Turkish Accelerator and Radiation Laboratory at Ankara Suat ÖZKORUCUKLU İstanbul University THE GOALS The TARLA aims to obtain FEL between 3-250 µm using 15- 40 MeV electron beam. There will be two different optical resonators with undulators with 2.5cm and 9.0cm periods. In order to have wide research area, the electron beam is requested to be continuous wave with high current as well as pulsed with low current. We plan to use high average current normal conducting injector which operates CW mode and superconducting accelerators which are fed by solid state power amplifiers. We propose to use electron beam itself for material and detector research in the future 2 3RD TAC LIGHT SOURCES USERS’ MEETING (TAC-LSUM 2013) | OCTOBER 5-7 | 2013 | ANKARA UNIVERSITY Suat Özkorucuklu |Istanbul University THE PLANS We are planning on IR FEL Stations (5): • • • • • Photon science and diagnostics Ultrafast photonics applications General IR spectroscopy Material characterization Bio-micro spectroscopy and biomedicine and also Bremsstrahlung line after the second accelerating module for nuclear structure and gamma radiation studies TARLA is an official member of EU-FP7 Project named as CALIPSO for training of users in any 20 European Light Source Facilities 3 3RD TAC LIGHT SOURCES USERS’ MEETING (TAC-LSUM 2013) | OCTOBER 5-7 | 2013 | ANKARA UNIVERSITY Suat Özkorucuklu |Istanbul University TARLATARLA layoutLAYOUT 4 3RD TAC LIGHT SOURCES USERS’ MEETING (TAC-LSUM 2013) | OCTOBER 5-7 | 2013 | ANKARA UNIVERSITY Suat Özkorucuklu |Istanbul University ELECTRON BEAM PARAMETERS Parameters Value Energy [MeV] 16-40 Max.
