Description	Notes

▶	1	Initial setup for short-pulse beam operation (30 bunches, 1nC/bunch, 1.2GeV)	
The idea here is to start with a known working reference file from FEL operation. It needs to be a high energy file because we're interested in running at high gradient
▼	2	Calibration of key parameters	
	•	2.1	Perform a vector sum calibration with the 30 bunches, 1nC/bunch	
This is needed before we go into the next set of tests, which are without beam
	•	2.2	Confirm power ratios and measured forward powers by comparing the measured gradients from the field probe signals	
This could be done ahead of time from existing DAQ data
	•	2.3	Piezo tuner setup for static cavity tuning	
	▼	2.4	Calibrate coupler position vs loaded Q (no beam)	
Repeatability is important here - getting the same loaded Q at the same coupler position, so we'll need to make sure, for example, that we always approach the desired position in the same direction to avoid backlash
At which gradient(s) do we do this??
	•	2.4.1	With RF on, tune all 16 ACC6/7 cavities to be on resonance in the middle of the 800us flat-top	
	•	2.4.2	With RF off, move coupler to it's minimum position (minimum Loaded-Q)	
	•	2.4.3	Enable RF and compute the loaded Q from the decay	
	•	2.4.4	In small increments (how small?), change the coupler position and measure the loaded Qs until the high value is reached	
	•	2.4.5	Move the coupler all the way back to the minimum value and repeat the scan of coupler position	
We're looking for repeatability in the measurements when we go in the same direction with the motor
	•	2.4.6	Pick a loaded Q value somewhere in the middle of the range	
	•	2.4.7	From the high side (high loaded Q), move the coupler to a position lower than required for the chosen Loaded-Q value, then move it back to the 	
	position that the previous measurements say would result in the desired loaded Q value	
	•	2.4.8	Repeat this test for a couple more values: ie always approaching the required coupler position from the same direction, verify the repeatability of the 	
	loaded Q measurements	
	▼	2.5	Coupler scans	
	•	2.5.1	Start with the loaded Qs at the nominal values from the beam setup	
	•	2.5.2	At low gradient, scan cavity tuning and monitor the decay (loaded Q)	
Brian did this at NML last week, and he confirmed that the loaded Q was not affected by the detuning
This is done either with DC drive on the piezos (hopefully) or using the mechanical tuners (very slow)
	•	2.5.3	Repeat some of the measurements taken on Nov 21st	
	•	2.5.4	Verify that we can adjust the loaded Qs over the ranges given by the simulations for currents between zero and ~6mA	
▼	3	Cavity model validation and low-gradient 'no-beam' Pseudo-Pk/Ql experiment	
Take some initial data to calibrate the model and our initial assumptions to validate / calibrate the 16-cavity model
First measurements will be without beam and at lower gradients in order to minimize the effects of LFD that would otherwise complicate the model validation
	▼	3.1	Set the cavity parameters assuming an 'ideal cavity', using a fill-time of 500us and a flat-top vector sum of ??MV	
	•	3.1.1	With learning FF off and feedback off, fine-tune the fill power / flat-top power to get exactly the desired vector sum at the end of the fill time and flat 	
	vector sum during the flat-top	
	•	3.1.2	Set forward power ratio for the initial feed-forward tables	
How is the forward power ratio determined?
	•	3.1.3	Turn on learning FF to do the fine-tuning of the waveform	
	•	3.1.4	Adjust the loaded Qs all to exactly 3e6 as measured by the field decay	
Note that this is not the default way that Valeri sets up the cavities. He makes small adjustments to the loaded Qs in order to get empirically flat gradients.
	•	3.1.5	Adjust the cavity static tuning so all the cavities are on resonance a the same exact time	
At what point in the waveform do we want the cavities to be on resonance?
	•	3.1.6	Re-adjust the klystron forward power ratios, loaded Qs and static tuning iteratively	
	•	3.1.7	Enter in the model the measured loaded Qs, measured Pks, measured detuning, and compare the gradients and gradient tilts from the model with the 	
	measurements	
If all cavities are identically tuned, have identical Loaded-Qs, and there is no influence from Lorentz-force detuning, then all cavity gradients should be exactly flat
•	4	Perform initial 'no-beam' Pk/Ql experiment at low gradient	
•	5	Check out scripts for performing experiments and associated 'live' data analysis	
Passive (hands-off) analysis scripts should already have been checked out before the studies
•	6	Dynamic Lorentz-force detuning compensation experiment	
▶	7	Set up the 'administrative' quench limits	
How and where is this done? Who can do it?
We don't actually want it to generate an MPS alarm, but we do want to know that it's happened.
▶	8	Perform 'no beam' Pseudo-Pk/Ql experiment at the nominal vector sum for 1.2GeV beam operation	
Presumably we base this on the nominal 1.2GeV optics file
▶	9	Establish long bunch train operation at 1mA (400 bunches, 1nC/bunch, 1.2GeV)	
•	10	Perform Pseudo-Pk/Ql experiment with 400us bunch-train and 1mA	
▶	11	Increase bunch charge to a nominal 2nC and 400 bunches	
•	12	Perform Pseudo-Pk/Ql experiment with 400us bunch-train and 2mA	
•	13	Set up drive laser and gun for 3MHz long-pulse operation (1200 bunches, 1nC/bunch)
