Measurement of gamma-T with the gamma-T Quads On and Off
  An experimental procedure for measuring gamma-T has been developed and tested in two different measurements, with the gamma-T quads on and off. The results were compared to MAD calculations. The discrepancy between the measured gamma-T and the calculated gamma-T is less than 5%.
