2. 1.Login to the daq01 farm. 2.Input: “../i686-slc3-gcc323-opt/toa ” (Hint: you don ’ t have to type the full path name, you can only type:../i and then press “ Tab ”, the full path name will automatically show up.

3. The TOA GUI is shown, choose any one from the history list or open a new one.

5. Choose the ‘ mean &.. ’, you can see the “ Mean of Q history Data Graph ”

6. Results: From the Q-Ref-DB_2.ps, we can see the sigma of Ref are almost the same, and the mean increase. From the Q-TOF-DB_3.ps, the sigma of TOF counter and the mean increase. The sigma/mean is about 5% at 7.0 intensity. From the T-TOF-DB_4.ps, the sigma decreases as the pulse height increases.

7. Hints: after you run the program and open one file to analysis, you can found these histogram in the tables, they are automatically generated.
