Subject: 17O3+ beam at optimized RF 

A comment about RF power came up at the presentation this morning. Intense X-rays can be produced not only at the peak efficiency and output of the RF amplifier but also as a function of other parameters including source gas pressure, isotope(s), whatever you can think of. I set the RF at a mid-level power, with power setpoint at 0dB and adjusted the RF for optimal current on FC6. This occurred at 13.0306GHz with 35W power. About 6nA of beam. Take a quick emittance scan.
