Description
Four DQW series cavities used for vertical crabbing in HL-LHC have been manufactured and tested at the CERN vertical test facility. Each cavity undergoes a sequence of cold tests starting from the bare cavity up to the cavity in its final configuration with all HOM couplers and field antenna. Experience with the first batch of DQW series cavities on RF measurements during manufacturing and cold testing with a focus on RF measurements with HOM couplers is presented. Issues related with early quench on two of cavities with HOM couplers including field emission onset are discussed.
