  At the SNS a beam current measurement technique called CHuMPS (Chopper Machine Protection System) has been developed that is fast, has a large dynamic range, and is droop-free. Combined with the LEBT chopper controller, a beam in gap measurement is possible that can accurately measure the beam in the chopper gaps. The beam in gap measurement can then provide machine protection in the case of chopper failure. The same application can also measure waste beam from the ring injection stripper foil and provide fast protection from stripper foil failure.
