Duties include operation and maintenance of the target system including all the subsystems, cryogenics, and optimization of polarization while the experiment is running. The target experts are responsible for keeping the target system up and running and making repairs as fast as possible when the system is not up and running. Also, the target experts are responsible for taking calibration measurements of the polarization and making online assessments of the quality of the polarization calibration. The experts must be prepared to serve as a local experts and will be on-call 24 hrs/day 7 days week. Each target expert alternates as the leader Target Expert and contact a while being responsible for the full system with the help of the SpinQuest polarized target group. To serve as target expert you must be proficient in operating the cryogenic system, superconducting magnet, microwaves, and NMR. You must be able to load the insert with target material and load the insert in and out of the fridge safely. You must also know how to leak check with snoop and how to use a vacuum leak checker. There is an important distinction between a Target Expert and a Target Trainee; a Target Expert is expected to have the target system be their primary responsibility so they should always be available to the target effort even outside of the Target Expert shift.
Requirements: Resident at Fermilab during service as local target expert. Polarized target training on the above mentioned systems is required (See D. Keller). Knowledge of LabView and slow controls will be useful. Understanding the operation of oscilloscopes, RF electronics, and cryogenics is necessary.
