Low temperature research has become fairly widespread in the country after the availability of closed cycle refrigerators. It is opportune to write a book for students and researchers in India on production of low temperatures and techniques for the measurement of physical properties of materials at such temperatures. This book is an effort in this direction. The first part of the book discusses methods for producing temperatures down to 1.8 K. There is a fairly extensive discussion on different types of closed cycle refrigerators. The behaviour of properties of materials relevant in Cryogenics is dealt with in some detail. Useful tips on construction of cryostats are given. Thermometry is discussed extensively. The second part of the book deals with digital measuring techniques. Details of experimental methods for measuring thermal and electrical properties, point contact tunneling, scanning probe microscopy, and noise at low temperatures are discussed. This part of the book is born out of the rich personal experience in such measurements of one of the authors (AKR). There is an appendix on vacuum techniques. The book can be used for teaching an elective course in Low Temperature Physics at the M.Sc. level. It will be useful for researchers in Low Temperature Physics.

Measurements have been made of the specific heat at constant volume of solid He-3 from 3 K up to the melting point at a number of different densities corresponding to pressures up to 2000 atm. The measurements have been extended through the melting region at constant volume up to 29 K in the fluid phase. For comparison similar measurements have been made on He-4 at four different densities. By combining these data with the p-V-T data of Mills + Grilly (1955) and Grilly + Mills (1959), the complete thermodynamic properties of the solids have been derived in the relevant pressure and temperature range. The results can be understood semi-quantitatively in terms of the zero-point energy of the solids and a quasi-harmonic model of the lattice vibrations. A brief discussion of the specific heat of the fluid phase is also given. (Author).

The Helium Privatization Act of 1996 (P.L. 104-273) directs the Department of the Interior to begin liquidating the U.S. Federal Helium Reserve by 2005 in a manner consistent with "minimum market disruption" and at a price given by a formula specified in the act. It also mandates that the Department of the Interior "enter into appropriate arrangements with the National Academy of Sciences to study and report on whether such disposal of helium reserves will have a substantial adverse effect on U.S. scientific, technical, biomedical, or national security interests." This report is the product of that mandate. To provide context, the committee has examined the helium market and the helium industry as a whole to determine how helium users would be affected under various scenarios for selling the reserve within the act's constraints. The Federal Helium Reserve, the Bush Dome reservoir, and the Cliffside facility are mentioned throughout this report. It is important to recognize that they are distinct entities. The Federal Helium Reserve is federally owned crude helium gas that currently resides in the Bush Dome reservoir. The Cliffside facility includes the storage facility on the Bush Dome reservoir and the associated buildings pipeline.
