Abstract

The construction and performance of two uniformly graded electric field drift chambers are described. A test chamber, 260×260 mm2, and the prototype chamber, 2.9×3.5 m2 both have a drift space length of 60 mm and a gap width of 15 mm. The self-supporting cathode planes are constructed from lightweight honeycomb panels and consist of 3 mm copper strips on a 6 mm pitch.

The chambers were identical in performance and operated with full efficiency, constant drift velocity and a spatial solution of better than 0.35 mm throughout their active areas.
