ABSTRACT:
A method and apparatus for measuring the beam current of a particle beam in an accelerator by charging the capacitor across an operational amplifier and controlling the scaling of the amplifier output with a programmable gain amplifier (PGA). The out put of the (PGA) is sampled and storing with an analog-to-digital converter to acquire and store at least two digital voltage values. The two digital voltage values are using to obtain a value proportional to beam current. A field programmable gate array is used to implement digital logic to sample and hold output from the analog-to-digital converter.
