Mon Feb 22 16:47:28 2016, PJCS, Version 8 in nnaida2 outputting and merging two streams
|
nnaida2 , the bare test FEE64 in T9, is successfully running with two streams connected to nndhcp177 ( a Linux64 computer )
Merge running on nndhcp177 is receiving the streams and merging them.
nnaida2 has a slow pulser , 100Hz , connected to one waveform input. |
|
Mon Feb 22 15:19:52 2016, PJCS, T9 System changed to version 8
|
I have changed the T9 system to be using Version 8.
Tests using the detector and pulser seem to be ok.
Transmission to the Merge and Merging operating ok |

Tue Feb 2 14:08:44 2016, CG, TD, Report: Low - No SYNCs from FEEs
|
Currently running with a source, and everything seems to be running fine in terms of histograms doing what we expect, no error messages etc.
Tried to start the merger and tape server, but the merger reports as waiting for the first SYNC.
Checked the stats page and sure enough, no SYCs are being produced. |
