---+ How to change beam files

*If you have not had experience with beam files please ask an expert!!!!*

Go on the computer in the other room in which the CESAR program is intalled; go to the top menu: 

Files --&gt; browseFiles and then select files according to what you want; then click on load beam fiIe button

Load both magnets and collimators 

- Electron beam
|H8C.DREAM.022 | 60 GeV | Secondary |
|H8C.DREAM.021 | 20 GeV | Tertiary |
|H8C.DREAM.023 | 30 GeV | Tertiary |
|H8C.DREAM.024 | 40 GeV | Tertiary |
|H8C.DREAM.025 | 50 GeV | Tertiary |
|H8C.DREAM.026 | 10 GeV | Tertiary |
|H8C.DREAM.027 | 6 GeV | Tertiary |

To change from *secondary* to *tertiary*  beam 

Obstacle status -> click on XCON.042.130 (secondary target) to select -> click on move -> choose "12 mm Lead"

To change from *electron* to *muon* beam

Tune -> Set Collimator Jaw Position 
| collimator | electron | muon | 
| XCHV.042.202 | -5, +5 | -20, -10 |
| XCHV.042.203 | -20, +20| -70 - 30 |

In case of problems with a beam file call the CRN operator (75566) or  CCC (77500, 70475) .


----+ Old Stuff
- Pion beam
| File H8C.715 | -180 GeV |

- High Energy wobbling: Electron beam:
| File H8C.746 | -150 GeV | tertiary |
| File H8C.745 | -125 GeV | tertiary |
| File H8C.744 | -100 GeV | tertiary |
| File H8C.729 | -80 GeV | tertiary |
| File H8C.741 | -50 GeV | tertiary |
| File H8C.742 | -30 GeV | tertiary |
Load beamfile with both magnets and collimators For electron insert the TARGET_tertiary if not already in ( go to *Obstacles" -&gt; TARGET_tertiary Air -&gt; Move Discrete -&gt; "Pb_lead (6mm)")

<br />- Electron beam for low energy wobbling (T4.004 H8 -20GeV as secondary beam) *July 2011*<br />| File H8C.729 | -20 GeV | secondary |<br />| File H8C.727 | -15 GeV | tertiary |<br />| File H8C.728 | -10 GeV | tertiary |<br />| File H8C.730 | -6 GeV | tertiary |<br /><br />

- Electron beam for low energy wobbling
| File H8C.752 | -50 GeV | tertiary |
| File H8C.751 | -40 GeV | tertiary |
| File H8C.750 | -30 GeV | tertiary |
| File H8C.753 | -20 GeV | tertiary |
| File H8C.754 | -15 GeV | tertiary |
| File H8C.755 | -10 GeV | tertiary |
| File H8C.756 | -8 GeV | tertiary |
| File H8C.757 | -6 GeV | tertiary |
| File H8C.758 | -4 GeV | tertiary |
Load beamfile with both magnets and *NO collimators* For electron insert the TARGET_tertiary if not already in ( go to *Obstacles" -&gt; TARGET_tertiary Air -&gt; Move Discrete -&gt; "Pb_lead (6mm)" )

<br />      * Chose the following elements: <br />      * Q19 becomes E/60 * (-200)<br />      * Q20 E/60 * (-30)<br />      * Trim9 E/60 * 15<br />   * Example: for 100 GeV e-: Q19=-333A, Q20=-50A, T9=+25A<br />For secondary electron beam:<br />   * Load Collimators<br />   * Remove the TARGET_tertiary if not already out ( go to <b>Obstacles" -&gt; TARGET_tertiary "Pb_lead (6mm)" -&gt; Move Discrete -&gt; Air )<br />   </b> Load Magnets
