摘要：

We describe here a novel approach to luminosity measurements for p (p) over bar collider experiments. We propose to use low-pressure gaseous Cherenkov counters at small angles relative to the beam direction to determine the rate of inelastic p (p) over bar interactions. With a propotype counter, we measured at a beam test a light yield of over 100 photoelectrons and a timing resolution of better than 50 ps. The CDF collaboration will use a detector based on this technique for luminosity measurements at the upgraded Tevatron collider. (C) 2000 Elsevier Science B.V. All rights reserved.
