ED - Schaa, Volker RW TI - SNS RFQ Voltage Measurements Using X-Ray Spectrometer J2 - Proc. of IBIC2016, Barcelona, Spain, Sept. 13-18, 2016 C1 - Barcelona, Spain T2 - International Beam Instrumentation Conference T3 - 5 LA - english AB - Absolute measurement of vane voltage is essential to understand RFQ transmission. We used a non-intrusive technique of bremsstrahlung X-ray measurement. Several windows were installed at SNS to allow measurement of the X-ray spectrum in different locations of the RFQ. A CdTe spectrometer was used to estimate spectrum cutoff energy that corresponds to the vane voltage. Different device setups are described as well as measurement accuracy and interpretation of experimental data.
