  *iPVarray (University of Queensland, Australia)
  An instrumented PV array of 12 x 60W solar panels at the University of Queensland. This 720W array is connected to the grid with a Fronius grid connect inverter. Each individual solar panel is instrumented via a network of data logging / power electronic converter boards so that each solar panel’s voltage, current and temperature can be logged.
  
  

Control Experiments

• Inverted pendulum (University of Queensland, Australia)
  Inverted Pendulum is a well known control theory experiment where by control laws are derived and tweaked as to balance a pole much like one balances a broom on their finger.
  
  
• Power Flow Control Generators (RMIT University)
  The variable frequency inverter fed Induction Motor is driving the Generator. Induction motor represents the Turbine in real life situations. The generator is loaded. Induction motor is driven by V/F inverter. This controls the torque provided on the generator shaft. With increasing torque the real power generated goes up. When the field voltage is increased the reactive power generated by the generator goes up but not the real power delivered.

Spectrometer Experiments

• Neutron Beam (MIT)
  Demonstration of Half Thickness or Shielding Effectiveness in a Neutron Beam. The objective of this experiment is to demonstrate thermal neutron behavior in the presence of various absorption materials. The experiment utilizes a 4" beamport which provides a continuous beam of low-energy neutrons that is controlled using a mechanical chopper. Students are asked to calculate neutron flux and neutron density using the data gathered from the neutron detectors. Then, the students are asked to position standard pieces of lead, boron, cadmium, and aluminum prior to the neutron detectors in the beam guide tube. They perform another round of measurements. Based on the data collected, students are asked to calculate the half-thickness (or shielding effectiveness) of various materials.
  
  
• Maxwell Boltzmann Distribution (MIT)
  Measurement of the Maxwell Boltzmann Distribution of Thermal Neutrons from the MIT Research Reactor (MITR). The objective of this experiment is to correlate the by correlating the temperature of the reactor with the availability of thermal neutrons for measurement, and then to compare the results with the Maxwell Boltzmann distribution that is predicted. The experiment utilizes a 4" beamport which provides a continuous beam of low-energy neutrons that is controlled using a mechanical chopper. Students are asked to perform measurements at two points in the beam guide tube using neutron detectors, multi-channel analyzers, and oscilloscopes. Students plot the data they gather and attempt to calculate thermal neutron velocity and flux density.
  
  
• Bragg Diffraction and the DeBroglie Wavelength (MIT)
  Demonstration of Bragg Diffraction and the DeBroglie Wavelength . The objective of this experiment is to demonstrate neutron diffraction using a crystal monochromater. The experiment utilizes a 4" beamport which provides a continuous beam of low-energy neutrons that is controlled using a mechanical chopper. Students are asked to measure the Bragg-diffracted beam that is created by altering the neutron beam path with a copper crystal. They perform several measurements at various angles of incidence, and are asked to plot their data to demonstrate the DeBroglie relation.
