After a long waiting time, the Kr distillation column was finally delivered to LNGS. Kr-85 is one intrinsic radioactive source in Xe. The XENON100 experiment's sensitivity goal requires a Kr/Xe contamination level lower than 50 ppt. The current Kr/Xe contamination level in XENON100 is about 5 ppb. Cryogenic distillation through the new column, which will take about two weeks for the 170 kg Xe in the detector, will reduce the Kr/Xe level by three orders of magnitude, making the Kr-85 contribution to the XENON100 total background negligible. |
