Our experimental work is conducted at the
Triangle Universities Nuclear Laboratory (TUNL). TUNL is a
consortium of North Carolina State University, Duke, and the
University of North Carolina at Chapel Hill.
TUNL consists of three main accelerator facilities:
The Tandem Accelerator Lab
Powered by a 10 MV van de graff accelerator, this facility
delivers proton, helium, and deuterium beams with energies of up
to 40 MeV to a range of target areas.
The High Intensity γ-ray Source (HIγS)
The HIγS facility uses a free electron laser to
produce the most instense mono-energetic photon source in the
The Laboratory for Experimental Nuclear Astrophysics (LENA)
The LENA facilty is a dedicated nuclear astrophysics
laboratory aimed at employing world-leading detector
technology and the world's most intense proton beam to study
small cross sections.
The Enge Split-pole Spectrograph
The centerpiece of our experimental equipment is the Enge
Split-pole Spectrograph: a high resolution particle spectrometer
dedicated to nuclear astrophysics experiments. By using a
high-field magnet, particles are bent depending on their
momentum and detected at a focalplane. Features of the Enge
A high-precision focalplane detector with:
Two position-sensitive avalanche counters for
particle-by-particle ray reconstruction
A proportional counter for particle
A scintillator stopping detector to measure the final
energy of particles
Variable entrance windows for high-precision or
High resolution beam delivery. A series of feedback
circuits through two 90-degree magnets allow us to deliver
precise energies to a very small beam spot.
