Station 4 Muon Identifier Design• 2 X and 2 Y layers, coverage = 12’ x 12’
• Aluminum drift tubes for good position resolution track matching to Station 3 drift chambers
• Each plane constructed of 2 staggered rows of 2” diameter tubes for excellent efficiency and reasonable channel count
• Nanometrics amplifier / discriminator electronics with ECL output. • Well tested design with 1000’s of operational tubes.
• Works with a variety of gas mixtures @ ~ +2300V
