Emittance Measurement: IHA0L07 X-plane - Not too far from design as found
Follow-up Re: 1L22 llrf testing
rebooted the ioc with more software and firmware updates.
ran the klystron characterization up to 8 kW. Couldn't go higher due to the 8 dB pad installed on the klystron drive on field control chassis.
added the beam permit functionality and need to do some more testing tomorrow
verified the cryo heater interface (GMES vs heat)
also need to measure the amplitude and phase regulation
whole zone will be upgraded to the new software and firmware tomorrow

rayTrace analysis for Y run with some loss
Plots go through the order of raw data, then show the singular values (SVs).
Then we clean with SVD using 2 SVs, 3 SVs, 4 SVs, etc...
There is a persistent issue with this specific dataset using the SVD data cleaning/cuts. At first, it was assumed to be related to the beam loss we experienced, but this persisted with decreased cuts.
To be investigated further. But the raw data is actually good enough to use.
