Digitizer
[edit | edit source]
Pyro digitizer hardware in the rack
The digitizer itself is a Bitscope micro board, attached via usb to the pi.

Software
[edit | edit source]Pyrod takes the digitized signal of a pyroelectric detector in the diagnostic station and publishes the trace, together with an integral value, to the felixbroker. The FELIX pyro can be restarted using the monit instance on pi7.

The pyro trace is represented as a string of 512 floats that are separated by commas. The datapoints are are sampled at 20 MHz (i.e. are spaced 50 ns apart) and are expressed in units of Volts.

Client
[edit | edit source]There is an experimental client GUI that can be found here: S:\Felix\Felix_prg\Operator pyro and spectrum\plotter.exe. It is meant as a tool for the Operator to keep track of the performance of FELIX from his/her desktop.
Installation
[edit | edit source](work in progress)
apt install python-is-python3 python-dev-is-python3 python3-pip
First, make sure you have set up Feloperator gitlab authentication for the git clone and pip install commands below to work.
