Resolution of a position-sensitive proportional-counter with a resistive anode wire of carbon fiber

Theoretical and experimental analyses have been performed to examine the po sition resolution of a proportional counter with a 7-mu m diameter carbon f iber as a resistive anode, which is used to encode one-dimensional position s of incident photons according to the charge-division method. These analys es have clearly shown that the carbon fiber is applicable to the position s ensing of the order of 100-200 mu m as long as the filled gas is pressurize d at near 10 atm.
