We constructed two types of coincidence analyzers those can be used for Auger photoelectron coincidence spectroscopy and electron ion coincidence spectroscopy. The first one is designed for high electron energy resolution measurements, and consists of a double-pass coaxially symmetric mirror electron energy analyzer (DP-ASMA), a double-pass cylindrical mirror electron energy analyzer (DP-CMA), a time-of-flight ion mass spectrometer (TOF-MS), a magnetic shield, a conflat flange, an xyz stage, and a tilt adjustment mechanism. The second one is dedicated for high sensitivity measurements, and involves an ASMA with a large pinhole, DP-CMA with a large pinhole, and a TOF-MS.
