Transcript LSUM Sunum Suat - Turkish Accelerator and Radiation

Turkish Accelerator and Radiation
Laboratory at Ankara

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

The design of the 1.3 GHz Buncher is similar to t he 260 MHz Buncher.
The 260 MHz cavity has 2 beam ports one on ea ch disc and 4 ports on the cylinder mantle.
The four ports are for the variable tuner and opposite to this for the frequency adjusting slug.
Two horizontal ports allo w the installation of the input coupler and the field probe.

ACCELERATING SECTION
Main accelerating section will consist of
• 2 superconducting SRF modules
Bunch compressor located between two modules
• 1 mA CW beam provided by injector will be accelerated up to 18 MeV in
first linac;
• The bunches at maximum 18 MeV will be compressed down to 0.5ps (or
decompressed) in bunch compressor section. (Due to capture process a
dogleg style bunch compressor has been designed.);
• In the second state of this section beam will able to be accelerated up to
40 MeV.

EXPECTED FEL PARAMETERS
• Plots shows gain (left) and intracavity power (right) behavior versus round trips
between mirrors..
• It is seen that gain for longer wavelengths (therefore saturated power) is too
small..
The calculations was performed for optimum out coupling factor etc. bunch length
and detuning has been optimized for different FEL wavelengths lengths

SUMMARY
 Commissioning of gun is continuing
 Currently we are making some modifications on our building for
 user labs, cyrogenics and radiation safety infrastructure.
 The injector will to be ready by the end of 2014. Commissioning
will take about 6 months (including all tests)
 The helium plant will be ready by the mid of 2014
 First cyromodule will be delivered by September 2014. We
expect to get first beam from SRF1 by the mid of 2015, and beam
from SRF2 is expected by the end of 2015
 Additionally we plan to start TARLA-2 project by next year in
order to purchase the undulators and resonators...

SUMMARY
TARLA is the first step of TAC project and will be
the first FEL user facility in Turkey and around our
region.
Its wavelength and power alternatives could allow
extensive FEL opportunities to users.
That’s why we need your input and comments as
potential users and experts
