[en] The pumping system is a combination of four turbomolecular pumps with three stages pumping for the HL-2A vacuum vessel preassembling, giving a total effective pumping speed of 6.4 m3·s-1 (H2) for the vessel. The leak detection of base element and the vacuum vessel is performed with helium mass spectrometer leak detector and two mass spectrometry. The total leak rate of the vessel is below 1.2 x 10-5 Pa·m3·s-1. The base pressure is 1.1 x 10-4 Pa with suitable prepumping and outgassing
