We are currently developing a Multiline Spectrometer to be installed at the Vacuum Tower Telescope (VTT) at Izana, Tenerife. It will be used to investigate the propagation of waves throughout the solar atmosphere and to analyze how this propagation is influenced by magnetic fields and activity regions.
The Double-Etalon Fabry-Perot System is used in a Collimated-Beam Configuration with a field of view of 100” by 100”. The theoretical resolution limit is 0.2”. Data are recorded with a DALSA 1M30 CCD-Camera.

We carried out a first test of the new system at the VTT in July 2009. We have observed 16 spectral lines simultaneously at a cadence of 1 Min. Besides oscillatory phenomena we also hope to investigate in the future impulsive events in the upper Atmosphere at a previously unattained height resolution.
