POLARIZED TARGET UPDATE D. G. Crabb UVA
Refrigerator UVA fridge and JLab Fridge clones Both leaked badly (from the same place) after ~20 years of operation New fridge (actually canabalized) put together at UVA. Tested and works like it used to. Similar work at Jlab.
NH 3 from NIST Irradiation (2009)
NH 3 (same material)
NH 3 (2 nd Batch)
NH3 Inventory According to our inventory Fresh 14 NH 3 on hand from Irradiations from 7/09 and 10/09 is about target loads. More exists from previous experiments but may not get to 90%.
NIST Irradiations MOU between NIST and UVA now needed for irradiations. Currently in the hands of NIST lawyers. Then NIST --> UVA lawyers NIST lawyers UVA lawyers and so on ! Only a few people can sign on behalf of the University and I’m not one of them! Technical Issues Maybe a change in procedure due to e A p + 39 Cl (12.6 MeV threshold)
