Dear Dave,

I would like to nominate Dr. Xiaobiao Huang's thesis for the competiton of the DPB outstanding thesis competition. Dr. Huang came to IU in 2001. He passed the qualify exam in 2002 with distinction. He joined the accelerator physics in the summer of 2002.

During the 2002-2003, he has worked with my group on half integer stopband correction, orbit response matrix analysis for PSR. After many discussions with our colleagues on the NEED of proton flux in the Fermilab Booster, I convinced Dr. Eric Prebys on the important of having a graduate student working on this project. In March 2003, he began working at the Fermilab Booster for his Ph.D. thesis.

During the course, he has worked on method to alleviate the problem of the injection and extraction DOG-LEG problems at the Booster.
In the summer of 2003, he began to introduce the independent component analysis method into the beam physics mass data mining. Because of his efforts, the Fermilab Booster has for the first time successfully modeled and accelerator properties systematically measured. He has nominated to presnt an oral talk at the PAC05. The details of theis method have been documented in his Ph.D. thesis. Besides the introduction of the ICA method into beam physics, he has systematically carried out emittance evolution measurements at the Fermilab Booster as a function of the beam intensity.
These measurments will be important to understand the emittance growth mechanism.

Although the power of ICA method has yet to be fully explored, Dr. Huang has used the ICA method to measure chromaticities and impedance during the ramp. Dr. Huang is dilligent and innovative. I am sure that he will make more contribution to beam physics. I do beleive that his thesis qualify for the competition of the outstanding Ph.D. thesis in DPB.
Your consideration will be highly appreciated.
Supporting letters will be submitted to you very shortly by colleagues who have work with Dr. Xiaobiao Huang.

Yours Sincerely
