Target Requirements Target Requirements

Generate a one cm. diameter arcing horizontal jet of mercury to provide a 10 to 15 cm interaction length with the proton beam. Provide an unobstructed view of the interaction zone for high speed imaging. Operate simply, reliably and remotely. Safely contain projectiles which may be generated by mercury-beam interactions Manage mercury vapor generation Mounting system to provide for easy interchange of other test targets Materials of construction must be compatible with mercury and survive a radiation environment.

Conceptual Approach Conceptual Approach

Internal and external target containments:

Use commercial conflat vacuum components, blind-flange beam windows, quartz and/or Lexan view ports wherever possible. Use standard instrumentation and pneumatic feedthroughs wherever possible.

Design approach:

design to reduce beam intensity on windows

• ptimize materials to insure survivability

insure mercury compatibility fiducial registration for target change out

Current Status Current Status

Water jet tests are essentially complete. Mercury jet target designs are substantially complete, minor detailing still underway. Test stand will be installed in beam line very soon. Materials list with prices and quotes about 75%

• complete. Ready to order many components

now. Next step is to prepare for the experiment safety review, then begin target construction.
