Texture Diffractometer, called DN2, is one of neutron diffractometers in BATAN which is dedicated for texture measurement using neutron diffraction method. To obtain better performance of the DN2, a flight tube goniometer have been installed between the monochromator and sample position. By adjusting the flight tube goniometer, defocusing effect at direct beam and background effect could be reduced significantly. Some experiments have been carried out to characterize DN2 performance. The flight tube goniometer alignment and neutron wavelength calibration were characterized using silicon standard sample Si640d. Data refinement of diffraction pattern was analyzed using MAUD software and it is obtained reliability factor with background, R wpb , reduced significantly, from 42.53 % to 19.36 % after setting of flight tube goniometer. Reliability factor without background (R wp ) was reduced from 27.41% to 21.36%. Calibrated of neutron wavelengh, λ = 1,2799 Angstrom is obtained.
