I ran through a calibration exercise for the IOS slits. Here is my data. I have moved each set to the midpoint of the largest (5mm) slit position. This does not necessarily agree with the book value. Never mind. Leave 'em alone, even though it appears that the numbers are switched (they're not).

Check 18O4+ emittance and compare with yesterday: good. Note again that emittance rig is running with manually-fitted reverse bias. |
