Title: Review of Capture Pumping Technology
Review: In 1991 Kimo Welsh wrote the definitive work on capture pumping. In this new edition he has added several sections that are of particular note. One is on leak checking systems that use helium cryopumps, which poses some unique problems, (Sec. 1.20) and another is on the use of Meissner coils in the vacuum chamber (Sec. 5.5.4) where there is high conductance for water vapor to reach the condensing surface. There is also a new section on vacuum seals (Sec. 1.19) that provides useful information. Kimo has a very readable and informative style of writing and his Chapter 1 on BASIC THEORY should be read by anyone interest in vacuum technology and engineering.
