Proton abort gap losses suddenly dropped at about 18:25. (Not that we're complaining!) Giovanni called the MCR and they had no idea what could cause it.

<!-- Comment: Tue Mar 30 19;05;50 comment by...Paul -->
Rob Harr theorized that the decrease in the abort gaps might be caused by D0 moving their pots. As you can see from the above graph, there was indeed substantial pot movement at around that time -- but it seems like the timing is just a little bit too late, since the decrease happens before the pot reaches its final position. Maybe it's the movement of the pot that's causing this effect? Or maybe it wasn't caused by this at all, but something else entirely. I don't know.


<!-- Comment: Tue Mar 30 19;26;11 comment by...Paul -->
Whoops! These plots are for the rates in the pots, not the position (you would think the fact that they're in Hz would have tipped me off). See corrected graph below.

Real D0 pot position during the time when we saw the decrease in the proton abort gap. As you can see, now the timing works out -- the decrease seems to happen as the pot moves to its farthest in position.
<p>
I don't know why this would affect only the proton abort gap and nothing else.



<!-- Comment: Tue Mar 30 19;42;39 comment by...rainer -->
there is one theory whereby the electron lens excites resonances in the orbits of the abort gap particles which then could further be scraped by the pots like a collimator. but there are others much more knowledgable who should comment (with initials r.m. maybe ? ;)

Hourly plots 1900-2000. Slight uptick in proton abort gap losses but it's still lower than it was before D0 moved their pots, so it's not all bad. No obvious causes for this, though.

Some kind of RF problem caused the proton abort gap losses to go way up (about 35 kHz). We halted the run and took the silicon to standby. MCR called and said it was some kind of trip. We'll wait to see what happens to the losses before going on.

Pinkie on AVDD for SVX B5/W2/L4. Unmarked it but it stayed yellow since we're currently halted. We'll see what happens when we start up again.

Turned pink again (we're not even running again yet!) Will page silicon.

Abort gap losses during the RF incident. Note the greatly changed scale. As of right now, B0PAGC is down to about 5 kHz and everything is green on TevMon.

Hourly plots 2300-0000. Note the problems in RFSUM and RFSUMA causing the abort gap problems. See plot in preceding entry for better abort gap plot.


<!-- Comment: Wed Mar 31 00;20;11 comment by...rainer -->
this is a classical behavior of an RF station trip. according to MCR elog, TRF8 tripped off.
<!-- Comment: Wed Mar 31 07;50;46 comment by...R.J. Tesarek -->
These plots are a bit disturbing.  The RF station appears to have
taken somewhat longer than usual to "drop out".  RF station 8 
also tends to fail more frequently than others.

Proton abort gap now down to about 4.5 kHz. Everything is green in TevMon, so silicon has given us the OK to go ahead and power the silicon back up.

I should also mention that it seems to be stabilizing at around this level. (Before, they were pretty steady at ~3 kHz.) Antiproton abort gap losses showed a slight bump but are now pretty much back to where they were before.

Few minutes before the end, a RF trip in the Tevatron caused  
high losses, and the Si was brought to stdby. Situation recovered in few minutes, run was not ended.</pre>
