    IMPS is not yet commissioned.

    First tests in 2008 gave promising results.

    Test sample: Germanium

    First measurement: Ge 

    Phonons measured on the dispersive mode:

    • constant q scans
    • 9 blades at constant kf = 2.662 Å-1
    • ~ 6 min/point
    • Phonons on the ~[111] direction
