Online Burst Analysis of Coherent THz Radiation at ANKA — •Miriam Brosi1, Michele Caselle4, Edmund Hertle3, Vitali Judin2, Anke-Susanne Müller1,2,3, Nigel Smale2, and Johannes Steinmann1 — 1LAS, KIT, Karlsruhe — 2ANKA, KIT, Karlsruhe — 3IPS, KIT, Karlsruhe — 4IPE, KIT, Karlsruhe
ANKA, the synchrotron light source in Karlsruhe, provides a low-alpha operation mode for users. In this mode, coherent synchrotron radiation (CSR), which is emitted by short bunches, can be provided up to a frequency of several THz. Bursts in the CSR intensity, driven by instabilities in the longitudinal phase space and bunch length fluctuations, have been measured for single and, recently, multi bunch operation. Providing coherent THz radiation for users on a reliable and controlled basis requires better understanding of these time dependent fluctuations. Therefore, ultra fast THz detectors together with an FPGA-based DAQ system are developed in collaboration with IPE and IMS at KIT.
Tools are being developed and optimized to characterize and further understand the bursting behavior for different storage ring parameters and to investigate phase, correlations and interaction between the bursting of different bunches. In this contribution the first results are presented and an outlook towards an online data analysis system is given.
