2014 BL4S Runs

In this section, one can find the run numbers and explanations for all the runs. One can download the ROOT file by simply clicking on the run number.

Tips on Root files

Downloading ROOT

To use root files, you need to install ROOT to your computer. The recommended version is at the following link:
http://root.cern.ch/drupal/content/production-version-534

Windows
If you are using windows, go to bottom of the page and download the windows binary.
It is advised to chose the following: ftp://root.cern.ch/root/root_v5.34.21.win32.vc11.exe
Note: During the installation, select the option "Add root to the system PATH for all users"

Linux
On linux, if you use SLC6 (Scientific Linux CERN), you can install root from software repositories (there is a program called "yum" to install packages in SLC)
In other linux distributions(ROOT should work in any linux distribution.), you may need to install it from source code, which is explained at : http://root.cern.ch/drupal/content/installing-root-source
Note that it may be complicated, and you may ask help if needed.

Analysing data using root files

You may already know how to use root files. We changed some variable names, and made a guide to explain each variable: https://www.cern.ch/test-bl4swebcam/bl4s_tree_explanation.txt

We also wrote a simple example program, to show how to automatically plot histograms from the root file without using "TBrowser" as you have done at CERN. If you are interested, you can try going further to analyse root files writing your own programs, instead of using the graphical interface. In the file, we explain how to use it. Download the file here.

If the information in the below table is not enough, you can go to Electronic Log Book to get more information about the runs.

Going Deeper in ROOT

You can always check root website for tutorials/ guides: http://root.cern.ch

You can also find many tutorials on the internet. A tutorial that can be very helpful is below(It has advanced stuff too)

Online Histograms for Detector and DAQ Shifter

Run Plan of the week

08.09.2014 Monday

1. Install the experimental Setup
2. Install Webcam PC's (multiplugs and extension cables)

09.09.2014 Tuesday

1. Check signals, delays etc.
2. Setup the NIM modules for "other" triggers (muon, electron, muon+electron)
3. Students will have lectures, visits. (We probably are not involved)
4. [DONE]Calibrate DWC with fake signals.

10.09.2014 Wednesday NO beam this day!

1. Introduction to Beamline(Lau) (Two sessions for two groups, morning + afternoon 2h each)
2. Introduction to BL4S Detector/DAQ System and Shifter Training (Two sessions for two groups, morning + afternoon 2h each)
3. Patron training with Lau for Cenk, Saime and Markus.

11.09.2014 Thursday

2. [DONE] Install Dominicus College Calorimeters.
3. [DONE] Check signals from them with muons.
4. [DONE] Check position of each detector, create a new geometry configuration.
5. [DONE]Check signals from all scintillators, try to see if there are noisy ones. Halo Right is noisy, can be changed.
