Abstract
RF-driven (internal and external antenna), Cs-enhanced H− ion sources at the Spallation Neutron Source (SNS) facility are capable of producing high current (>60 mA), high duty-factor (1 ms, 60 Hz) H− beams lasting multiple months. A solid reaction Cs dispenser system is used to cesiate the ion source. This work reports on our continuous effort to optimize the ion source cesiation process guided by the Cs signal observed with the plasma emission spectroscopy to mitigate the Cs induced high voltage sparking while assuring to enable high H− beam currents
