NEW MicroMegas chamber monitor - PADME-Experiment/padme-fw GitHub Wiki

by F. Ferrarotto 4/4/2025

All tasks for the monitoring of the micromegas chamber have been integrated into the DCS and start automatically on l0padme1 when starting all other DCS tasks.

To be precise : the readout of the flowmeter, chamber temperature and streaming via webcam of the bubbler are running on one of the raspberry (the one attached to the new camera frame) with the address : 192.168.62.107. You can access this raspberry with ssh -Y [email protected] (password : ask Chiara) from the machines in the DCS area.

The readout tasks should start AUTOMATICALLY when powering up the raspberry and should run continously communicationg with DCS via memcache.

Also the flowmeter control is running there. If you want to access the flowmeter control directory go to padme/flowmeter/python : all scripts are there.

The webcam streaming in real time the bubbler is available at : http://192.168.62.107:8080/stream_simple.html and ts task should be starting automatically at bootup.

The MicroMegas chamber has been integrated in the DCS system and the status can be monitored going in the (OLD) DCS monitor page http://l0padme3.lnf.infn.it:9090/dcs and then in the upper band monitor into

CHAMBER -> Voltages -> CHAMBER-DCS

The page here shows all 12 channels Voltages, currents and status. In the other fields you can see the flowmeter [liters/h] and the DHT22 sensor attached to the side of the camera temp and rel humidity. At the moment all values are updated every ~ 30 sec.
