A Personal Statement

It has been a privilege to receive opportunities to work and contribute to both the conventional superconducting magnet designs and technologies and to the new magnet designs and technologies.

I worked on the conventional cosine theta magnet designs based on the NbTi superconductor for the Superconducting Supercollider (SSC), and the Relativistic Heavy Ion Collider (RHIC) to develop and demonstrate:

Seeing that work used in the magnets of a major accelerator (RHIC at BNL) was a truly fulfilling experience. I gave several talks, wrote papers, and gave courses so that these techniques can be used in future accelerators, such as VLHC, FCC or LHC at CERN, SppC.   

After the completion of RHIC, I moved on to developing and demonstrating new magnet designs such as:

I also helped develop and demonstrate new and developing magnet technologies such as:

Often these new and vastly different technologies than those ever used before require a fresh look at the basic magnet design from the first principle. In fact, this led to the development of the new and innovative magnet designs mentioned above.

 I further realized that we also need to change how we do the magnet R&D. Conventional way of doing R&D takes too long and is too expensive. Getting a positive outcome then becomes too important. Therefore, to assure success one tends to incorporate many improvements (changes) at one time into a single magnet. This in turn makes it difficult to identify what individual change made the improvement or what was responsible for the poorer performance. I saw a need for and developed new ways of doing magnet R&D which are lower-cost and have rapid-turn-around. They encourage both:

For example, an insert coil in BNL common coil dipole DCC017 becomes an integral part of the magnet in the highest field area and an insert coil test becomes a low-cost, rapid-turn-around magnet test.

If a test result is positive, it becomes a demonstration of the new design or new technology and can be used more confidently in a new magnet. However, if a test result comes out to be negative, the test result need not be seen as a failure of that magnet project. It could and should be seen as a low cost insert coil test where we tried something that didn’t work.

Though everything must be done to avoid or minimize a negative outcome, being prepared for occasional negative results must be a part of learning and innovating.  Experimental results help us understand what works and what does not. We need to find out why, and what was the cause of the negative outcomes. Then, we make corrections, or find alternate solutions, and move ahead. In fact, both negative and positive test results are an integral part of developing new designs and/or technologies optimally.
