---+ <B>Silly shifter questions & regulations </B>
 
---++ Before shifts: what to do ?

Before the shifts start: <BR>
<ol>
  <li> check your access rights to ATL_CR (Atlas Control Room) <BR>
  <li> look througt the most recent LBCF, LUCID, ZDC, BCM instructrions:
  <BR>
  http://pcatdwww.cern.ch/twiki/bin/view/Main/BeamConditionsOperationManualShifter
  <BR>
  http://pcatdwww.cern.ch/twiki/bin/view/Main/LUCIDOperationManualShifter
  <BR>
  https://twiki.cern.ch/twiki/bin/view/Atlas/ZDCShifter
  <BR>
</ol>

If need to contact the LBCF shifts coordinator in a harry, look for the phone here.

---++ <B> Atlas Control Room (ACR): How to find it?</B> 
    <ol>
         <li> <font size=+0 color="#000000">[[http://building.web.cern.ch/map/building?bno=3162][ Building Location ]]</font>
         <li> <font size=+0 color="#000000">[[http://atlas.ch/webcams.html][ Web cams ]]</font>
    </ol>

---++ <B> IMPORTANT: try to speak in a low voice !</B>
Please try <b>to speak in a low voice</b> with your desk(s)-colleagues so long you are in the control room !
IMHO: this should became an official prescription in the shift regulations, that only a shift leader 
would speak loudly among 20-25 shifters. It is rather hard to stand for several hours many various 
discussions around neighboring desks.

---+ <B>Computing questions & problems </B>

---++ <B> Computer on shift: pc-atlas-cr-03</B>
<P>
<b>pc-atlas-cr-03.cern.ch</b> &nbsp; (IP:  10.144.36.252)<P>
This computer has many restrictions to use the web and not allows to arrange the bookmarks. :(


---++ <B> Proxy configuration for the firefox</B>
<P>
In Mozilla-firefox window open "Edit" --> "Preferences". <BR>
In the "Firefox Preferences" pop-up window go to the "Network" folder and press "Settings..." button.<BR>
In poped-up "Connection settings" window select "Automatic proxy configuration URL" <BR>
and fill there: <b> http://atlasgw-exp.cern.ch/proxy.pac </b>

---++ <B> Copy files to / from Point-1. How?</B>

You could have  a look in [[http://atlas-tdaq-sysadmin.web.cern.ch/atlas-tdaq-sysadmin/documents/Atlas_Point1_FAQ.html][Atlas Poit1 FAQ]] page,
but better just follow this simple and clear examples:
<BR> From point-1 computer to lxplus.cern.ch:
<BR> <b>[lxplus]$  scp -p user_name@atlasgw:/atlas-home/1/user_name/file_to_copy</b>
<BR> From lxplus.cern.ch to point-1 computer:
<BR> <b>[pc-atlas-cr-03]$  scp -p    file_to_copy    user_name@atlasgw:/atlas-home/1/user_name/.</b>
<BR>The <b>atlasgw</b> is a cluster of gateway computers. (You can check with: <b>ping atlasgw.cern.ch</b>)

<u>Time needed:</u> ~45-60 minutes ! (~ 15-20 min. for pedestals + ~30-40 min for calibration)<br>
</font>
<P><br><P>
<b><u>Before taking Pedestals & Calibration run:</u></b>
 <ol>

    <li> There is no need to check Lucid HV settings being on shift. <BR>
     The HV settings which must be appropriate to the current B-field configuration are set AUTOMATICALLY under the experts care.

    <li>  make sure LUCID is disabled from the ATLAS partition <br>
           If RUN is stopped, all subsystems must be marked in grey color on the DAQ monitor.
           If you are not sure that  LUCID is disabled then ask the DAQ shifters.

    <li> Setup the DAQPanel as follows:<br> 

    <ul>
         <li> <i>Setup script</i> :      &nbsp;  <b>/det/lucid/tdaq-02-00-03/setup_calib.sh</b>

    <li> Click on  <b style="padding:5px;border: 2px solid #999999";  BGColor="#112299">Read Info</b> button. <br>
          The tabs on the right side of the DAQPanel will be activated and colored. 

    <li> Wait a bit these tabs are activated.

    <li> Click on tab  <i style="padding:5px;border: 2px solid #999999";  BGColor="#112299">StartPartition</i> 

    <li> Wait for the pop up "RunControl GUI" window to be displayed. (This should take around 10-20 seconds)

</ol>


<b><u>Take the pedestals run:</u></b>

<ol>

    <li>  In the pop up "RunControl GUI" window look for the <b><i>Run Information & Settings</i></b> panel (left, middle)

    <li>  Click there on the <b>Settings</b> tab at the bottom of the <i>Run Information & Settings</i> panel<br>
           to set parameters for the pedestals run:

       <ul>
           <li> Set "MaxEvent" to <b>300 000</b>; (the run will stop by itself when done)
           <li> Select "RunType": <b>Pedestals</b>;
           <li> Beam type: "No beam" or "Protons";
           <li> Beam energy: put value in "GeV" if any;
           <li> Tier0 Project Name: <b>data09_calib</b>
           <li> "File Name Tag":  write <b><i>pedestals</i></b>;  (DO NOT USE dots, blanks and other special symbols)
           <li> Recording: mark "<u>Enable</u> writing of the output file"; <P>
           <li> Click on the <b style="padding:5px;border: 2px solid #FF0000";  BGColor="#112299">Set Value</b> 
                red box to commit changes;
       </ul>

    <li> Follow the <b> &nbsp; BOOT &nbsp;  &rarr; &nbsp;  INITIALIZE &nbsp;  &rarr; &nbsp; CONFIG  &nbsp;  &rarr; &nbsp;  START </b>
          procedure <u>carefuly</u>  <BR>  from the <i><b>Run Control Commands</b></i> panel (top left) of the  "RunControl GUI" 
        to start the pedestals run.

     <li> when the run actually starts, a pop-up window will appear asking you to enter details about the run in the E-LOG. 

     <li> Write the details of the run here like: "pedestals". Put extension information if needed.

    <li> Check the pedestals run progress<br> 
          under the <b>Counters</b>  tab of the  <i>Run Information & Settings</i> panel  inside the "Run Control GUI".

    <li> press OHP button on the DAQPanel <br>
     to check everything is fine looking at the histograms. Pedestal histograms should show 
     gaussian-shaped distributions. Beware that different histograms are filled at different time, 
     so that at least 5 minutes MUST elapse before you can see ALL histograms.

    <li> Wait untill pedestals run will be finished collecting ~300 000 events.

</ol>

<b><u>Take the calibration run:</u></b>

<ol>

    <li>  In the "RunControl GUI" window look for the <b><i>Run Information & Settings</i></b> panel (left, middle)

    <li>  Click there on the <b>Settings</b> tab at the bottom of the <i>Run Information & Settings</i> panel<br>
           to set parameters for the <b>calibration run</b>:

     <ul>
         <li> Max Events:  put zero-value: <b>0</b>. 
               This "0" means, there is no max. number of events to collect and you must control the collected statistics by yourself.
         <li> Run Type: Select <b>CalQDC</b>.
         <li> Beam type: "No beam" or "Protons";
         <li> Beam energy: put value in GeV if any;
         <li> Tier0 Project Name: <b>data09_calib</b>
         <li> File Name Tag:  type in: "calibration", or something like this. AVOID dots, blanks and other special symbols !
         <li> Recording: mark "Enable writing of the output file" 
         <li> Click on the Set Value red box to commit your changes 
     </ul>

     <li> Let calibration running for 30 minutes or so to collect enough statistics.
            You'll have to stop the run: either once all histograms have at least 150000 entries , 
            or when you can see new points in the DCS trending plots.

      <li> Calibration histograms should show single photo-electron spectra. <br>
            Beware that different histograms are filled at different time, so that at 
            least 5 minutes MUST elapse before you can see ALL histograms.

     <li> At the end of each run, results are sent to DCS. 
     <li> Look at the corresponding trending plots in the LUCID DCS display to make sure nor 
           the pedestal MEANS or the pedestal RMS changed significantly from previous runs. 
           If so, please WARN the TDAQ-Expert (16 2443). 
           Calibration values ought to be around 15.
