Professor Oscar Vilches, who heads the lab, is shown here beside the cryocooler.

Roberto Ramos is in his last year of phd studies at UW and has been with the Low Temperature Lab for under 3 years, measuring heat capacities of monolayer films of 3He and mixtures of 3He-4He atoms using a dilution refrigerator configured to go down to 0.1 Kelvin. He is currently examining liquid-vapor condensation of 3He-4He mixtures and also searching for single layer phase separation for his dissertation.

After working as an undergraduate student in the lab, Tate Wilson is now the newest graduate student in the group and is using AC Calorimetry to look at hydrogen-deuterium monolayer films. He has been constructing various graphite cells and optimizing signal/noise ratios to measure small heat capacities.

Stuart Hagler is a Masters student currently working with Tate Wilson on the development of small sample calorimetry.

Bernd Sing, a graduate student from Germany has been continuing the ongoing project on frost heave in argon. Early this fall, he was successful at observing frost heave in argon using the new cell design he is holding in this picture

Adam Tyburski is a junior undergraduate student who is currently performing developmental work with a CTI Cryocooler for studies of superconducting transitions in a mercury film.

Kristen Russell, a visiting 1999 REU student from Louisiana, is shown here adjusting the frost heave cell during a recent run.

Professor Da-ming Zhu was a 1998 visiting professor, on Sabbatical leave from the University of Missouri-Kansas City. He is shown here setting up a frost heave experiment.

Jeff Friesen, a former undergraduate senior, has moved on as a graduate student at the University of Colorado in Denver. He was engaged for a while in developmental work, coating a quartz crystal microbalance with graphite and adsorbing helium on it.

Johannes Ulrici, a visiting 1998 graduate student from Germany and a Fulbright scholar here in the US, has returned to Germany. He had been performing computer simulations mapping out potentials in glass-forming systems and here shown helping with the experiment on frost heave.

Ben Stottrup, a visiting 1998 REU student from University of Minnesota at Morris, is shown building the prototype of the frost heave experiment apparatus. He has chosen to join the U of Washington Physics Dept as a graduate student in Fall 1999.
