  The MAJORANA Collaboration will seek neutrinoless double beta decay (0nbb) in
76Ge using isotopically enriched p-type point contact (PPC) high purity
Germanium (HPGe) detectors. A tonne-scale array of HPGe detectors would require
background levels below 1 count/ROI-tonne-year in the 4 keV region of interest
(ROI) around the 2039 keV Q-value of the decay. In order to demonstrate the
feasibility of such an experiment, the MAJORANA DEMONSTRATOR, a 40 kg HPGe
detector array, is being constructed with a background goal of <3
counts/ROI-tonne-year, which is expected to scale down to <1
count/ROI-tonne-year for a tonne-scale experiment. The signal readout
electronics, which must be placed in close proximity to the detectors, present
a challenge toward reaching this background goal. This talk will discuss the
materials and design used to construct signal readout electronics with low
enough backgrounds for the MAJORANA DEMONSTRATOR.
