Power outage dates for moving power loads back to the Master SubStation.

A new version of the elog was released 11/22.

- Still recovering from the effects of the partial power outage 2 weeks ago, resulting in sprinkler discharge in FD server room. Experts from Fwermilab & Caltech sent yesterday to start energizing system. Power up started this morning.
ND running smoothly.

When the first 1.2s $2A ramp was tried, MECAR ramped to around 4000A and then tripped off with a No Current Halt. We determined that the PS were not ramping up as they should have.

I remembered that some of the Real Time Events in MECAR have negative time offsets. Upon checking I realized that the Bend Bus Anticipation Event Offset was set to -50mSec. Because the initial DC section of the ramp has been shortened from 80mSec to 42mSec this means the this event doesn't even occur. This is bad.

As a test I shortened the Bend Bus Anticipation Event Offset to -40mSec. This seems to be working.

The quad bus's Anticipation Event Offset had a similar but opposite problem. The Quad Bus Anticipation Event Offsets were set to 69mSec. Because the PS are ramping earlier this was causing the Quad Bus Tier 0 to not turn on in time. I have set the Horz and Vert Anticipation Event Offsets to 10mSec. This seems to be working.

We may have a reboot 07:00 AM Thursday to put in the DirtyCOW security patch.

Our Redmine host and our database are being patched:

This is a reminder that it's patching time again for ccdcvsvm, according to the agreed upon schedule.
Only a reboot is required. Downtime will be <30 minutes.
The system will be rebooted on Thursday, 10/20/16, at 7:00AM CDT.

This is a reminder that it's patching time again for fnalpgsprd, according to the agreed upon schedule.
Only a reboot is required. Downtime will be <30 minutes.
The system will be rebooted on Thursday, 10/20/16, at 06:30AM CDT.

Newest AD Ops Schedule¶

Beam to BNB off November 03, 2016 until ~ 15:30 today.

Plan is to have beam to the MI dump on October 28th and to start low energy target scans on 31st of October.

• Please remember to carry your Fermi Lab ID which will be required for entry, the card readers are operational.****

Network redundancy project is complete¶

The first, second and third phase of the project is complete as of Monday 09/12/2016.
ROC West now has a more robust Network connection via Feynman Computing Center.

A good fraction of the code is documented and this documentation appears in the html pages generated by Doxygen. HighLAND also comes with a set of Doxygen files explaining the features of the framework. This is the strategy adopted for T2K and is now being imported to DUNE. The web documentation generated by Doxygen is temporarily available at http://www.cern.ch/acervera/highland
