A typical parts list is included. This circuit particularly the input, is subject to change as experience is gained. Tests indicate that the circuit parameters of a Higinbotham circuit are wide. This conclusion is based on tests of two scalers made by Wendell Bradley's group and tested largely through the efforts of Stanley Cooper. Further work is envisaged and will be reported on in due course. John Simpson reports that a Higinbotham has been driven at 800 K.C. He achieved this with a special input circuit and a regular pulse. In the early stages he was also careful about stray capacitances. An oscilloscope was used as a recorder. 收起
