Steps for taking Data
In order to take cosmic-ray data, you must follow these steps:
Prototype II has two sets of high voltage power supplies (one for the
scintillator trigger and one for the DCH wires), a low voltage supply for
the front-end electronics, and a few independent crates.
- Log on to Proto II Workstation
- Turn On the Power Supplies
- Start the DAQ program
- Start the Run
- Stop the Run
Steps to be followed
1.Check water level in the chiller.Maintain water level in the chiller such that thermometer is dipping in the water.Start the chiller when this done.
2.Put the power on for Low Voltage.
3.Put the power on for High Voltage.
4.Check the Proto II chiller status.Green light indicates water is flowing.Red light indicates water is not flowing.
in the terminal window.
2.After step1 is completed, Enter
3.After step2 is completed, Enter
4.A small window will appear on the screen having two options.
Click on ROC26.
5.After step4 is completed, Enter
6.Another small window will appear having three options.
b)Run Calibration on the ROM
click on Reboot.Then Run Calibration.
7.Enter configuration key as
8.Check if it runs successfully.If no,then try to fix the errors.
1.In the terminal window, enter
2.Two windows will appear.
3.Check if the event level is completed successfully.If yes,type exit.This will make the event level ready.
4.Hit return in the control level window if step 3 is completed successfully.
5.Once steps 3 & 4 are completed successfully,we will get a window named Dataflow Finite State Machine Manager.
6.Click on Configured (Not the arrow but words)
7.Enter value of allchan.dat in environment as
0xffffffff in triggerlist to show all triggers.
1.Click on the arrow showing configured.Check if the control level window shows any error message.If yes,then try to fix the error.If not,then follow the arrows.
2.Once all the arrows are followed,quit the window.
3.Check if any error messages are there in control window.If yes,try to fix it.If no,quit the window.
4.Data taking has been successfully completed.
