In order to run the combined S800 + Gretina daq, the following steps need to be taken:
Start
button. godaq
to run the Readout control program.Start
button. This will grab remote control over the S800 Readout GUI.on the dual homed system.
When everything has started correctly you should have the following ring buffers in the dual homed system (e.g. ddasdaq3):
* experimental-user-name (e.g. e14045) this ring is where sampled coincidence data
is placed. This is done via a tapcat, glom pipeline.
* spdaq19.rawccusb - will provide raw data from the S800 CAMAC crate. * spdaq19.rawvmusb - will provide raw data from the S800 VME crate. * spdaq19.s800filter - will provide the event built, reformated data from the
S800. During a run, data are pushed from this ring into the GRETINA GEB.
In addition to the normal stagea are structure three directories are added that will be used to store raw S800 data:
* stagearea/rawccusb - Event files containing raw ccusb data from the s800. * stagearea/rawvmusb - Event files containing raw vmusb data from the s800. * stagearea/s800filter - Event files containing event build, reformatted
s800 data.
1. On spdaq48 in /user/s800/operations/daq/usb/TclXXUSB do:
wish ./RunControl.tcl
or, on devop2 (the S800 MAC machine)
click on the operations folder on the lower icon bar and select runcontrol.command
2. On a dataU machine logged in as the experimental account (e11007 for the June 2012 testing period) do
godaq
3. On spdaq44 do:
/usr/opt/daq/10.1/bin/ringbuffer status. The output should look similar to:
+----------------+------------+-------+-------------+--------+---------+---------+------+-------------+ |Name |data-size(k)|free(k)|max_consumers|producer|maxget(k)|minget(k)|client|clientdata(k)| +----------------+------------+-------+-------------+--------+---------+---------+------+-------------+ |0400x |8195 |8195 |100 |-1 |0 |0 |- |- | |s800 |8195 |8195 |100 |7485 |0 |0 |- |- | |- |- |- |- |- |- |- |9143 |0 | |segatest |8195 |8195 |100 |-1 |0 |0 |- |- | |spdaq48.0400x |8195 |8195 |100 |17205 |0 |0 |- |- | |spdaq48.segatest|8195 |8195 |100 |-1 |0 |0 |- |- | +----------------+------------+-------+-------------+--------+---------+---------+------+-------------+
Upon start of run there will be another client of the s800 ring, which is the pushToGEB process. This should die on end run.
The S800 daq will now be in slave mode, and run control is done from the NSCL daq window.
