180307:hf test


What we did
hf output power
generator power vs hf power
measuring the rf pulse rise time
plasma line movies.



What we did:

HF output power

Plots showing hf tx drive and output power (.ps) (.pdf)

Generator power vs hf output.

    The data from the 2 running generators was used to measure how much generator power was needed to drive the 5 hf transmitters.

GenPwr notes:

Measuring the rf pulse rise time:

    On 26jun17 we measured the rise time of pulses through the transmitter by looking at the rise time of the rf coupler output
on an oscilloscope. We found that:

    On 07mar18 we measured the rise time of an rf pulse at the hftx5 monitor ports. The setup was:
