【 摘 要 】

After commissioning the AstroBox2 detector has been used already for several physics experiments. During some of the experiments systematic effects in the measured decay spectra have been observed and related to gain shifts due to the environment, the chemical nature of the isotope under investigation, and to the beam implantation rate. In this article we report the observations and influence of these systematic effects that may well be of interest to other similar experiments with stopped rare isotope beams and detectors relying on gas amplification. Full characterization and understanding of these effects call for further systematic studies.
