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 --> browseFiles and then select files according to what you want; then click on load beam fiIe button
Load both magnets and collimators

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

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

Load beamfile with both magnets and collimators For electron insert the TARGET_tertiary if not already in ( go to *Obstacles" -> TARGET_tertiary Air -> Move Discrete -> "Pb_lead (6mm)")

- Electron beam for low energy wobbling
Load beamfile with both magnets and
NO collimators For electron insert the TARGET_tertiary if not already in ( go to *Obstacles" -> TARGET_tertiary Air -> Move Discrete -> "Pb_lead (6mm)" )
* Chose the following elements:
* Q19 becomes E/60 * (-200)
* Q20 E/60 * (-30)
* Trim9 E/60 * 15
* Example: for 100
GeV e-: Q19=-333A, Q20=-50A, T9=+25A
For secondary electron beam:
* Load Collimators
* Remove the TARGET_tertiary if not already out ( go to
Obstacles" -> TARGET_tertiary "Pb_lead (6mm)" -> Move Discrete -> Air )
