	Over the last few years the Shanghai Electron Beam Ion Trap (EBIT) has been successfully redesigned and rebuilt. The original machine, developed under collaboration with the Shanghai Institute of Nuclear and Applied Physics, first generated an electron beam in 2005. Shanghai EBIT could be operated with electron beam energies between 1 and 130 keV and currents up to 160 mAmps. After several years of operation, it was found that some improvements/modifications to the old design were necessary. This contribution will discuss several of the main aspects of the redesigned Shanghai EBIT. So far it has been operated up to an electron energy of 40 keV with an current density of over 2400 A per square cm. The new EBIT is made primarily from Titanium instead of Stainless Steel and has an order of magnitude better background vacuum, a more efficient and economical cryogenic system, and also excellent optical alignment. Finally the magnetic field in the central drift tube region can reach up till 4.8 T.

Over the last few years the Shanghai Electron Beam Ion Trap (EBIT) has been successfully redesigned and rebuilt. The original machine, developed under collaboration with the Shanghai Institute of Nuclear and Applied Physics, first generated an electron beam in 2005. Shanghai EBIT could be operated with electron beam energies between 1 and 130 keV and currents up to 160 mAmps. After several years of operation, it was found that some improvements/modifications to the old design were necessary. This contribution will discuss several of the main aspects of the redesigned Shanghai EBIT. So far it has been operated up to an electron energy of 40 keV with an current density of over 2400 A per square cm. The new EBIT is made primarily from Titanium instead of Stainless Steel and has an order of magnitude better background vacuum, a more efficient and economical cryogenic system, and also excellent optical alignment.
