Thesis: Development of a new type of Atmospheric Cherenkov Detector and Measurements of High Energy Cosmic Rays between 15 and 1000 TeV Degree of Diplomphysik (comparable to a Master of Science in Physics), University of Munich, Germany Hochschule für Philosophie S. J., (University for Philosopy) Munich, Germany, Baccalaureate in Philosophy, Research present University of Wisconsin-Madison Assistant Professor of Physics Supervise the AMANDA-II data analysis: Presently four neutrinos per day on line. Analysis in progress at UW under my supervision. Supervise the AMANDA data analysis: I presented the first observation of high energy neutrinos with the AMANDA 10 string array at the 1999 International Conference for Weak Interaction and Neutrinos in Cape Town, South Africa. Since then the UW AMANDA group was able to improve the efficiency for neutrinos by more than a factor of 10 and has now identified 200 neutrinos in a time period of 6 months, which provides the basis for a series of publications. This progress was published in a Letter to Nature and in Phys. Rev. D. Responsible for AMANDA muon neutrino analysis publication. Responsible for Monte-Carlo simulation of photon tracking and event detection. Level 2 lead for IceCube Instrumentation. There are three level 2 leads total. In this function I am responsible for overall design, construction and budget of all detector hardware and the data acquisition. Level 3 lead for Ice-Cube In-Ice Devices (strings and sensors): Responsible for the technology design and the budget of the hardware instrumentation of IceCube. 1

2 University of Wisconsin - Madison, WI, USA Assistant Scientist Area of Research: High energy neutrino astronomy In Madison I am responsible for the data analysis as well as for a major part of the construction and project management of the AMANDA experiment, the Antarctic Muon And Neutrino Detector Array. My tasks are: Coordination of the data analysis in our group of five graduate students, 6 undergraduate students and two postdoctoral scientists. With the completion of the 10 string AMANDA-B detector we began to study atmospheric muons and develop methods of background rejection. This lead to the first observation of neutrinos with the 10 string array. Simulation of photon transport and detection, a fast Monte-Carlo package of photon tracking and detection. The package is a substantial part of the standard AMANDA Monte-Carlo simulation. Optical Module design development. I continued the development work of analog optical fiber technology that I initiated at DESY. Supervision of the construction and the calibration of optical modules at the Physical Sciences Laboratory. The PMT production for AMANDA strings 5-19 took place at UW. Responsibility for the final design, the quality control and initial calibration of the optical module mass production. Preparation of the detector strings and their deployment in the ice. Responsibility for the Deployment procedure. Field Team Leadership and responsibility for string deployments at the South Pole. Coordination of the development of the drilling electronics and drill software. The drill electronics has been built at UW. Due to my experience with the drill system at the South Pole I became the point of contact between the drill company and the drill software development group at UW DESY (Deutsches Elektronen-Synchrotron), Zeuthen, Germany. Post-doctoral Research Area of Research: Experimental High Energy Neutrino Astrophysics. At DESY I performed experimental work, as well as Monte-Carlo simulation and data analysis, for both the Lake Baikal neutrino telescope and for AMANDA, the Antarctic Muon And Neutrino Detector Array. I took part in expeditions to the experimental sites at Lake Baikal and the South Pole. In the Lake Baikal experiment I was responsible for a laser calibration experiment in the lake, the purpose of which was to determine the optical properties of the water in Lake Baikal. The larger part of my work was devoted to the AMANDA experiment. For AMANDA I worked on calibration techniques with special light sources for green and UV light. I contributed to the construction of the optical sensors as well as to the deployment of these modules in the Antarctic ice. For future applications I developed a new type of analog optical fiber transmission. This type of signal transmission has been installed on all AMANDA-II sensors. For both experiments I developed a fast Monte-Carlo-Simulation package to simulate the photon scattering in ice or water, respectively Max-Planck-Institute for Physics, Munich, Germany Doctoral Research assistant 2

3 Area of Research: Development of a new type of atmospheric Cherenkov detector, Gammaastronomy and high energy cosmic rays. I developed a new type of Atmospheric Cherenkov array, named AIROBICC (AIR shower Observation By Angle Integrating Cherenkov Counters). The detector consists of 49 detector stations. I designed the optical mirror system and contributed decisively to the electronic design and the data acquisition system. The design and the performance of the AIROBICC experiment are very successful, and superior to conventional scintillator arrays. I analyzed the data and developed an efficient method for separation of gamma and hadron induced air showers. The angular resolution is an order of magnitude better (<0.1 degree) than in any other detector at comparable energy. Upper limits on cosmic point sources were obtained. Also upper limits to the isotropic component of gamma rays in the cosmic rays in the range of 50 to 100 TeV were obtained, which ruled out certain scenarios of cosmic strings as a source of highest energy cosmic rays.
