Recent Modifications to Hermes
The general layout of Hermes including the electron impact source unit has been described in detail elsewhere  and this paper will be confined to recent modifications. Preliminary runs with lead and uranium showed that the design requirements (high resolution at 1 mA and 4% efficiency) could be met, and since plutonium isotopes were urgently required, active runs were commenced without further delay. At that time no other high resolution heavy element separation results were available for comparison, and the Hermes performance was certainly better than that then obtained in calutrons.
