| TUPJE004 | Narrow Band Coherent Edge Radiation at UVSOR-III | 1613 |
|
||
| Edge radiation can be an interesting new light source because of its property that the radiation is well collimated and is radially polarized. We are developing coherent light sources in the THz region at UVSOR-III storage ring. We have already succeeded in producing a narrow band coherent THz radiation by manipulating the interaction of a relativistic electron bunch with an amplitude modulated laser with. Recently a simplified tentative beamline for detection of the edge radiation is installed at downstream of a short straight section of UVSOR-III. Coherent radiation from electron bunches after the interaction with the amplitude modulated laser is observed. Detailed measurements of polarizations and special distribution of the radiation are underway. The latest status of the study will be reported. | ||

| MOPHA009 | Single-Shot Electro-Optic Sampling Combined With Photonic Time-Stretch: Detailed Results at SOLEIL | 795 |

Funding: ANR (DYNACO project), FEDER, CEMPI LABEX. Single-shot recording of pulses is possible with high repetition rates (more than 80 MHz), as was demonstrated in the framework of a PhLAM-SOLEIL collaboration * **. This can be achieved by a relatively simple upgrade of existing setups based on spectral encoding. The strategy consists to encode the sub-picosecond information into the time domain, but at a slower scale (nanoseconds), using dispersion in a long optical fiber. Then the information is recorded by a photodiode connected to an oscilloscope. In this poster, we present guidelines for the practical realization of the electro-optical setup, as well as a performance analysis. In particular, we analyze the temporal resolution and compare it to the classical electro-optical sampling setup. * E. Roussel et al., Proceedings of IPAC2014, THOBA01. ** E.

| TUPWA011 | Progress on the LUNEX5 project | 1416 |
|
||
| LUNEX5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation) aims at investigating the production of short, intense, coherent Free Electron Laser (FEL) pulses in the 40-4 nm spectral range. It comprises a 400 MeV superconducting Linear Accelerator for high repetition rate operation (10 kHz), multi-FEL lines and adapted for studies of advanced FEL schemes, a 0.4 - 1 GeV Laser Wake Field Accelerator (LWFA) for its qualification by a FEL application, a single undulator line enabling advanced seeding and pilot user applications. Different studies such as on two color FEL and R&D programs have been launched. A test experiment for the demonstration of 180 MeV LWFA based FEL amplification at 200 nm is under preparation in collaboration with the Laboratoire d’Optique Appliquée, thanks to a proper electron beam manipulation. Specific hardware is also under development such as a cryo-ready 3 m long undulator of 15 mm period. | ||
