The position requires expertise in all polarized target subsystems including:
- Liquid Helium and Liquid Nitrogen Cryogenics
- Operation of evaporation refrigerator
- Superconducting magnet
- Microwave system
- NMR and polarization measurements
- Target material handling and loading
Duties include operation
...
any 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
...
the local experts and target contact and will be on-call 24 hrs/day 7 days week. Each target expert alternates as the lead Target Expert and contact while being responsible for the full system, target polarization runs, and activities planning with the help of the SpinQuest polarized target group. You must know how to take a high quality thermal equilibrium measurement to calibrate the NMR measurements. 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 to find leaks and determine if something is helium tight. You are responsible for coordinating and planning the target aspects of the calibration/production activities with the Run Coordinator.
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. To serve as Target Expert you will be assigned an ongoing target related project and expected to report on progress regularly.
