CODA Startup

  • From an accelerator machine: ssh -X idaq@itfmdaq0

Note: idaq is the injector DAQ account and uses ssh authorized_keys for login - no need to enter password

Execute the following:

% startCoda

Start and Stop a Run

CODA3 desktop.png

From Run Control panel, select in the following order (Note: if any of the selection is already completed, move to the next step):

  1. Configurations => CODA Config => Mott_Sample
  2. Configure
  3. Download
  4. Prestart (or Start. Note that Start combines both Prestart and Go)
  5. Go


To stop a run:

  1. End

To start a new run, select:

  1. Prestart (or Start. Note that Start combines both Prestart and Go)
  2. Go
  3. End

and if you want to apply a change or you need a new configuration:

  1. Reset

and start from number 5.

Configuration File

The DAQ Configuration file is found

  • on itfmdaq0:
   /opt/idaq/itfsbcmdaq0/cfg/uitf_mott.cfg

   ~/cfg/uitf_mott.cfg
