In order to utilize added advantages of CW beam obtained at TARLA, a bremsstrahlung radiation line has been planned. The Bremsstrahlung photon is going to be produced by the electron beam hitting a niobium foil in the accelerator hall. The photon beam will be collimated by a long collimator of high-purity aluminum installed in the concrete wall between accelerator hall and experimental cave. The exit of the collimator will be in atmospheric pressure due to the detectors installed around the target. The schematic view of Gamma beamline is given in figure.
