MAPMT test with laser, maroc pixel by PC and sum by fadc, at CLAS12 laser test stand



MAPMT test with LED, both maroc pixel and sum by fadc

crate 1 has fadc in slot 3 and ssp in slot 15

15 pmts and 5 fibers 0 - 4

coda data taking

both solid@tunl11 and daq@sbsvme22 use ~/.tcshrc for coda env setup coda config is at daq@sbsvme22:git/rol

to start coda, at solid@tunl11
> vncserver (start vnc)
> vncviewer localhost :1 &  (login with same password of solid user)
inside vnc
> kcoda
> startCoda

If the crate is down, the xterms should have remained up while the crates were down If they are closed, just start them up again. If you think the ROCs need restarted: "restartStuff"

The xterms for the ROCS and PEB should remain up until you kcoda. refer to

when coda running, the processes below are present

coda data analysis



in evio, fadc tag=3, ssp tag=18
maroc sum has sum signal of fadc value as it is, but quad fadc signal needs 4095-fadc, this is like MAPMT simple sum readout

coda output location tunl11:/home/solid/data

maroc analysis

root -b -q 'mRICH_reco.C("/w/halla-scifs17exp/solid/cc_pro/fadc_decoder/solidhgc_67.root" )'

other info

ssp decoding info

For the SoLID Cerenkov test in HallC, maroc electronics will be read out by ssp which can be recorded by coda into evio file

For GEM in HallA/C, it will be readout by ssp also

If we use analyzer to read evio, we would need to make it read ssp bank.

Then interpret its content of maroc or GEM separately.
