Abstract
An Electron Cyclotron Resonance (ECR) heavy-ion source is under construction at the LBL 88-Inch Cyclotron. This source will produce very high charge state heavy ions, such as o8+ and Ar12+, which will increase cyclotron energies by a factor of 2-4, up to A = 80. It is a two-stage source using room temperature coils, a permanent magnet sextuipole, and a 6-9 GHz microwave system. Desiqn features include adjustable first to second staqe plasma coupling, a variable second stage mirror ratio, high conductance radial pumpino of the second stage, and a beam diagnostic system. A remotely movable extraction electrode will optimize extraction efficiency. The project includes construction of a transport line and improvernents to the cyclotron axial injection system. The construction period is expected to be two years.Keywords
