DAQ how to¶

on clrlpc, a-compton account

to start coda ( need to be in tcsh )

tcsh
startcoda

several windows will open

click in Control in rcgui pull down connect

select Configuration if not on desired configuration

Hit config , download, prestart and go to start a run

Intelvmeha8 FADC only ( most stable )
FADCTDCDSC : FADC + F1 TDC + readout of discriminator scalers - need to reset and download at each run for now - still need to check

In case ROC or PEB crash, do Ctrl-C in their window and do reset and rcgui and restart a run

To look at data :

on clrlpc :

type tcsh
cd companaEcal
./compana

type run number

type a

type 1 for all events

Open root file in Rootfiles directory

root Rootfiles/vtpCerenkov_795.root

One liner to display all waveforms :

T->Draw("fadc_slot7:Iteration$","")

Look at one fadc channel

T->Draw("fadc_slot7³:Iteration$","")

To display event by event :
i=0
T->Draw("fadc_slot7:Iteration$","Iteration$>200&&Iteration$<600","L",1,i++)

if you go up in history and hit enter it will display next event
