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.
