Run 64 started.
150 keV/u beam on target, Target overlap confirmed with lifetime measurement using bunched beam.
We do not see Rutherford on the detector - perhaps this is a calibration issue - perhaps too much noise at threshold.
We leave for a few hours to see if we obsrerve any reactions peaks
Moved detectors in with servos only. Both arms are IN and stationary.
Left potentiometer = 36.54 mm
Right potentiometer = 37.96 mm
Horizontal beam position = -3.0 mm
data rate is ~5 MB/sec
Electron cooler read values; Cooler voltage = 88.57V, cooler current=1.28 mA.

Checks OK. I have increased the equal energy cut back to 500 keV and increased bin size on Ey energy histogram to 50 keV to try and see the nuclear peaks better.
Screen shot attached of monitoring code before it was reset. Some small peaks visible. |
