abstract = {Ultrasonic systems are powerful tools to determine elastic
wave velocities of minerals and materials at high pressure
and temperature and have been extensively developed in
recent decades. However, accurate measurement of sample
length is required to convert travel times into wave
velocities, limiting their use to synchrotron facilities or
room temperature experiments in laboratories. We have made
use of a close collaboration between the Bayerisches
Geoinstiut and the P61B end-station beamline (PETRA III -
DESY) to install ultrasonic systems and develop a novel dual
travel time method for in situ pressure determination
without the need for synchrotron radiation. Our method
relies on the travel times of elastic waves through a
reference material; it requires a thermocouple and is
non-intrusive, with the reference material replacing the
backing plate of the high-pressure assembly. Pressures
obtained from this dual travel time method show excellent
agreement with those obtained from x-ray diffraction using
synchrotron radiation on standard materials. Our novel
method enables in situ pressure determination at varying
temperatures during in-house ultrasonic interferometry
experiments. This allows us not only to determine the
elastic behavior of minerals and materials but also to
investigate phase diagrams, solidus, or liquidus conditions
at varying pressures and temperatures during in-house
experiments. During the installation of the pulse-echo
ultrasonic system, we identified critical parameters for
obtaining reliable data. While these requirements are
well-known to experts, this study presents a comprehensive
review of the different characteristics of ultrasonic
systems, providing user-friendly guidelines for new users
installing and operating such systems in high-pressure and
high-temperature conditions.},
