Postdoctoral position at Caltech in the Bellan Plasma Group

  • Recent Ph.D. degree in Experimental Plasma Physics or closely related field
  • Preferred experience: X-ray imaging techniques, coded aperture methods, general plasma diagnostics, pulsed power operation, fast data acquisition, measurement of low-level signals in an extremely noisy environment
  • Required knowledge: optics, imaging, X-ray spectroscopy, plasma physics, numerical techniques for data analysis, electronics, vacuum techniques
  • General: Excellent oral and written communication skills
    This position is to participate in construction, deployment, operation, and analysis of a new X-ray imaging diagnostic. A coded aperture imaging system for radiation that cannot be focused using conventional optical methods will be constructed and demonstrated to work with X-rays in the multi-kilovolt range. After testing at Caltech, this system will be fielded on pulsed, intermediate-density fusion experiments elsewhere. The spatial location of the X-ray source and possibly other forms of radiation (gamma rays) or energetic particles (neutrons) will be measured. This will be done in association with a graduate student who has already done significant initial work. Prototypes will be tested at Caltech before being used elsewhere.

Publications relating to previous work at Caltech on this are:

Coded aperture: Haw, Magnus A. and Bellan, Paul (2015) 1D fast coded aperture camera. Review of Scientific Instruments, 86 (4). Art. No. 043506.

X-ray detection: Marshall, R. S. and Flynn, M. J. and Bellan, P. M. (2018) Hard x-ray bursts observed in association with Rayleigh-Taylor instigated current disruption in a solar-relevant lab experiment. Physics of Plasmas, 25 (11). Art. No. 112101.

Appointment is for one year with extension to second year if performance satisfactory.

Applicants should submit the following:
1. Paragraph explaining interest in position and giving evidence of suitability
2. Resume
3. Names of three references

These items should be sent to Professor Paul M. Bellan: pbellan@caltech.edu
