Hall-A program<br />

Future possibilities<br />

◮ <strong>DVCS</strong> on <strong>the</strong> neutron <strong>at</strong> <strong>12</strong> <strong>GeV</strong><br />

◮ Extention to <strong>the</strong> full kinem<strong>at</strong>ic domain available with JLab <strong>at</strong> <strong>12</strong><strong>GeV</strong><br />

◮<br />

System<strong>at</strong>ic uncertainties improved<br />

◮ Recoil polarimetry (R+D)<br />

◮ A full <strong>DVCS</strong> program requires proton polariz<strong>at</strong>ion measurements<br />

◮<br />

◮<br />

Observables of proton recoil polariz<strong>at</strong>ion in ⃗ep → e⃗pγ<br />

are functionally equivalent to <strong>the</strong><br />

observables ⃗e⃗p → epγ <strong>for</strong> polarized targets<br />

Conceptual design of a large acceptance recoil polarimeter<br />

(longitudinal <strong>and</strong> transverse proton polariz<strong>at</strong>ion) under development<br />

◮ High luminosity (> 10 37 cm −2 s −1 ) 3 He target<br />
