Description
Both LCLS II 2K cold boxes feature a large vacuum vessel topped by a 2” thick flat plate, buttressed by a central column, that supports six cold compressors and connected piping. Multiple external bayonet arrangements permit modification of the flow path through the box so the nominal flow can be adjusted approximately 24% without altering the internal piping. All piping and the vacuum vessel are designed to meet applicable ASME and ASCE codes for operating, transportation and seismic conditions. AutoPIPE CONNECT was used to perform the piping flexibility analysis and ANSYS 17.2 was used to analyze the vacuum vessel.
