Abstract: A new plasma chamber for the Texas A&M 14.5GHz ECR ion source ECR2 has been recently installed and the beam analysis line has been recently upgraded with the replacement of the solenoid with a shorter Glaser lens. The source is now used along with the 6.4GHz ECR1 for injection of beams into the K500 cyclotron. The new plasma chamber incorporates water-carrying copper tubes, each with an inner diameter of 0.7mm and an outer diameter of 1.8mm, interposed between the NbFeB permanent magnets and the aluminum plasma-chamber wall. The design allows for a much higher water flow and thus better cooling than the previous design, which used a thin, water-cooled liner. The source commissioning and operation is described.
