Science Projects [Magnets]

All materials here were produced while working for the Superconducting Magnets Group at Lawrence Berkeley National Laboratory during summer 2005 (Dipole) and summer 2006 (Quadrupole). My mentors in 2005 were Shlomo Caspi, Steven Gourlay, and Gary Ritchie. My partner for the 2005 project was another student named Michael Fuery, who recently graduated from UC San Diego with a concentration in Organic Chemistry and Biophysics. In 2006 I worked more closely with Shlomo Caspi and Gary Ritchie to develop the quadrupole version of the 2005 project.

Prototyping a Pure Cosθ Superconducting Dipole Magnet (PDF 714.7 KB)
This is a paper Michael Fuery and I authored for submission to the U.S. Department of Energy Journal of Undergraduate Research (JUR) discussing our Dipole Project. The abstract from this paper was published in JUR Vol. VI, 2006 (See "Student Abstracts").

Poster: Designing and Testing of the Dipole Magnet (PDF 213.2 KB)
This poster provides a conceptual undestanding of the coil geometry and the resultant field, and gives the results of our simulation for this dipole field as well as the physical measurements we made of the field during testing. We found that our model of the field was accurate to within 5% of the measured dipole field at the center of the magnet--1.02 tesla (with a 267 Ampere current applied).

Poster: Fabrication Procedure for the Dipole Magnet (PDF 217.7 KB)
This poster explains the procedure we used for building the dipole magnet. Gary Ritchie's technical knowledge and craftsmanship was heavily relied upon for the construction of the magnet.

Winding was a delicate process. With the winding table, a motorized tensioner that kept the NbTi wire taut, and our guiding hands, we had to make sure that as we wound the magnet none of the tension in the wire was lost.
