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

- 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" -> TARGET_tertiary Air -> Move Discrete -> "Pb_lead (6mm)")

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

- 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" -> 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 )
Load Magnets
