DESY Summer Students join groups engaged in the following activities:

Program A : Experiments with Synchrotron Radiation (only at Hamburg)

  • Students join photon science groups at DESY engaged in fundamental and applied research in the fields of physics, biology, chemistry, crystallography, material science, and geological science. Some of the students will work in the frame of the European XFEL project. The work includes participation in activities like preparation and realization of measurements, evaluation of measured data, and technical improvements of instrumentation.
  • A1. Solid-state physics and nanoscience (application oriented):
    In the field of nanoscience and solid-state physics, students will get hands-on experience in growth of nanostructures ( thin films, nanoparticles) by molecular beam epitaxy and sputtering or the preparation of well-defined, ultra-clean surfaces. In addition they will be introduced to the modern nanoscience approach for the characterization of such nanostructures by combining surface sensitive X-ray diffraction methods with standard surface and nanoscience analytical tools such as scanning electron microscopy, atomic force microscopy and X-ray photoelectron spectroscopy for chemical characterization. In more theoretical projects an introduction to diffraction data analysis concepts for nanostructures and interfaces is offered.
  • A2. Molecular sciences (application oriented):
    Students join groups performing research in chemistry, biology and physics aiming at unraveling the structure-function relationship of molecular sciences. Experiments include the imaging of molecular structure and dynamics of systems ranging from small molecules over nano-objects to biological macromolecules, viruses or cells. These experiments push limits of spatial and temporal resolution using novel X-ray, electron, or ultrashort-laser-pulse sources. Projects include sample preparation, imaging experiments, and data analysis.
  • A3. Soft-matter sciences (application oriented):
    Summer students will learn about modern methods to investigate the structure and dynamics of soft matter systems such as complex liquids and glasses. The students will be introduced into small angle X-ray scattering (SAXS) using coherent X-ray beams, X-ray photon correlation spectroscopy (XPCS), and X-ray cross-correlation analysis (XCCA). In addition, they will be taught how to synthesize colloidal samples in our chemistry lab. Hands on experiments can be performed using laser scattering set-ups to practice the learnt methods on self-synthesized colloidal systems. Analyzing and interpreting the obtained data allows both to train their programming skills as well as the critical discussion of experimental results.
  • A4. Development of experimental techniques (methodology oriented):
    Students join groups developing new experimental techniques in the field of photon science, including diffraction and scattering, spectroscopy, and imaging. X-rays have unique properties to probe matter on all length scales down to the atomic level. The large penetration depth gives access to the bulk of a sample, and allows the investigation of a specimen inside special sample environments, such as chemical reactors or pressure cells. Topics include ultrafast, time-resolved or in-situ diffraction and scattering techniques, imaging and microscopy with coherent X-rays, tomography, X-ray optics and nanofocusing, scanning microscopy and microspectroscopy.
  • A5. Lasers and optics (methodology oriented):
    Students join groups in developing laser sources, measurement and diagnostics techniques and their applications. Topics are ultrafast lasers, high power and high energy lasers, fiber and waveguide lasers, optical parametric chirped pulse amplifiers, optical pump- XUV probe experiments, free-electron laser (FEL) seeding, strong field optical sub-cycle pulse synthesis, mid-infrared sources, frequency combs and phase stable laser sources, laser spectroscopy, dielectric accelerators, low emittance photoelectron generation, strong field THz pulses for time resolved studies, X-ray pulse diagnostics and compact THz accelerators, high order harmonic generation and attosecond science, ultrafast nano-optics, and compact X-ray sources. Projects include laser optics, optomechanics, electronics and programming, simulations and data analysis.
  • A6. Theory and computing:
    Theory problems addressed in photon science generally have a close connection to experimental applications or to the development of new methodologies for characterizing the properties of matter. Most problems of interest require an intense use of numerical techniques, but also a solid understanding of the underlying theory. Projects for summer students include work on solving the Schrödinger equation for highly excited many-electron systems; solving the time-dependent Schrödinger equation for the description of dynamical processes; techniques for nonperturbative radiation-matter interactions; quantum-chemical simulations; and the development of algorithms for solving mathematical problems specific to photon science and imaging science.

Program B : Research in Elementary Particle and Astroparticle Physics, accelerators and computing:

  • Experiments in Elementary Particle and Astroparticle Physics
    Research is concentrated on the following areas:
    -- the experiments ATLAS, CMS at the proton-proton-collider LHC,
    -- the preparations for experiments at the e+e- International Linear Collider,
    -- the Belle II experiment and
    -- the experiment ALPS II at DESY.
    -- At Zeuthen research is done also on the areas
    • gamma-ray astronomy and astroparticle physics with the observatories
      CTA, HESS, MAGIC, VERITAS, and Fermi LA (Zeuthen site only) and
    • neutrino astronomy and astroparticle physics with the
      IceCube Observatory (Zeuthen site only).
    The activities can be characterized by the following categories :
  • B1 Physics analysis (software-oriented)
  • B2 Data processing (software-oriented)
  • B3 Development of experimental equipment (hardware-oriented)
  • B4 Research on Accelerators
    Students join groups engaged in the development of accelerators. Activities include prototype projects for an e+e- linear collider with an emphasis on superconducting rf cavities and projects for beamline instrumentation and plasma wakefield acceleration. In Zeuthen students can actively participate in the development of the photo injector test facility PITZ.

  • B5. Theory of Elementary Particles and Astroparticle Physics
    Students acquire some elementary insight into topics from the wide spectrum of research carried out in Hamburg at the DESY Hamburg theory group and in Zeuthen at the DESY Zeuthen theory group, the NIC institute and the Astroparticle Physics theory group . Depending on previous knowledge, activities typically range from further reading, with discussions of theoretical concepts and research methods, to participation in simple research projects. Students are encouraged to indicate in their application if they have a preference for a particular field of research pursued in the theory groups. Often at least a minimum pre-knowledge (e.g. from lecture courses) is required in order to be selected for a project in a particular field.

  • B6. Computing
    At DESY Hamburg students can participate in various areas of scientific computing such as Grid and Cloud, data management (dCache), high performance (HPC) and GPU, and in infrastructures for analysis. At Zeuthen students participate also in tests and software development for powerful parallel computers

  • Typical fractions of the number of offered projects in the different areas are:
    B1(30%), B2(8%), B3(36%), B4(12%), B5(10%) and B6(4%).

In the online application: please mark for which program categories you apply (up to three choices), examples:
- you mark A1, A4, A5 as your choices
- you mark B1, B5, B3 as your choices.
Please take note:
- Mixed choices like A1, B2 are not possible
- Since the number of available places are very different in the subcatagories your first choice may not be realized.
