<span style="font-size: 12pt; color: black;">In the last year, several workshops aimed at pursuing an energy upgrade to 22 GeV of CEBAF with the goal of advancing the frontiers of our knowledge across the spectrum of topics in nuclear physics have been organized
by the JLab user community and staff with guidance from JLab management. This upgraded facility at the luminosity frontier will open up a rich and unique experimental nuclear physics program that combines the illustrious history of the laboratory with an exciting scientific
future. </span><span style="font-size: 12pt; color: rgb(255, 38, 0);"> </span><span style="font-size: 12pt; color: black;">Following the workshops, an editorial committee<span class="x_x_apple-converted-space"> </span>has collected input from the community
and assembled a<span class="x_x_apple-converted-space"> </span>White Paper that outlines the scientific program with CEBAF at 22 GeV. </span><span style="color: black;"></span></p>

this initial list have made important contributions to this program. While this grass-roots effort started with conversations among the workshop participants, many others have expressed interest in this program, contributed through discussions outside of
the workshops, or plan to contribute in the future. </span></p>
