| Abstract: | A special design of collimation system has been emploied on the DCMT. The automatic collimation system is an important part of the DCMT. The collimation system and the principle for determing collimation error are introduced. The repeatability of collimator is about 0". 03 according to the measurements in real operation of the DCMT. |
