Newbie Material

All of SBND's material can be found on the docDB. It requires a password to access everything, just ask for it!

To be part of the SBND-software mailing list send an email to: with the following information: SUBSCRIBE SBND-SOFTWARE YOUR NAME. Here is a list of all the mailing lists available: https://listserv.fnal.gov/scripts/wa.exe?INDEX. For more information see: http://listserv.fnal.gov/users.asp#subscribe

Computing Access

See the Computing resources page to see a discussion about the computing privileges that SBND has.

To get a Fermilab computing account follow the instructions at this site. Our experiment number is T1053

Write down the initial Kerberos and Services Account password before submitting. This will be necessary once your accounts have been created.

You will receive an email once this is complete which gives you your Fermilab email account and username (you will need this for service now).
Once your computer is ssh ready and kerberized, you should be able to log on by typing:

kinit  [yourusername]@FNAL.GOV

ssh -Y [yourusername]@sbndgpvm01.fnal.gov

Note that you need to have the right configurations, add the following to your machine's ~/.ssh/config 

Host *.fnal.gov
  ForwardAgent yes
  ForwardX11 yes
  ForwardX11Trusted yes
  GSSAPIAuthentication yes
  GSSAPIDelegateCredentials yes

Create the file if it's not there. In some systems you might need to reload the ssh agent. You also want to have this file in the gpvm machine.

If this does not work, please submit a service desk ticket to request a SBND project account (I believe someone has to authorise this so it will probably fail)
ServiceNow-> Request Something -> Experiment/Project/Collaboration Computing Account

Enter your name, then select T-1053 (SBND)
Verify that the correct Fermilab principal is displayed when you enter your name
Enter your home institution, then click Submit.

You can reset your Fermilab passwords for service-now here.
If you can't remember your password because you didn't write it down then you will have contact the service desk.

Communication and Asking for Help

We use different technology to communicate, depending on the purpose and type of communication.

  • Emails are used to send announcements, call for meetings or other events and, in general all important communication that shouldn't be missed goes through emails. Sign in to SBND mailing lists by sending an email to with no subject and in the body put: SUBSCRIBE NAME-OF-MAILING-LIST Name Lastname, for example I would write: SUBSCRIBE SBND-SOFTWARE Iker de Icaza.
  • Slack is used for day to day communication, particularly useful if more than one could answer --remember SBND collaborators span several time zones-- or if the answer could benefit more people than just you. Once you have a FNAL account sign-in to SBND Slack with you FNAL account.
  • Zoom is used for meetings, you will need to have it installed on your computer. You don't need to make an account to use it, however if you open it with your FNAL email you can see Fermilab's rooms listed. Pro Tip: configure it to start meetings with no video and muted, also but less important, put your name as you would like it to appear to others.

New to Liquid Argon Technology/ Neutrino physics and SBND?

If you are new to Liquid Argon technology then here as some links you might find useful:

Stolen straight from the 35 tonne page:

The SBN Proposal: A Proposal for a Three Detector Short-Baseline Neutrino Oscillation Program in the Fermilab Booster Neutrino Beam

The MicroBooNE

The ICARUS publications: http://icarus.lngs.infn.it/publications.php

Here is a list of publications/books that people have found useful. Please add to the list!

New to the Software Surrounding SBND?

To get started you need to have a basic knowledge of c++ and you need to learn LArsoft. Root and Git are also useful.

Art and LArsoft

Here is a few places to look at more information about Art and LArsoft.

  • LArsoft: Training sessions (This a link to some useful presentations introducing LArsoft).
  • The Analysis Examples: This is a package that can be downloaded into your local library. Follow the same procedure as in: How to setup your directory and launch your first job but instead of mrb g sbndcode do mrs g larexamples . You can download the package with these steps:
 mrb g sbndcode

Do

 mrb g larexamples

The g is short for gitCheckout.

C++

There are a multitude of resources for c++. There are several books. The one I learnt form was Accelerated C++ .

For online resources Stack Exchange is useful so is cppreference. If you have a good c++ tutorial/documentation add it to the list!

ROOT

ROOT is also useful to know and it can be used within LArsoft. If you are new to ROOT and you have a bit of time to learn it I recommend the Nevis tutorials. Given, is an estimated time to complete each section so you have a good idea how much time the whole tutorial takes. The ROOT pages are powered by doxygen and are useful for finding information about specific functions or finding a function you need. Below is a few more places that are useful when learning ROOT. Feel free to add to the list!

  • The Root Tutorials: https://root.cern.ch/root/html/tutorials/ (A very good list of different example macros in root, there is less explanation of how things are working but it gives you something to work off)

Git

New to Git? if so do the quick tutorial to get an idea of how it works. To see how it used in SBND see the Working on a feature branch (to easily share code).

Pro Tip: Log into a gpvm node and do the following commands to setup your git account:

git config --global user.name "Name Lastname" 
git config --global user.email "user@fnal.gov"

With this you will have your commits signed by you and listed neatly on your Redmine account. You CAN list another email other than your FNAL one, but you need to change it accordingly on your Redmine account.
