The signal charge loss due to initial recombination and that due to volume recombination have been measured separately using parallel plate ionization chambers irradiated with cobalt60 gamma rays, over a wide range of applied voltage and air humidity. It is shown that both initial and volume recombination depend on the electric field strength and also on(More)
