R. Kuramoto and A. Laxdal measured the distance from the 2A tunnel to the tank flange of ITE. The new fabricated beam pipe with bellows was used to gauge the distance to the tank flange; The flange face of the beam tube was butted up to the tank flange and the beam tube was marked at the plane of the wall. A metal rod was used to gauge the distance to the tank face using the same method.

From the inside of the tunnel wall:

- To tank flange: 45 5/16"

- To ITE vacuum tank face: 49"
