The beam is set at the correct energy, operators cross-checked it again. What we see  at 750 is due to the molecular beam.  The operotors are trying to optimize and get rid of this in the next 30min.

Temps and system checks OK

Leakage current OK

Merger and tape server OK

Potentiometer at 28.06 mm and 29.23 mm

Keep going with the beam tests. A new peak appears around 950 keV( See attached). Still try to understand what it is. The operators keep going
