sPHENIX discussion of physics

[Xiaochun He <xhe AT gsu.edu>]

Dear Martin,

Thank you for taking your time and promoting the rcDAQ users community in sPHENIX. I also want to thank you again installing rdDAQ on our sweet PI's at GSU. 

We are very interested in populating your new PI 3 image if it is available and could even maintain a VM node if it is not too complicated.

cheers,

Xiaochun

Subject: Re: [Sphenix-physics-l] Introduction to data taking at the FermiLab test beam

 

Dear all,

thanks to all the 24 brave souls (yes, Bluejeans knows who you are) who
stayed through the entire meeting that was running much longer than I
had anticipated. I hope it was useful.

I have uploaded the powerpoint file as promised (the upload had gotten
stuck yesterday). I also added a link to the recording of the session so
you can see the demos I made.

https://na01.safelinks.protection.outlook.com/?url="https%3A%2F%2Fwww.dropbox.com%2Fs%2Fsjtw4ai4qxc07qn%2Frecording.mp4%3Fdl%3D0&data=01%7C01%7Cxhe%40gsu.edu%7C6b85800ee3874d7395c708d43af12161%7C515ad73d8d5e4169895c9789dc742a70%7C0&sdata=HUkHa0JAltxvUlXjwwqF%2BQF74h3mkcJALaXq09ooFFQ%3D&reserved=0

I mentioned the virtual machine yesterday, and it turned out that many
people were not aware of it. It is true, the interest in it has waned,
and the current version is rather dated (2015). Also keep in mind that
its main purpose was to give you a way to play with Geant4 quickly at a
time when versions were updated quickly, and many people were just
coming on board and had no real place to do so. All the Geant4 libraries
and data files, and the fact that we added pretty much the entire
software universe make the downloadable VM a rather big 3.3G affair.

For full disclosure, a working version info is below. *However*, you'll
get a pretty old (and, if you only want to run the tutorial, bloated)
machine. Maybe I'll make a lean, ready-to-run-RCDAQ modern version of
the VM. (All demos were run on a VM on my Mac yesterday.) Give me a bit
of time to do so.

Also, I could distribute a Raspberry Pi image with everything
pre-installed if there is interest. If you have the latest RPi3, you
could run cool things - I actually managed to install root on the Pi so
you can run the entire show there. (Including the infrared remote thing
if you invest $2 in a receiver :-) ) RCDAQ itself runs on any Pi, root
requires the latest model. Let me know if anyone wants this.

Also if someone is interested in maintaining up-to-date VM versions as a
community service, it would be a big help.

Thanks again for your interest yesterday.

        Martin
