<div class="">Dear Colleagues,</div>

<div class="">Many things went well last week; we got the machine up & running, the first exposure on the foil stack (Ni, Va, & Ga71) went perfectly, the test irradiation of the solid graphite block went well, and the machine ran great with no trips for more
than a shift. A number of trim magnets went off loop in the early hours of Friday morning. After some work on the trims beam was turned back on CW, there was another BLM trip more trim work & back to CW, this time it resulted in a vacuum leak & the run was
halted.</div>
