Basic Information
A PXI system is built and configured to monitor the vital signals of the Hall-D super-conducting magnet to ensure its safe operation, particularly to detector the turn-to-turn short faults. Currently, the system contains 4 ADC modules which can sample up to 32 channels simultaneously at a maximum rate of 250 kHz. A LabVIEW RT program is automatically loaded and executed when the system is booted as a stand alone turn-key system. Through its Ethernet connection, the system hosts an EPICS server so that the measurements can be easily accessed and archived remotely. It also serves as an Ethernet device to the magnet control system based on PLC to provides various readings including current, field and voltages.

How-To
Check PXI Status
Reboot PXI Chassis
High Speed DAQ
Analyze High Speed Data
- log onto a gluon machine, e.g. gluon30.jlab.org, using account hdops: ssh -X hdops@gluon30
- enter the solenoid directory: cd ~\solenoid
- start the analyzer: ./analyzer
- in the analyzer, open a collection of raw data files or a processed ROOT file and start the analysis.
