  Commissioning of the front-end of the linac at CSNS has been accomplished. Double scanning slit system and wire-scanners were employed to carry out the transverse emittance measurements in both low energy beam transport (LEBT) and medium energy beam transport (MEBT). Different results of different measurement methods are presented and compared. Corresponding codes were developed for each of the emittance measurement methods.

  Beam-based alignment (BBA) techniques are important tools for beam orbit steering in linear accelerators or transfer lines. In this paper this technique and the control system application programs developed based on XAL platform were applied to the beam commissioning for Medium Energy Beam Transport (MEBT) of CSNS to get the transverse misalignments of beam position monitor (BPM) and quad. The results shows that the absolute values of BPMs offsets are less than 0.6 mm and quads offsets are less than 0.05 mm,that is much smaller than the tolerance of the misalignment.
