Using two Fast Current Transformers (FCT), particles' Time of Flight (ToF) can be accurately determined by using windowed cross-correlation method. Existing techniques use pulse width or edge delay measurement to get the ToF. The accuracy of these methods, however, is limited by sampling rate, signal level, noise, and distortion. By using Cross-Correlation and interpolation, on the other hand, a fractional delay measurement can be obtained, and the system works with low level signals, i.e. high S/N ratio. During experiments, time delay measured between the two signals was 9.4023 ns. By using relativistic equations cyclotron energy was calculated and found to be 25.99 MeV, bearing in mind that cyclotron energy (mentioned in the CS30 manual) is 26.5 MeV for protons. The difference between actual and calculated energy was <2%. Results will be further discussed and analyzed.
