It uses a digitizing oscilloscope and provides the user the ability to configure scope settings for optimal data acquisition from a resistive wall monitor. When the program is launched, it secures complete control of the scope. Subsequently, a special “one-shot” timeline is generated to initiate the beam injection into the Booster. After the completion of the beam injection from the LINAC, a gap of about 40 ns is produced in the Booster beam using a set of kickers and line-charge distribution data is collected for next 200 μs. The program then analyzes the data to extract the gap width, beam revolution period and beam energy spread. We illustrate a case with an example. We also present results on beam energy spread as a function of beam intensity from a recent measurement.
