ANALYTICAL CHEMISTRY
New 5-inch, 10-stage head-on type phototube, called the RCA-8055, uses a 'Venetian blind" dynode structure. A company spokesman says that, besides being useful in scintillation counters, the tube's large photocathode area makes it especially suitable for uses requiring good photon collection from distant or diffuse radiation sources. The S-ll spectral response covers the range from about 3000 to 6500 ang stroms, with maximum response oc curring in the blue region a t about 4400 angstroms. Design includes a semitransparent photocathode having a minimum useful diameter of 4.38 inches, a first dynode with large area, a flat window to facilitate the mount ing of flat scintillators, and 10 dynode (secondary emitter) stages.
