Commissioned interlocks, added reflected power signals on channels 4 and 5.

Changed output attenuation from 20 dB to 16 dB.

Readjusted the loops, check interlocks, tried highest fields. Consistently
trip around 2.9 MV.

Measured klystron saturation curve in open loop:

klysat.dat - Normal direct loop gain, maxes out around 2.88 MV
klysat1.dat - Increased direct loop gain from 0.6117 to 1, reached flat top.

Clearly between 2.8 MV and 3 MV the klystron reaches full saturation.

However, we see mystery trips on reflected power (trip level 10 kW, steady
state 0.7 kW) at the highest field levels. No real explanation so far.

dataset1.dat - Stripchart data with amplitudes/phases, includes injection to
               50 mA
dataset2.dat - Same time span as above, tuner stripchart

Ramped up to 1.6 GeV by first increasing the RF voltage from 1 MV to 1.5 MV,
then ramping. At the top, adjusted the RF voltage to 1.321 MV for the
synchrotron frequency of 87.55 kHz.

dataset4.dat - tuners on the same one

Next we fill and try to ramp to 2.35 GeV. RF voltage set to 1.98 MV
(setpoint of 0.4798). Ramped successfully, synchrotron tune 87.4 kHz.

dataset5.dat - Operation at 2.35 GeV, beam loss.

Now we operate in the booster mode with setpoint at 0.7 (2.884 MV), forward
power is 187 at the highest current/energy. Synchrotron tune of 87.2 kHz

To make the booster mode work we had to rotate the station phase by 80
degrees.

Tripped the RF on false arc signal
