Mon Mar 31 16:53:03 2025, Shahab, DAQ, stop and delete NTCAP data from Weekend test
|
stop and delete NTCAP data from Weekend test
for now the NAS data2 bank has been flushed to make sure good operation for today's beam.
we have now 35 TB space on bank 2.
the recording will be done on the bank2 of the NAS.
There are still some junk data on bank1, which we will remove later. |

Mon Mar 31 17:46:21 2025, Esther, DAQ, NTCAP scaler assignment
|
The setup contains two NI-6612 I/O cards with BNC-2121 connector accessories that provide eight inputs each for TTL scaler signals.
Important: When connecting scaler signals make sure that they are TTL (not NIM)!
Additionally, there is the possibility to assign data streams (eg clocks) from other modules in the NI chassis to scaler channels.
Below you find the assignment of the channels on the software side, including the internal clocks. This is important when analysing the .tmds files.
|
Channel | Input | Comment
| |
0 | 10 MHz clock | external (from NI 6674T timing module)
| |
1 | DC trafo | ion current in ESR
| |
2 | injection trigger | from Genesys (IO2 on sddsc221)
| |
3 | U-cooler | cooler voltage
| |
4 | I-cooler | cooler electron current
| |
5 | P-gun | pressure at e-cooler
| |
6 | 100 kHz clock | internal
| |
7 | 20 MHz clock | internal
| |
8 | software trigger | from Detectomer
| |
9 | PLEIADES outside |
| |
9 | PLEIADES inside |

Tue Apr 1 02:55:06 2025, Shahab, Michael, Yue, Zac, Carlo, DAQ, new RSA recording
|
anything from RSA01-2025.04.01.02.54.25.976.tiq onwards is good data
recording parameters:
5 MHz with 6.25 MSPS, 2.5 seconds, analyzer span 100 khz, trigger at 5%
All analyzer times are now set to summer time
file time stamps are correct
settings are in the attached pictures. |

Last file from previous setting: RSA01-2025.04.01.21.06.30.580.tiq
Changed the RSA01,02 to 50 MSamples/s (20nsec/sample) for 500.00 ms acq. length, 25 MHz acq. BW, 33% trigger position.

Tue Apr 1 22:03:07 2025, Jeroen, Zac, Esther, Shahab, Wolfram, DAQ, Optimisation of settings
|
Estimation of potential gain by changing. Files from this points are going to rubbish. Potential gains are c. 20%
22:04: The current acquisition window is recording for 2.9 s. And is not recording for 3.9 s. We are running currently with a spill cycle of 5s every repetition.
22:22 The spill cycle between each injection was changed to 4->3->2s progressively and FRS also stopped taking spills so we settled on 2s spill request.
In the morning the spill request has to be changed back to 5s when the FRS goes back into operation.
new file with the setting is
RSA01-2025.04.01.22.19.06.761.tiq
