Two-proton correlations at small relative momentum q were studied in the eA({sup 3}He, {sup 4}He, C, Fe) {yields} e{prime}ppX reaction at E{sub 0} = 4.46 GeV using the CLAS detector at Jefferson Lab. The enhancement of the correlation function at small q was found to be in accordance with theoretical expectation. Emission region sizes were extracted and proved to be dependent on A and proton momentum. The size of the two-proton emission region on the lightest possible nucleus, He, was measured for the first time.
