The design, construction, and evaluation are described of several experimental camera tubes employing the SEC target, stressing the compatibility of SEC targets with photocathodes of the S-20 type. Special problems connected with scanning the SEC target by a low-velocity direct beam are discussed as well, as a solution to the problem of target crossover under over load, the use of an additional screen in front of the reading side of the target. From the experimental data presented, it is concluded that camera tubes of the type described compare favorably in over-all performance with conventional camera tubes using return beam readout, while presenting several practical advantages due to the use of the SEC target.
