题目: Physics and Engineering behind the Thermometry and Conductive Heat Transfer at ULT
时间: 2014年11月27日 09:00
地点: 中科院物理所M楼253室
报告人: Dr. Zuyu Zhao

Abstract:

Ultra-low Temperature (ULT) Technologies has been developed shoulder to shoulder with helium physics research (where the ULT Physics research originally started), and they have found themselves with much broader applications in Frontier Physics research nowadays such as ULT-STM systems in high magnetic fields, Angle-resolved photoelectron spectroscopy (ARPES) below 1K, Cosmology Physics, Atomic Physics, Dark matter search, Quantum computing, Atomic Physics, Superconductivity Physics, etc.
This seminar includes two parts and they will focus on two of the most important ULT technologies: ULT thermometry and thermal conduction at ultra-low temperatures.
I. Part-I will introduce various types of cryogenic thermometers, including both primary thermometers and secondary ones, and we will compare their advantages and disadvantages.
II.Conductive heart transfer has become challenging at ultra-low temperature, and part-II will cover discussions on cases of both hard contact and flexible thermal link.

Speaker:

Dr. Zuyu Zhao received his B.S. degree from Fudan University in 1982, Class 77.He came to US in 1983 with the World Bank Scholarship and graduated from Northwestern University with Ph.D. degree of physics in 1990. He then spent two and half year working at Harvard University as post-doc and set a new lab pursuing Bose-Einstein condensation on spin polarized hydrogen.
Dr. Zhao joined Janis Research Company in 1993 and focused on developing custom ultra-low temperature facilities for the research and science community.
He is currently the Board of Director and Vice-President-Principal scientist of the company.At the same time, he has been elected as member of the AIP <<Physics Today>> Advisory Committee Member from 7/1/2007 to 6/30/2013.
