In attendance: J. Nelson (notetaker), R Chestnut, R Hall, J Rock
SLED FDBK through SCP slow feedback
Folks keep turning it off. Not clear if it’s the labview or the fdbk. BM works just fine though … Janice will make time to troubleshoot, perhaps not until after ITRP visit.
SIS waveforms archived every hour (plus on change)
(still true) Done by HamHandsLite™ for now. We do want this and around early April.
Database and Displays
Judy thinks the klystron summary is ready. Tr07 coming soon. She will call when ready to reboot tr07.
(still true) Working great. Everyone is happy happy happy.
macnair module support of aes
(still true)(Debbie’s working on it, Yeah!) There is still a bit more database stuff to install. RMS/BIG requirements for 8-packs structures: Ron gets to choose which is easier – one loop for all MacNairs in tr09 and tr06, or one loop for each ioc
(Ron will look or send to Janice) Will need to be able to archive the gain and set the gain (internal to module). (potentially different for each module)
Will need to have AES on structures in tunnel April 1stish
2-pack PLC coming in April-ish.
(still true) ~20 signals as yet undefined. Janice will ask for TP printouts for this PLC too…
NLCTA/8-pack summary display
Ron sent instructions to Tonee about how to change the windows machine’s settings. Might not get done until after ITRP visit. In meantime, can reboot tr08 to reconnect after reboot of PC.
Requests to not lose
-support for Power regulation feedback. (later)
We plan that if we need to reboot tr08 this week, we will turn off RF/modulator manually before reboot to keep from getting high power spikes.
(from last time)
Ron says every time the proc loop processes (ADC triggers) it sets the deadman to 1 and 0 when it’s done.
It seems intermittent on a scope. Probably from proc loop not running at 60 Hz.
Steve is going to think about a hardware fix so 0 volts isn’t full power/full pulse width.
Joe is going to think about how to make a 1/10Hz deadman that looks for a deadman signal within last 0.1 second otherwise turns off RF.
AFG driver code is done
(still true) Ron asked to add this to the list. Need to decide what to do next. Plan to ignore till 4/26. Joe will lend a module to the 2nd floor for testing. Joe imagines we will want to write the function waveform from matlab, which will eventually read in SIS data and decide what to do. This code will probably be EPICSed later.
