He-Ne laser
This experiment explores the polarization, spatial and temporal coherence
of the output of a He-Ne laser, as well as the basic conditions for laser
action.
Magnetization and tranzition temperatures of
superconductors
This experiment measures the magnetization of type I and type II
superconductors as a function of temperature and magnetic field.
Scanning Tunneling Microscope
Various surfaces are studied with the STM, up to atomic resolution.
Several samples are available to dtudy a variety of surface science
effects. Quantum tunneling is at the hearth of this device and can be
verified experimentaly.
Semiconductor resistance, band gap and Hall
effect
This experiment studies the properties of n and p type semiconductors.
Among the measurable quantities are the mobilities, Hall coefficients,
and their temperature dependencies.
Neutron diffusion in H2O
Neutron thermalization and diffusion in water can be studied by
irradiating indium foils at various distances from a point source in a
large water bath. The results can be fitted to a "two-group" theory formula.
Measurement of the Compton total cross section
Measurements are made to study the total cross section(s) for Compton
scattering of gamma-reys by materials of various values of Z.
Mass spectrometer
Although usually thought as a device for measuring isotopic abundances,
here the mass spedtrometer is used to study the appearance potential and
ionization cross section for electrons incident on inert gasses.
Gamma ray spectroscopy with a germanium
detector
The use and calibration of hyperpure germanium crystals as solid state
ionization chambers are studied. Gamma ray spectra are very accurately
analyzed at high resolution. A variety of measurements are possible.
High energy physics
Photographs of 10 GeV bubble chamber events are studied in which strange
particle creation and decay are evident. Careful measurement of vector
momentum makes it possible to set upper limits on the unobservable
missing tracks.
Muon lifetime
Several cosmic ray muons stopped each minute in a large volume
scintillator. By studying the spectrum of time delays between muon entry
into the scintillator and muon decay, the half life can be measured.
Slowpoke nuclear reactor - kinetic behaviour
Response of the Slowpoke nuclear reactor is studied as the control rod
positions are varied.
