Revision as of 17:52, 17 February 2011
Objectives
1.) Check alignment of the OTR target and beam line with the linac's central axis. If it is misaligned we will work on an alignment plan to be executed after the Wednesday beam test.
2.) Take OTR images, check image focus and light output.
3.) Determine which quad to use for emittance measurements. Establish a quad current scan range.
Steps
Practise Turning HRRL On
Make document of the whole process, write a Standard Operation Process (SOP).
Turn RF off, Try to see Image with filament on
If we can see filament spot on the OTR target, try to focus our image system.
Turn RF On
Turn RF on look at the images, take pictures of the image upload them to the wiki.
Experiment
First Fusing
Image on OTR target
| Lights | RF | image |
| on | off | 
|
| on (different contrast) | off | 
|
| off | off | 
|
| on | on (27 Hz) | 
|
RF:25-205, Peak Current50mA, Pulse Width_200ns (fwhm)
RF:25, Peak Current60mA, Pulse Width_200ns (fwhm)
RF:50
Second Fusing
Focused With Lenses,140 mA 58Hz 100ns
Determine the smallest energy, beam current, pulse width, and rep rate for a visible image.
