Linkenheim Rathaus, Linkenheim Schulzentrum, Hochstetten Grenzstrasse, Hochstetten Altenheim and Hochstetten.
