The AGS and the Tandem Van de Graaff, two valuable physics assets, are now joined together by a transport line 700 m in length. To minimize the beam loss due to charge exchange between the partially stripped heaviest ions and residual gas molecules, a vacuum of 10/sup -8/ Torr is required for this transport line. To achieve this vacuum, we have opted to use a combination of small ion pumps and distributed nonevaporable getter strips as pumps. Pressures on the 10/sup -10/ and low 10/sup -9/ Torr ranges have been maintained over the last two years following initial activation of the NEG strips. This paper describes the NEG strip system, and the experience obtained during the installation and operation of this 700 m heavy ion transport line. (AIP)
