Master Laboratory Applied Physics

MasterLabBanner.JPG

 

General information

The Master Lab Applied Physics is integral part of the M.Sc. program "Applied Physics" and is designed to provide insight into the various research topics in Applied Physics conducted at the University of Freiburg and the affiliated research institutes. It represents the ideal orientation for the choice of the final master research topic.

The Master Laboratory Applied Physics consists of the successful accomplishment of different laboratory experiments. For each experiment, students prepare a written report, which is part of the final assessment.

For each of the experiments a grade is given based on an initial written and oral questioning (test of the preparatory knowledge), the experimental performance and the written report (incl. lab report and analysis). All marks contribute to the final module grade (weighted mean).

 

Organization

In an initial meeting the students will be informed about the internal regulations and the organization of the lab:

Tuesday, 10. Jan 2017
16:00
in seminar room Gustav-Mie building

 

Students have to select 6 experiments from a list of offered lab experiments. Each experiment is typically performed in teams of two students. They arrange date and time for the individual experiment with the responsible contact persons. Students should download and use the following marked score card to document progress and performance (mark for all experiments):


After successful accomplishment of all 6 experiments the score card has to be handed in at the examination office.

 

List of experiments

 

  • Exp 1 - MR Imaging: Contrasts and Methods
    Responsible/contact person: Prof. Dr. M. Bock, Universitäts Klinikum
    Location:

    Duration: 2 days
    Next availibility:  Jan - March 2017

    In this practical course the students will be introduced to the usage of a clinical high field MRI system. A phantom will be constructed, and the relaxation time T1 of different solutions will be measured. In a volunteer experiment, MR image contrasts and imaging methods will be demonstrated and assessed systematically.

  • Exp 2 - Infrared Spectroscopy for Analytical Applications
    Responsible/contact person: Dr. F. Kühnemann, Fraunhofer Institute for Physical Measurement Techniques (IPM)
    Location: Fraunhofer IPM, Heidenhofstraße 8, 79110 Freiburg

    Duration: 2 days
    Next availability: starting in Jan. 2017

    In this experiment, the students will be introduced to the use of infrared spectroscopic techniques for analytical applications. Examples are absorption measurements of atmospheric gases and the characterization of liquids and solids.

     

  • Exp 3 - Light Scattering of Colloidal Crystals
    Responsible/contact person: Prof. Dr. G. Reiter, Physikalisches Institut
    Location: Physics highrise building, 3rd floor

    Duration: 2 days
    Next availability: starting April 2017

    The scattering of light by polycrystalline samples of spherical colloids is studied using the Debye-Scherrer technique. Several lasers with different wave-lengths are employed to increase the number of detectable reflections.

     

  • Exp 4 - Crystal Growth from the Melt
    Responsible/contact person: PD Dr. A. Danilewsky, Kristallographisches Institut
    Location: Kristallographisches Inst., Hermann-Herder Str. 5, 3rd floor

    Duration: 2 days
    Next availability: starting Jan 2017 (Mo and Tue)

    The students will grow their own crystals from the melt by the Czochralski method. They will experience, how sensitive heat flows, pulling and rotation speed influence the quality of the growing crystal during seeding, necking and steady state growth. The system NaNO3 allows the direct observation by eye and acts as a model system for the industrially important growth method for e.g. silicon or GaAs.

     

  • Exp 5 - Measuring the rotation of the Sun
    Responsible/contact person: Prof. Dr. Wolfgang Schmidt, Kiepenheuer-Institut für Sonnenphysik
    Location: Solar Observatory, Schauinsland

    Duration: 2 days
    Next availability:  Introduction meeting on Mi 03.05.2017 in SR I

    In this course the students will learn how to operate a solar telescope and a spectrograph with high spectral resolution. The differential rotation of the Sun will be measured using the Doppler effect. In a second part, solar rotation will be determined from the apparent motion of sunspots across the solar disk.

     

  • Exp 6 - Atomic Force Microscopy (AFM)
    Responsible/contact person: Prof. Dr. G. Reiter, Physikalisches Institut
    Location: Physics highrise building, 3rd floor

    Duration: 2 days
    Next availability: starting April 2017

     

  • Exp 7 - Solid State Laser
    Responsible/contact person: Prof. Dr. Frank Stienkemeier, Physikalisches Institut
    Location: Physics highrise building, -1 floor

    Duration: 2 days
    Next availability: starting April 2017

     

  • further experiments will be available in the upcoming semesters
