The column structure shown in the photograph was tested during the week of 7 May, prior to installation of the acceleration tubes in the 25-MV Pelletron tandem accelerator. On 10 May, physicists from the National Electrostatics Corp produced a maximum potential of 32 MV, suggesting that the basic column structure will operate well at its design potential of 25 MV. Oak Ridge spokesmen believe this 32 MV is a record for a laboratory-produced potential difference.
