Characterization of THz Radiation


To optimize the user operation with THz coherent synchrotron radiation at the ANKA storage ring, a detailed understanding of the radiation characteristics as a function of the operating conditions of the accelerator is of vital importance.


  1. •Investigation of coherent synchrotron radiation with fast THz-detectors

Accelerator Optics and Beam Dynamics


The setup of the magnets in the storage ring is called the accelerator optics. The simulation of the beam dynamics for a given optics and its comparison to measurements is a central point of our research.


  1. •Design of magnet optics for creating ultra-short electron bunches

  2. •Halo and Tail Generation

  3. •Enhancing the Control System

  4. •Energy Calibration with Resonant Depolarisation

Measurement of Bunch Length and Current Distribution


Various effects in the storage ring can influence the bunch length and shape. To study these, different detector systems are in use or being developed.
An image by a streak camera, for example, is shown on the right.


  1. •Bunch length measurement with two photon absorption in LEDs

Single- and Multi-Bunch Effects


Interactions within a bunch and between bunches can excite instabilities that influence the generation of THz radiation. This is being investigated with a new electron source (installation 2009) and an ultra-fast hot electron bolometer.
