    physics719 BCGS intensive week (Test beam measurements with a pixel telescope at the DESY electron test beam)
    September/October 2020
      Instructor(s): I. Gregor
      Prerequisites: Basic knowledge of particle physics at the bachelor or master level is assumed.
    Some programming knowledge (C or C++) would
    also be very useful but are not mandatory.
      Contents: This course will be of interest for students starting their master studies,
    students who start their master project soon, and Ph.D. students
    from other fields of physics who wish to broaden their horizon. We will discuss
    particle detectors as mostly used in particle physics with focus
    on silicon tracking detectors. In the afternoons tests with a pixel telescope
    will be performed at the DESY test beam and the obtained data
    analysed. An overview of important parameters for detector testing will be given
    and some of them tested in laboratory tests. This course will
    be at DESY in Hamburg (travel costs will be covered)!!

    While following these lines, particular emphasis is given to

    - Overview on detectors for particle physics
    - Passage of particles through matter
    - Basics on tracking detectors with focus on 
semi-conductor detectors
    - Reconstruction of hits
    - Important parameters for detector testing and 
how to measure those
    - Radiation damage effects
    - Simulation of tracks
    - Taking data with a pixel telescope (electrons at DESY test beam)
    - Test beam data analysis

    Of course, not all topics can be addressed to depth within one week. Thus,
    an effort is made that students will receive an overview and
    understand the most important concepts. The course is an all-day seminar
    starting on Monday morning of the selected week.

    Registration: To take part please register on eCampus:
    https://ecampus.uni-bonn.de/goto_ecampus_crs_1861366.html


    before the end of December 2020.

    Students who wish to receive course credits also need to register on
    BASIS!


    Registrations opens on November 1st 2021 until end of January 2021. If the
    Corona situation does not allow an in-person course at DESY, an all-
    online course will be offered in the same week.

    Form of Testing and Examination: Seminar talk. Students who would like to obtain
    course credit for the intensive week give a seminar talk during
    or after the intensive week. Please contact gregor@physik.uni-bonn.de as soon as
    you registered if you would like to give a presentation. The
    course can also be taken without course credit.

      Literature: Will be provided.
      Comments: The course is an all-day workshop in the lecture free time (February or March
    2021).

    The Intensive Week will have lectures in the morning and hands-on exercises in
    the afternoon.
