Ultrasonic Equipment for Undergraduate Projects and Research

该设备将继续发展超声波 米勒斯维尔大学物理系的实验室。 非常高频率的声音脉冲被用作探针（类似于 SONAR）研究基础物理学（高温的性质 超导体），生物物理学（血红蛋白和酶的性质）， 以及波的性质（相位和群速度、反射 系数，布拉格散射的光由声音，傅立叶 脉冲调制波测不准原理 关系）。 这些研究可以在工作台上以低成本进行， 很容易被本科生理解。 他们提供物理学 专业满足他们所需的高级研究要求， 进入研究，这总是有趣的，偶尔 易腐烂的。 仪器是不吓人的，和过程中， 产生和检测声音是直观可及的。 该奖项 我将购买两个插入式电子模块，以覆盖频率 范围为10至90 MHz和90至300 MHz。 该机构将提供一个 金额相当于项目成本奖励的135%。

The equipment will continue the development of the ultrasonics laboratory in the Physics Department at Millersville University. Pulses of very high frequency sound are used as a probe (analogous to SONAR) to study fundamental physics (the nature of high temperature superconductors), biophysics (properties of hemoglobin and of enzymes), and the nature of waves (phase and group velocity, reflection coefficients, Bragg scattering of light by sound, the Fourier uncertainty principle for pulse modulated waves, the Kramers-Kronig relation). These studies can be done on a bench top, at low cost, and are readily understood by undergraduate students. They provide physics majors fulfilling their required senior research requirement with an entry into research which is always interesting, and occasionally publishable. The instrumentation is unintimidating, and the process of generating and detecting sound is intuitively accessible. The award will purchase two plug-in electronics modules to cover the frequency ranges 10 to 90 MHz and 90 to 300 MHz. The institution will provide an amount equal to 135% of the award toward the cost of the project.
