This weekly win post is for the win awarded on 10/10/16. The win that week was awarded to Roy Ready’s team, working on the Ra EDM project. The RaEDM team successfully tested the high voltage system, and reached a stable operating voltage of 22 kV. One of the goals of the project is to reach the highest possible stable electric field with the electrodes to be used in the upcoming Radium EDM experiment. The sensitivity of the measurement is inversely proportional to electric field, so if the field is doubled, so is the precision. In the 2015 experiment at Argonne National Laboratory, the experiment was operated with an electric field of 67 kV/cm. The electrodes that are currently being used are about 2 cm apart, so this gives an electric field of 110 kV/cm when operating at 22 kV. That is more than 1.5 times higher than the 2015 run!
