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

<p>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.</p>
<p>Screen shot attached of monitoring code before it was reset. Some small peaks visible.</p> |
