Description
The CEBAF accelerator has a demonstrated capacity for delivery of electron current to Hall B at the ~100 nA level, on par with the current anticipated for future positron beams. However, machine configuration requires macropulse current levels of a few micro-Amperes due to limited sensitivity of many installed diagnostics. Informed by this operational experience, we outline a set of diagnostic extensions leading to operationally reliable delivery at JLab of a low-current beam of positrons. Alternate diagnostic choices are listed, as well.
