In this paper the fabrication technique of a single-ended coaxial Ge (Li) detector is described. The active volume of the detector is about 35cm3. The leakage current at 2500V bias is 4×10
-11
A. An energy resolution of 2.47 keV (FWHM) for
60
Co (1.332 MeV) has been obtained.
The technique of etch of surface without protection and the method of clean-up drift in the cryostat are discussed in detail.
