Procedure to install/change solid targets
Experts: Matt Marchlik, Alexandre Deur, Tim Withlatch
Procedure:
- If needed, request Radiological survey of the target area.
- Remove the beam profiler if necessary.
- Open the two hose clamps holding the beam tube to the fixed V-blocks, see 1st picture.
- Spin the jack adjustment nut on the adjustable V-block rest until the beam line is high enough to allow the target mount tube to be easily removed. See the jack on the 2nd picture
- Remove the target mount tube. Make sure you support it horizontally to not break the thin white extremity of the tube (fragile) , see 3rd photo showing the white extremity:
- Remove the current target and replace it with the desired one. The targets are stored in a yellow plastic bin attached to one of the beam line post.
- Insert the target mount tube. Make sure you support it horizontally to not break the thin white extremity of the tube (fragile). Slide it up to the nominal target Z-position marked by a white ring painted on the target tube.
8.) Lower the beam line down onto the two fixed V-blocks by spinning the adjustment nut on the adjustable V-block rest. Spin the nut a couple of times further to ensure the temporary V-block is not in contact with the beam line. 9.) If necessary, Reinstall the profiler. 10.) Update database to reflect the target change: procedure to update the target status in the database.
