Description
Schottky Mass Spectrometry turned out to be an excellent tool for systematic nuclear mass measurements. The newly developed data acquisition system, which yields several advantages for the data analysis, was used for the first time in Nov. 1997. Instead of online Fourier transformation as in former measurements, the signal is now digitized with a sampling rate of 640 kHz (16-bit resolution) and stored as time-captures. With a continuous data rate of 1.2 MB/s nearly 1 TB of raw data were stored. The Fast Fourier Transformation offline analysis allows the study of the dynamical behavior of the stored ions in the ESR including cooling forces and decay. The new spectra contain enough reference nuclei to determine the deviations from the constant momentum compaction factor αp
