Shahab | Runs | Life time of 10 MeV/u Tail of 118-Te-52+ | |
The life time of 10 MeV/u Tail of cycle 118-Te-52+ was analyzed using Schottky peak intensity. Schottky signal was taken from the parallel plate Schottky monitor at using the:
Tektronix RSA5103B analyzer parameters:
Frequency = 39.8380 MHz
span = 50 kHz
RBW = 100 Hz
AcqBW = 78.12 kHz
The peak intensity is integrated power of the resolution bandwidth.
Trigger was set to machine 12, same as gas target "on" signal. Each file contains 40 seconds of recorded signal. Spectra were calculated using sensitive multitaper method with additional averaging of every 10 time frames.
After evaluation of several Schottky spectra, except from some fluctuations, there was no significant change in beam lifetime with or without gas target. They are in the same order of magnitude, that is, it seems that target interaction is not so prominent compared to the rest of the ring. with a xenon target the situation would be much different.
Attached are some plots. Also here are the results of the analyzed files in text form:
Target off: average 9.21 sec
