Software
[edit | edit source]Server
[edit | edit source]The server component of the spectrum analyzer runs on the pc felsax. Its netgate is read by the program Spectrumd and propagated to MQTT.
Operator client
[edit | edit source]Allows changing of server parameters, such as:
- choice of grating
- reference channel
- offset

User client
[edit | edit source]Allows user to view FELIX spectrum, allows limited control of spectrum analyzer (position), allows user to save data to local pc.

SA data viewer
[edit | edit source]Allows user to review captured spectrum analyzer data, export to CSV possible.

Data
[edit | edit source]Each FELIX shot is recorded by the server program, and saved on felixdisk. This data is freely available on the share \\hfmlfelixdisk\hfmlfelixdisk\data\fft\spectrometer (science credentials required). The software SA data viewer can also be found on the same share. Please note that a BASH script on lilo (/home/feloperator/fix_spectrometer_permissions.sh) runs every night at 04:44 and sets the previous day's files and directory to readonly.
Currently, this software is found at \\isolator\lare-rinst\Felix\Felix_prg\UserInterface\sa_dataViewerFelix.exe
Calibration
[edit | edit source]Reduce gun pulse width to make a low-power ! pulse, set spectrum analyzer to zero, and set number of center channel of the spectrum as reference channel.
