Stable & Repeatable Ramping of 40 kV/mm Electric Field
The weekly win for this week is the conditioning team’s efforts in the ramp simulations. In 2.5 days we put the Nb23 through approximately 16 hours of ramping simulations. On Friday we continuously ramp-conditioned the electrodes for 8.5 hours at 40 kV/mm = 400 kV/cm, which is our current record for…

Farewell Andy & Courtney! (2017 MSU REU Poster Session)
Andy and Courtney have completed their REUs with the group this summer and presented their results at the REU poster session. Andy developed a machine vision system for characterizing the HV electrodes used for the Ra EDM experiment. This optical method is high resolution (10 microns), high precision (repeatable),…

Stable & Repeatable Ramping of 170 kV/cm Electric Field
This week we hit a milestone by successfully running a ramping simulation to 170 kV/cm for ~ 1 hr. This is approximately 15% higher than the goal we set out to reach and more than double the electric field that we were able to achieve during the Ra EDM data…

High Pressure Rinse of High Voltage Electrodes
This weekly win is about removing sub micron-sized particulates in the air we breathe from the Ra EDM electrodes, whose electrical performance can be degraded by the presence of these particulates, with a process called the high pressure rinse. The high pressure rinse is a critical step in decontaminating electrodes that we’ve adopted from accelerator science,…

Conditioning of HV Electrodes
This week we successfully approached the point of electrode conditioning with our high voltage system. In previous attempts, we were forced to stop short of reaching a high enough voltage due to cable failure–22 kV was the highest we could get. On Tuesday, we were able to reach 27.9 kV…

E-Field of 110 kV/cm
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…
