Specific Instructions for Experiments

ISS Experiments

• ELOG [1]

iss000-development

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 Computer:

To sort data on the MAC Computer:

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+")
