| MOPRO063 | Studies of Bursting CSR in Multi-bunch Operation at the ANKA Storage Ring | 225 |
|
||
| The ANKA storage ring can generate brilliant coherent synchrotron radiation (CSR) in the THz range due to a dedi- cated low-αc -optics with reduced bunch lengths. At higher electron currents the radiation is not stable, but occurs in powerful bursts caused by micro-bunching instabilities. This intense THz radiation is very attractive for users. However, the reproducibility of the experimental conditions is very low due to those power fluctuations. Systematic studies of bursting CSR in multi-bunch operation were performed with fast THz detectors at ANKA using a dedicated, ultra-fast DAQ-FPGA board. The technique and preliminary results of these studies are presented in this paper. | ||

| WEPRO036 | Construction and First Magnetic Field Test of a Superconducting Transversal Gradient Undulator for the Laser Wakefield Accelerator in Jena. | 2022 |
|
||
|
Funding: This work is funded by the German Federal Ministry for Education and Research under contract no. 05K10VK2 and 05K10SJ2. A superconducting transversal gradient undulator (TGU), tailored to the particular beam properties of the laser wakefield accelerator (LWFA) at the University of Jena, has been designed and constructed at KIT. This undulator in combination with a specialized beam transport line will be employed to produce undulator radiation with natural bandwidth despite the relatively large energy spread of the electrons produced by the LWFA. The fabrication of this undulator and first results of the magnetic field measurement are discussed in this paper. |

| THPME113 | Commissioning of an Ultra-fast Data Acquisition System for Coherent Synchrotron Radiation Detection | 3497 |
|
||
| The commissioning of a new real-time and high-accuracy data acquisition system suitable for recording individual ultra-short coherent pulses detected by fast terahertz detectors will be presented. The system is able to monitor turn-by-turn all buckets in streaming mode. The main board consists of a direct sampling board operating with a minimum sampling time of 3 psec and a time jitter less than 1.7 psec. The very low noise layout design combined with a wide dynamic range and bandwidth of the analog front-end allows to sample pulse signals generated by various GHz/THz detectors, like NbN and YBCO superconductor film detectors or zero biased Schottky Diode detectors. The digitized data is transmitted to the DAQ system by an FPGA readout board with a data transfer rate of 4 GByte/s. The setup is accomplished by a real-time data processing unit based on high-end graphics processors (GPUs) for on-line analysis of the frequency behaviour of the coherent synchrotron emissions. The system has been successfully used to study the beam properties of the ANKA synchrotron radiation source located at the Karlsruhe Institute of Technology and operating in the energy range between 0.5-2.5 GeV | ||
