For the high resolution gamma ray detector array EUROGAM new data acquisition solutions are being developed. Large volume high purity Ge detectors, with new shapes for increased efficiency, have been proposed and prototypes are now being tested. High resolution analog and digital electronics will be integrated within the VXIbus system to be used as the front end instrumentation bus. Also, distributed processing solutions are adopted in order to cope with the high data rates.

A high-resolution, germanium p-i-n diode gamma-ray spectrometer has been made using the coaxial method of lithium drift. The detector described is ~ 16 cm3 in sensitive volume, three to four times that of the largest "planar" drifted diodes of this type described to date. Its performance as a spectrometer is comparable with that of smaller diodes; resolutions (fwhm) of 3.3 and 4.8 keV were obtained at γ-ray energies of 122 and 1 333 keV respectively with a detector bias of 1 000 to 1 500 V. Typical γ-ray spectra obtained with sources of 57Co, 60Co, 137Cs, and Th(B + C + C″) are shown. Also shown are curves of intrinsic full-energy peak efficiency over a range of energies. This efficiency is 2.5% at 1 300-keV γ-ray energy—comparable to that of a NaI scintillation spectrometer 1 in. in diameter by 1 in. long.

The gamma-ray spectrum of 159Tb following the β decay of 18.6 h 159Gd has been studied with high resolution Ge(Li) detectors. Eighteen transitions were observed, two of which are reported here for the first time. The previously reported complex nature of the 617 keV transition has been examined and high resolution studies have revealed a doublet structure with energies 616.5 ± 0.3 and 617.7 ± 0.2 keV and intensities of (2.3 ± 0.6) × 10−3% and (15.0 ± 2.3) × 10−3% per disintegration respectively. Gamma–gamma coincidence experiments were performed with large volume coaxial and thin window planar Ge(Li) detectors, using the related address technique and on-line computers. These experiments have established levels at 58, 138, 348, 363, 581, 618, 674, and 855 keV. All of the transitions observed in the direct spectrum have been fitted into the level scheme.
