i am interested to know about the tech stacks of the website i.e., how the data is displayed

it's just an img tag with an image that is updated a few times per minute, guessing it's a screenshot of some sensor terminal at cern? :D

Probably not

Many old monitoring programs just literally generated graphs like these using input data and outputted a static image on a cron/tick. "Expensive" once, then cached... in the form of the image

I'm guessing this is that sort of tech

These are screenshots taken from SCADA screens.

Architecture briefly explained here: https://accelconf.web.cern.ch/ica05/proceedings/pdf/O3_005.p...

I also want to mention EPICS which is used by quite a few physics and telescope projects: https://epics-controls.org/epics-users/projects/

When CERN Was looking at software they found EPICS wasn't up for the task at the time: https://cds.cern.ch/record/532705/files/ma1o06.pdf

The LHC also has a public Grafana (mostly for cryo stuff): https://dash.web.cern.ch/dashboards/

And there used to be a very fancy LHC dasboard at http://meltronx.com/index.html

Unfortunately the site breaks with HTTPS and modern browsers (mixed content isn't allowed anymore, and they never updated it). It has to be http://.

What are they looking for at the moment?

The LHC is a discovery machine, so a large number of searches for new physics as well as measurements of known physics can take place at the same time.

The idea that it is a single-trick experiment is a misconception. Its a quantum statistical experiment where proton collisions at high energy yields random particles based on the probability of specific interactions taking place.

This is unnecessarily dismissive. Even the grants themselves will include a list of things they hope to discover or measure with this refresh; this is a perfectly reasonable question to ask.
