Check if you are intended to invest the beamline construction

HEPS is a national scientific facility for public research, open to users around the world. For the beamlines constructed and invested by the users, at least 30% beam time must be allocated to the public beamtime. Besides the beamline construction investment, the operation cost is also supported by the investor ( less than 10% of the beamline cost)

2. Upload the design of the new beamlline
