Here is Matt after a good day of IBIL and PIXE on various mineral grains (zircons, etc.) The ion source is cooling and he is cleaning his sample holders.
Eric made this great plot to help us understand the properties of the fragments from the decay of 13Li, 12Li, and 9He. Each of these unstable nuclei emit neutrons when they break up after surviving about 10-20 seconds
Tim’s week ended with manual labor after the low background counting station was found to be grossly contaminated. Here he is washing one of the lead shielding blocks.
