1. The PHENIX (Pioneering High Energy Nuclear Interaction eXperiment) experiment at the Relativistic Heavy Ion Collider (RHIC) on Brookhaven National Laboratory (BNL).
a. Primary goals of the PHENIX experiment include understanding the internal structure of the proton and investigating the nature of quarks and gluons.
b. Involved 12 different ACU students in the past 3 years.
c. This summer 5 students will work at BNL with Dr. Towell.
d. One student will work on PHENIX data analysis with Dr. Daugherity at ACU.
2. The E906 experiment at Fermi National Accelerator Laboratory (FNAL).
a. The primary goal of E906 is to study the anti-quark content of the proton.
b. Eight different ACU students have worked on this experiment over the past 3 years.
c. This summer 5 students will work at FNAL with Dr. Isenhower.
3. The NIFFTE (Neutron Induced Fission Fragment Tracking Experiment) experiment at Los Alamos National Laboratory (LANL).
a. The primary goal of the NIFFTE collaboration is to carefully study neutron induced fission. These measurements are vital to the design of the next generation of nuclear power plants.
b. This experiment will help provide a clean, abundant, and safe energy source for our future.
c. Six different ACU students have worked on this experiment during the past year.
d. This summer three students will work at LANL.
e. Dr. Qu and Mr. Watson will also work on this project at ACU.
The Solid State Research Group
Faculty member: Dr. Timothy Head, assistant professor
External support: Equipment totaling over $120,000 has been given to this group from the University of Illinois at Urban-Champaign.
1. Measurement of acoustic properties of CaWO4 using the phonon-imaging technique. This project is being done in collaboration with Madeleine Msall of Bowdoin College and Jim Wolfe of the University of Illinois Urbana-Champaign.
a. The goal of this research is to provide a more precise set of elastic constants for CaWO4 to researchers in the CRESST collaboration. These values will be used to better characterize their detectors as they search for the dark matter that holds our galaxy together
b. Three students have been involved in this work at different times beginning in summer of 2008.
2. Phonon-imaging study of superconducting Tin.
a. The primary goal of this project is to investigate the cause of long thermalization times observed in superconducting Tin using the phonon-imaging technique. This research has application in the fast detection of gamma rays in a new type of gamma ray spectrometer that uses superconducting Tin to stop the gamma rays.
b. One student is set to begin work on this project in summer 2009.
Quantum Gravity Research
Faculty member: Dr. Joshua Willis, assistant professor
External support: Dr. Willis has been supported by funds from a National Science Foundation grant.
Current project: Dr. Willis studies how the force that holds the universe together on the largest scales (gravity) can be understood with the same principles that describe physical systems at the smallest scales (quantum theory). Some of this work is theoretical modeling, and much is computational. There is research done on both how to get computers to more efficiently make the calculations we need, as well as using large computer calculations to extract predictions from theories.
Relationship between Philosophy, Science, and Religion
Faculty member: Dr. Paul Morris, Professor
Research support: Dr. Morris will be on sabbatical next school year.
Current project: The Historical Impact of Mathematics on Philosophical Thought in the West.
Partial Wave Analysis of the Pion-Nucleon System
Current faculty member: Dr. Michael Sadler, Professor
Research support: Dr. Sadler is on sabbatical this school year.
Current project: Organizer of the 5th International Pion-Nucleon Partial Wave Analysis Workshop in Trento, Italy.
