High Speed DAQ for the Active Collimator
High Speed ROOT File Writer
An EPICS IOC server is set up on gluon29.jlab.org:26064 to write the raw waveform data to /gluonraid1/Users/ac directory on demand.
The control of this High Speed DAQ can be found in Hall-D's EPICS GUI:
- Open CSS EPICS Control following these instructions
- From the Main Action Bar under the Beam heading, open the Active Collimator GUI.
- Start or Stop the High Speed ROOT File by clicking the button underneath the title.
- Once started, make sure the a new ROOT file is created and the File Size is increasing. In the box next to ROOT File it should say /gluonraid1/Users/ac/ac_YYYYMMDD_XXXXXX.root.
In very rare occasions, e.g. some one rebooted the AC DAQ server, the writer IOC needs to be restarted
- Reboot using command lines
- Log onto gluon29 using hdsys account
-
telnet localhost 26064 - Restart the IOC by keyboard combination Ctrl+X
- Exit the IOC proServer by keyboard combination Ctrl+]
- Exit the telnet by typing
quit
Analyze the Raw Data
- From Active Collimator GUI
- Click the Analyzer button in the PXI Fast DAQ section.
- From a Linux terminal
- log onto a gluon machine, e.g. gluon30.jlab.org, using account hdops:
ssh -X hdops@gluon30 - enter acanalyzer directory:
cd ~\acanalyzer - start the analyzer script:
./run - in the analyzer, open a collection of raw data files or a processed ROOT file and start the analysis.
List of EPICS PVs
Here are the waveform records with size of 8192, N9 are inner and N10 are outer:
iochdcol:BPM:N9:raw_XPiochdcol:BPM:N9:raw_XMiochdcol:BPM:N9:raw_YPiochdcol:BPM:N9:raw_YMiochdcol:BPM:N10:raw_XPiochdcol:BPM:N10:raw_XMiochdcol:BPM:N10:raw_YPiochdcol:BPM:N10:raw_YM
These are the 16-bit count readings for individual plates that are always available and filtered down to ~1Hz (same order as above):
IOCHDCOL:VMICADC1_1IOCHDCOL:VMICADC2_1IOCHDCOL:VMICADC3_1IOCHDCOL:VMICADC4_1IOCHDCOL:VMICADC1_2IOCHDCOL:VMICADC2_2IOCHDCOL:VMICADC3_2IOCHDCOL:VMICADC4_2
And the gains:
