Title: Electrons on the HDice target: Results and analysis of test runs at JLab in 2012

During the Jefferson Labaratory E06-101 (g14) experiment \cite{g14} utilizing photons on solid HD and performed in Hall B, two opportunities arose for targets to be subjected to multi-GeV electron beams in week-long campaigns of dose accumulation and NMR polarization measurements. This was in preparation for conditionally approved electron experiments after the 12 GeV JLab upgrade\cite{trans}. Besides the important thermal effects, evidence consistent with screening of the NMR and with decay of the target polarization was observed during bombardment and for a time afterwards. The solid hydrogens have been the subject of previous radiation damage studies, both for possible polarized DT fusion\cite{Forrest97} and for production of dynamically polarized nuclear targets\cite{Radtke04}. We synthesize all this information into an overall picture that can guide on-going development of the HDice target system for future use.
