Chinese hamster ovary (CHO) cells and thermoluminescent detectors (TLD-700) were used for physical and biological verification of heavy ion treatment planning. Experiments were performed in a ...cylindrical water phantom, in some cases with lung and bone equivalent material in front of the target volume. The results confirm the possibility of using thermoluminescent detectors for a quantitative verification of dose distributions. CHO cells can be used at least for qualitative dose verification.
Measurements of the Xi- and anti-Xi+ masses, mass differences, lifetimes and lifetime differences are presented. The anti-Xi+ sample used is much larger than those used previously for such ...measurements. In addition, the Xi production rates in Z -> b anti-b and Z -> q anti-q events are compared and the position xi* of the maximum of the xi distribution in Z -> q anti-q events is measured.
