Description
The design of the DLS is based on pre-bunched FEL where a train of electron micro-bunches with a maximum energy of 8 MeV are being injected into a compact Undulator to produce the THz radiation in the range of 0.18 - 3.0 THz. The frequency tuning in this range is planned to be achieved by varying the separation of the laser micro-pulses which strike the photocathode to produce the electron micro-bunches. In order to produce ultra-short laser pulses, an advanced Fibre laser system having energy of a few J has been developed in collaboration with KEK, Japan. The Fibre laser system has been commissioned at IUAC for the production of micro-bunch electron beam from the copper photocathode. The photocathode deposition system developed in collaboration with BNL, USA was also commissioned in the past and recently it has started producing thin films. The RF conditioning of the photocathode gun has been accomplished and the electron energy of > 6 MeV has been produced in routine and the same beam is being injected in to the undulator to check the first lasing of THz radiation. The detail of the facility including its various sub-components and their operational details will be presented.
