The new 14 GHz ECR ion source at ATLAS has delivered beams for several experiments during the past year and is now considered to be operational. The source is mounted on a 300 kV high voltage platform, similar to the 10.5 GHz source, and shares the duty with the 10.5 GHz source of providing beams to the PII injector. Initial operation from the high voltage platform has been compromised due to problems with power spikes originating from the solenoid power supplies. These spikes have limited the operational range of the injection coil, with a maximum operating current of 430 Amps. A new power supply with improved noise characteristics has been received and will be tested shortly. The 14 GHz source is of a single stage high-B field with limited radial access. The introduction of solid materials into the source via a small high temperature oven and the sputtering technique is discussed as well as the production and efficiencies of these processes. Beams developed to date and general performance results will also be discussed.
