The researchers from our institute and CAS Xi'an Institute of Optics and Precision Mechanics garrisoned the base since the early July. They worked hard and successfully finish the devices' installing and debugging work. Now the devices worked very well and guarded the related water area unpausingly. Under the lead of Prof. Xu Feng, the colleges collaborated and cooperated strenuously and orderly. Their arduous work ensured the smooth progress of the event.
