Landing Page for the ATLAS In-Flight Beam Wiki

The goal of this wiki is to have access to detector (locations, status, etc.), electronics, hardware, software, targets, and misc, information pertaining to in-flight beam production. The actual data collection and analysis information can be found on the ELOG.

new exp template

Proposed directory / data file structure

New experiments will be placed in ~/experiments/inflXX_zAA (infl12_n16) folder on diag1. Inside folder will have: compass, BoxScore, screenshots, and data directories. BoxScore will be a git repo with current branch = exp name ->infl12_n16. Data will have links to data inside both compass and BoxScore. Data files will have labels (mostly using BoxScore) inflXX__zAA_MonDay_###.root, i.e. infl12_n16_Oct25_0.root

~/experiments/inflXX_zAA
                        /compass --> for all things compass
                        /BoxScore --> (github branch)
                        /screenshots --> for any figures
                        /data --> place for data instead of inside BoxScore / compass....

All data and compass will be backed up on diag3. On diag3 there will also be an experiments folder but only the screenshots will be filled most likely.

BoxScore

BoxScore is a custom made cpp program for "almost" real-time monitoring.

github : https://github.com/goluckyryan/RealTimeReading

program required libaray

CAENComm.h

CAENVMElib.h

CAENDigitizer.h

cern root

program arugments

/BoxScore boardID Location (save_file_name)
                    | 
                    |-- exit 
                    |-- cross 
                    |-- ZD (zero-degree) 

The boardID can be checked by running DetectDigitizer

program running flow

The source code is src/BoxScore.c

1. When started, it read the current date and time from the system, and format the default save_file_name.
2. Based on which Location, it will make a ChannelMask and set the dE and E channels.
3. Read the generalSetting.txt
4. Read setting_X.txt for Channel X setting
5. Open digitizer and setting digitizer from the setting
6. Make root file for saving the data and histogram, Make Canvas for display
7. Readout Loop
   1. check keyboard is hit, get keyboard hit
   2. if start acquisition
      1. retrieve data from the digitizer
      2. every 1 sec (the time period can be set at generalSetting.txt), sorting event based on timestamp, and build event
   3. if stop acquisition
   4. if cut creator is needed, the acquisition will be stop and load the program CutCreator
   5. if clear histogram
   6. if quit

Grafana + InfluxDB

Current setting on June 14, 2019

When BoxScore is running at diag1, it will push the totalRate and (if any) cuts rates to the InfluxDB service at diag1 using

void WriteToDataBase(TString databaseName, TString seriesName, TString tag, float value){
   TString databaseStr;
   databaseStr.Form("influx -execute \'insert %s,%s value=%f\' -database=%s", seriesName.Data(), tag.Data(), value, databaseName.Data());
   system(databaseStr.Data());
}

The databaseName = RAISOR_exit

The seriseName = totalRate / cut1 / cut2 .... etc

The tag = exit / cross / ZD

InfluxDB

InfluxDB server is hosted at diag1.

InfluxDB server can be access via port 8086.

If the InfluxDB server is not started, it can be started by

sudo service influxdb start

Grafana

The Grafana server is hosted at diag3.

The Grafana webpage can be access using any browser

http://diag3.onenet:3000 

The login user name is admin, password is the same as diag3 login.

if the server not started (for example, the webpage is not loaded but connection to diag3 is ok.) it can be started by

sudo service grafana-server start
