Physics and Astronomy Facilities
Departmental facilities are located in the Hoffberger Science Building (HS). We make no distinction between teaching and research facilities; students are encouraged to use the equipment for faculty/student collaborative research and independent study projects, as well as to utilize the equipment to conduct regular laboratory experiments.
Machine Shop-Hoffberger Science Building, HS-B21
The department has established a workable small size machine shop for the support of research and teaching laboratories, the departmental observatory, and student-faculty projects. The machine shop has a medium-size milling machine, a small lathe, a vertical band saw, and a vertical drill.
Atomic Force Microscope Laboratory, HS-B31
Atomic Force Microscope (AFM) is used by the Chemistry and the Physics/Astronomy departments for student/faculty collaborative research projects in materials science, surface science, physical science, and biochemistry. Purchase of the AFM system was made possible by the funding from the National Science Foundation (NSF-DUE-CCLI grant # 0088172, P. I.'s Dr. Scott Sibley and Dr. Sasha Dukan). Goucher College Innovation Grant funding enabled the P.I.'s to obtain the LiquiScanTM upgrade that gave the departments ability to study nanostructures and biomolecules.
Interactive Lecture/laboratory Room One, HS-B26
Interactive lecture/laboratory room one is equipped with six sets of the latest version of the PASCO interface boxes and all the digital and analog sensors that are pertinent to the PASCO system. The sensors are used for data acquisition in a series of 28 experiments that are related to kinematics and dynamics of linear, circular and angular motions, conservation of energy and momentum, oscillatory and wave motions, electricity and magnetism, and geometric and physical optics. Room layout facilitates innovative workshop-type physics instructions where lectures and laboratories are combined and learning is fostered through various hands-on activities
Interactive Lecture/Laboratory Room Two, HS-B27
Interactive lecture/laboratory room two is equipped with six sets of the latest version of the PASCO interface boxes and all the digital and analog sensors that are pertinent to the PASCO system. The sensors are used for data acquisition in a series of 28 experiments that are related to kinematics and dynamics of the linear, circular and angular motions, conservation of energy and momentum, oscillatory and wave motions, electricity and magnetism, and geometric and physical optics. Room layout facilitates innovative workshop-type physics instructions where lectures and laboratories are combined and learning is fostered through various hands-on activities
Materials Physics Research Laboratory, HS-G29
The materials physics research laboratory includes instrumentations for sample preparations such as Glove box, Hood, Spex-8000 Mills, High Temperature Tube Furnace. Additional sample characteristic measurements are carried out via computerized temperature acquisition system in this lab as well as by using AFM and XRD in different locations.
Atomic/Molecular and Optics Laboratory
The AMO lab includes experimental setup for cooling and trapping cesium and potassium atoms and production of ultracold molecules through photoassociation. Two external cavity diode lasers are used for Cs trap while the K trap uses one master laser and a tapered laser amplifier. Saturated absorption setups are used for active laser stabilization (<250 kHz). The traps are obtained in SS UHV chamber equipped with florescence and ion detection. Additional diode lasers at 850, 457 and 405 nm ECDL or free running are used for photo association. A pulsed nitrogen dye laser can be used for resonant photo-ionization detection.
Theoretical/Computational Condensed Matter Physics Research Laboratory, HS G10-A
Theoretical/Computational Condensed Matter Physics Research Laboratory houses a cluster consisting of the two Dell Precision 380n workstations (named DJANGO and SIMONE) with the Scientific Linux operating system as well as the newest member Mac Pro Quad (named ELLA). Most of the software installed on the cluster is license-free and includes FORTRAN, C and C++ compilers, various graphing and data processing utilities. Cluster is equipped with the licensed Maple and IDL software packages.
Computational Astronomy Research Laboratory-G10A
The Computational Astronomy-Research Laboratory consists of three dual-processor iMacs and a 16-processor PowerMac configured to run as a small parallel-processor supercomputer. This setup allows up to three students to participate in student/faculty collaborative research on both observational-astronomy projects (using ground-based, Hubble, and Spitzer data) and numerical simulations of the interaction of radiation, gas and dust using Monte-Carlo radiative-transfer simulations. These facilities were made possible with grants from the Space Telescope Science Institute and the Spitzer Science Center.
Intermediate Physics Laboratory, HS G10-B
Intermediate Physics Laboratory currently houses setups for twelve experiments : electron e/m ratio experiment, measurement of speed of light , Millikan oil drop experiment, Frank-Hertz experiment, photoelectric effect experiment, black body radiation experiment, Hall effect, Davisson-Germer experiment, muon lifetime experiment, two-slit one photon at a time experiment, atomic spectroscopy and radioactivity experiment. In a given semester up to ten experimental projects are carried out by students.
Electronics/Instrumentation Laboratory, HS G10-B
Electronics and Instrumentation experimental course is taught through interactive hands-on approach. The space for this lecture/lab course has five stations for designing, constructing, and testing electronics circuits and setups. Each station is equipped with a function generator, a digital oscilloscope, power supplies, prototype boards, and laptop computer with a USB data acquisition module and LabVIEW environment. In addition, the lab has a large collection of analog and digital electronic components and supplies.
The roof of the Hoffberger Science Building houses the Lewis Astronomical Observatory, a generously-sized telescope dome inside of which is our permanently-mounted 14-inch Schmidt-Cassegrain telescope. This telescope is equipped with a computer and GPS- controlled German-equatorial mount, as well as a 3-inch triplet refractor for wide-field imaging. Either telescope can be outfitted with our full-color Starlight Xpress SXVF-M7C 752 x 580 pixel CCD camera for deep-sky imaging. The dome also houses three portable 6-in Celestron Schmidt-Cassegrain telescopes with full computer control for classroom and public-outreach use. The observatory serves the Introductory Astronomy (AST 110) courses, as well as provides monthly public observing nights throughout the semester.
Mounted on top of the Hoffberger Science Building is our CASSI small-radio telescope, which has been used in the past in student/faculty collaborative research to measure the rotation curve of our galaxy or the radio brightness of the sun.
