McPherson - Model 642 -Soft X-ray Solid Anode Electron Impact Source
The Model 642 soft x-ray source is a compact, convenient to operate source for the 2keV to 50eV region. The unique dual-output of equivalent beams make it a useful source for many comparative applications in addition to wavelength calibration and so on. The two output beams originate from two views of the single emitting spot where the electron beam from the single hairpin filament collides with the interchangeable anode. The emitting spot is about 1mm diameter and depends on the source’s operating conditions.
The Model 642 is available as a single anode source. The anodes may easily be exchanged at atmosphere. The larger Model 642-1 is even more flexible. It has a multiple-anode carousel allowing the user to exchange anode materials without breaking vacuum. Both sources are good candidates for soft x-ray measurement and calibration applications. The soft x-ray sources are provided with a filament current controller and 10kV high voltage supply for operation up to 30 Watts. Option exists to water cool the anodes and operate with power high as 300 Watts. Please inquire.
