How to run CODA

  • Log into idaq@opsmdaq0 (It is an accelerator machine!) using the idaq account and open few terminals. The xterm command will help you on that
 in xterm 1: telnet iocmdaq1

 in xterm 2 : platform

Telnet is used to control the status of the run, error messages are appearing here!

  • In another terminal type :
 in xterm 3 : codamaster

Choose one of the configurations.

When the CODAMASTER panel appears, select config => enable buttons.

Select ET System, Event Builder and Event Recorder. and Run Control to monitor and operate runs. After doing that if you will click on Get Status you will find status of Event builder Event Recorder and of the ROC1. Al buttons must be green as the picture is showing.

Selecting Run control the main CODA panel will appear.

Start and Stop a RUN

After the opening of the Run control panel, select in order:

  1. Sessions => inj
  2. Configurations => Cool => Choose the wanted one
  3. Platform => Connect
  4. Configure
  5. Download
  6. Prestart
  7. Start the run

as displayed in the picture:

At the end:

  1. Stop

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

  1. Reset

and start from number 5. When you are applaying a reset, do it twice (suggestion).

Errors, Warnings and FAQ

How to use the VME discriminator

The VME discriminator is the CAEN v895 whic has several possibilities. It is used in several configuration file but it must be set up correctly. The configurations used, at the moment, are:

  • PEPPo_Sample, PEPPo_Cosmics, Annihilation_Sample, PEPPo_SemiInt

How to use the module, from every directory: 

  v895_config

An user interface will appear.

PMT refer to PEPPO cristal PMTs, A1 and A2 are for annihilation counter and cosmics are for cosmic paddles.

  • Set thresholds for all the channels (thresholds are in mV) and select(tick) only channels used.
  • To set the number of channels used as to generate one trigger select the Majority Level (MJL) or coincidence.

MJL = 1 means that, with at least one detector above the threshold, it generates the output signal. MJL = 3 you need at least 3 detector signals above the thresholds to generate the output signal

For Cosmic and Annihilation configurations MJL set to 2.

To close Coda use the codamaster panel and press kill all followed by the exit botton under 'configuration'.


How to use the JLAB VME discriminator

One can open a GUI in from opsmdaq0
