Novel horn designs for power ultrasonics
Aug 24, 2004
Sherrit, Stewart; Badescu, M.; Bao, X.; Bar-Cohen, Y.; Chang, Z., 2004, "Novel horn designs for power ultrasonics", https://hdl.handle.net/2014/41503, IEEE Symposium on Ultrasounics, Montreal, Canada, August 24-27, 2004., JPL Open Repository
Ultrasonic horns are used in a variety of industrial and medical applications. At JPL a rock-sampling tool based on an ultrasonic horn was developed to drill, abrade and core rock samples including hard basalts. This device is an impact device, which uses ultrasonic vjbratlons th...

Subsurface ice and brine sampling using an ultrasonic/sonic gopher for life detection and characterization in the McMurdo Dry Valleys
Mar 1, 2004
Bar-Cohen, Y.; Sherrit, S.; Chang, Z.; Wessel, L.; Bao, X.; Doran, P. T.; Fritsen, C. H.; Kenig, F.; McKay, C. P.; Murray, A.; Peterson, T., 2004, "Subsurface ice and brine sampling using an ultrasonic/sonic gopher for life detection and characterization in the McMurdo Dry Valleys", https://hdl.handle.net/2014/38140, SPIE Smart Structures Symposium, San Diego, CA, March 15, 2004, JPL Open Repository
There is growing evidence for ice and fluids near the surface of Mars with potential discharge of brines, which may preserve a record of past life on the planet. Proven techniques to sample Mars subsurface will be critical for future NASA astrobiology missions that will search fo...
