Specific Instructions for Experiments

ISS Experiments

• ELOG [1]

iss000-development, mg28 [Sharp, 09/2018], hg206 [Kay, 10/2018]

DAQ Information

• Information on rebooting the DAQ can be found here :System use and a video specific for the iss experiments is here [2]
• Video showing how to start a run and what the DAQ looks like when running can be found here [3]

Array High Voltage Control

• Video to show starting up the Si Array HV can be found here [4]

Computer Information

• DAQ Computer - linux box mounted in the daq crate for daq control. Sits under the NAT BOX (helios @anldaqrouter std pswrd).
• MAC Computer - for analysis and remote login control of the DAQ Computer (heliosdigios @anlanamac NOT std pswrd - lowercase name of device at ANL).

Software Information

• lumped all software [daq control, sorting, monitoring, etc.] to a single git repo [5]
• Cloned versions of git repo on MAC at ~/experiments/iss000 and on DAQ at ~/experiments/iss000

To start the daq Commander on the DAQ Computer:

gotodaq (or cd ~/experiments/iss000/daq)
./helioscommander

To sort data on the DAQ (local) Computer (anldaqrouter): First go to the working analysis directory, then start sorting process on run of interest (ok to do this on run that is currently taking data). This will do a number of different things: 1) it will first run the GEBMerge program (GEBSort director) to combine and timesort all raw data and outputs to the merged file. Then it will run GEBSort (GEBSort directory) which is the event builder and outputs to a .root file. Finally, it runs the TSelector GeneralSort.C (sort_codes directory) which passes the raw data into the human-readable names, e.g., xf, xn, e, etc...A copy of this file is placed in the ../root_data/ director (gen_run#.root). The most recent gen.root file is also in the working directory.

gotoana (cd experiments/iss000/analysis)
cd working
./process_run_local.sh <RUNNUMBER>

The above process will continue to run until it is killed (Ctr-C). A good time to do this is when it says, XXX seconds until next sort...You can look at the gen_run#.root file manually at this point. Otherwise, you can run the following to generate a few pre-made histograms and canvases.

root -l ../root_data/gen_run#.root
gen_tree->Process("../sort_codes/Monitors.C++")

Then you have the filled histograms. You may also do the following for example after the Monitors.C has finished.

.L ../sort_codes/Utils.C
listDraws()

Will show some of the pre-made canvases and draw functions.

To sort data on the MAC Computer: Sorting data on the MAC Computer (anlanamac) is very similar to the local daq sorting with a couple of small differences. Namely, you have to pull the data locally first before sorting (which requires typing of the password each time), and also, the sort does not continually run. So each time you want to look at the data collected you have to run the (./process_run.sh ##).

After logging into the MAC Computer (heliosdigios@anlanamac)

gotoexp
cd working
./process_run.sh <RUNNUMBER> 
<ENTER anldaqrouter PSSWRD>

Now you will have the GEBMerge, GEBSort, and GeneralSort's completed and a local gen_run#.root file available. You can make the histograms same as before with this.

root -l ../../root_data/gen_run#.root
gen_tree->Process("../sort_codes/Monitors.C++")
.L ../sort_codes/Utils.C
listDraws()
xfxn()

h061_mg26 [McNeel, 3/2018]

Analysis directory on the iMAC [gotoexp]

~/experiments/h061_mg26

To process a run on the iMAC

gotoexp ; cd working
./process_run.sh #

Where # is the run number of interest. This command will first pull the data from the DigiOS computer:

get_digios_data #

Then merge all data in a time-sorted fashion:

gebmerge.sh #

Then events are created based on the input file GEBSort.chat

gebsortmerged.sh #

The output file is run#.root. Finally, a general sort is carried out to map the data into the proper HELIOS parameters:

root -l ../root_data/run#.root
tree->Process("../codes/GeneralSort.C++")

or

root -l proccess_run.C(#,0)

The output file is gen.root which is copied to ../root_data/gen_run#.root

To generate the monitor spectra, you can run:

root -l ../root_data/gen_run#.root
gen_tree->Process("../codes/Monitors.C++")

Note, that the GeneralSort.C and Monitors.C are located on the svn at

https://svn.anl.gov/repos/helios/DigiOS/SiDet/trunk

A new branch for all of the DigiOS DAQ control software is here:

https://svn.anl.gov/repos/helios/DigiOS/edm/branches/h061

Data is stored locally on the DigiOS DAQ Computer at

/media/DIGIOSDATA3/data/h061_mg26

and a copy will eventually be available on the iMAC at

~/experiments/h061_mg26/data

H060_Pb208 [Kay, 3/2018]

There is an ELOG.

New branch for all of the DigiOS stuff has been made.

https://svn.anl.gov/repos/helios/DigiOS/edm/branches/h060/

Local working directory on MAC

~/experiments/h060_pb208

Data is saved on DigiOS

/media/DIGIOSDATA2/data/h060_pb208

H057_He6 [Chen, 8/2017]

To Do List

• Needs for beam testing
  • Control of the digitizer channels for setting threshold, trigger, etc
  • A way to quickly process and view the data for beam tuning [online, offline, etc]

• Needs for experiment
  • Mapping of the signals [new more simple map?]
  • Look into data readout
  • Better online monitors
  • Fix for GEBSort_nogeb on MAC

Locations

daq control - /global/devel/systems/helios/h057 data - /media/Digios Data/data/h057_he6

Take Data

In the directory that you would like the data to be saved on the digios daq computer, execute:

start_digios_run <run #>

stop_digios

Move Data In the directory you want to put the data on the MAC computer

get_digios_data <run #>

Sorting Data

sorting the root file uses codes located in svn.anl.gov/repos/DigiOS/SiDet/trunk

H054_F21 [Chen, Hoffman, 4/2017]

Locations

Sorting the data

• cp data from digios1 daq computer location /media/Digios Data/data/h054_f21 to malaguena data location /music/helios2/H054_F21/digios/data

1. cd /music/helios2/H054_F21/digios/data
2. rsync --progress --protect-args --size-only -avzPe ssh "dgs@digios1:/media/Digios Data/data/h054_f21/h054*" . [NOTE: not sure this gives you the fastest transfer speeds CRH 8/17]

• merge data files from malaguena working directory /music/helios2/H054_F21/digios/working

1. ./gebmerge.sh RUNNUMBER

• sort the data files from malaguena working directory

1. ./gebsortmerged.sh RUNNUMBER

• generate general root file from malaguena working directory

1. root -l ../root_data/h054_runRUNNUMBER.root
2. tree->Process("../codes_trunk/GeneralSort.C+")
3. creates gen.root file in working directory

• generate Monitor histograms from malaguena working directory

1. root -l gen.root
2. gen_tree->Process("../codes_trunk/Monitors.C+")
