The Great High Voltage Test Station Upgrade of 2017
The weekly win is installation of the long-awaited soup cans. The significance of them might be lost on those who have not had to install HV cables with the clamshells. The short of it was that installing the cables with the plastic clamshells was torturous. The soup cans have NONE…

The Great Bipolar High Voltage Power Supply Installation of 2017
What is a bipolar power supply and why do we need it? In the Ra EDM experiment, a high electric field flips sign on a roughly 1-minute cycle. The direction of the field is changed by reversing the sign, or polarity, of the voltage being applied across the “hot” cathode (field is…

The Chunk Code: HV Stability During an EDM Simulation
This Weekly Win is a celebration of my high voltage ramp test analysis suite, AKA Chunk Code. Let me break this down into ‘chunks,’ if you will: Here is a plot of a high voltage ramp test the Spinlab RaEDM crew performed on 7-5-2017. The ramp test simulates the conditions that the electrodes will be subjected to…

HVPlotter in Python
Over the last week, I have developed a program in Python for quickly plotting data made from the exported data from the jhv4 labview program. The program has the user select which file they want to make plots from, and then opens the attached window. The user will then select…

Safety Interlock for HV Supply
This week is all about our electrode test station. We’ve made significant safety improvements and improvements in the sensitivity of our high voltage measurements. The first is the installation of our fancy new Interlock Chassis, which allows us to remotely shut down the power supply. It also automatically cuts power to the high voltage power supply…

Assembly of HV Electrode UHV Chamber
One of responsibilities for the Ra EDM experiment is to test and condition high voltage electrodes. The goal is to achieve an electric field that is at least three times higher than what we’ve achieved in the past. This should improve the statistical sensitivity of our experiment by at least…
