A Penning Multiply Charged Heavy Ion Source Test Facility

An ion source test facility has been constructed at Oak Ridge National Laboratory for making fundamental measurements of the properties of Penning ion sources. The extracted ion energies from the source can be up to 36 × q (keV), where q is the ion charge. Both negative and multiply charged positive ions have been extracted from the source. The facility has high current capabilities for acceleration and for the arc power supply. These low-energy, multiply charged ions are currently being used for measurements of charge exchange cross sections, x-ray production, and electron impact excitation and ionization.
