[en] A cryogenic target system for liquid ³He and ⁴He operating at temperatures between 1.2 and 2.2 K that can take one watt of electron beam power is discussed. For ⁴He in the superfluid state an effective target thickness nearly independent of beam dissipation was observed. In the case of ³He the effective target thickness changed only modestly and can be corrected for reliably. The resolution attainable in the ³He(e, e'p)²H coincidence reaction with this cryotarget and the electron and hadron spectrometers is shown to be 600 keV. (orig.)
