Activity 1: Target preparation and characterization

Powell Barber, Sergio Almaraz-Calderon

Location: Collins Laboratory, Room 51

The students will have the opportunity to participate in almost all aspects of the production of thin carbon foils by carbon arc evaporation, to include substrate cleaning and preparation, evaporation, as well as film removal and mounting.  Target production techniques for other materials will be discussed based on student interest and available time. A review article on different techniques is available at http://iopscience.iop.org/0022-3735/12/9/001/

The students will also determine target thicknesses by measuring the energy loss of alpha particles as they pass through a target foil. Students can download the LISE-program to perform the relevant energy-loss calculation.

 

Activity 2: Measurement of the 12C(d,p)13C reaction at the FSU accelerator

Kirby Kemper and Lagy T. Baby

Location: Collins Laboratory, Rooms 7 and 10

The students will perform an experiment at the Tandem-accelerator. The Tandem will produce a beam of Deuterons at 12 MeV, which will be transported and focused onto a 12C target located in the center of a scattering chamber. The students will create a beam focus on the target location by adjusting a Quadrupole-double lens and several steerer magnets. Once the beam is focussed and optimized, the target will be inserted and the experiment begins. The experimental setup contains a thin-thick Silicon “telescope”, which is movable around the target and will be used to measure the energy spectra and  angular distributions of the deuterons and protons emerging from the target, produced in the elastic scattering and (d,p) transfer reaction, respectively. The particle energy-spectra will be recorded in short runs for every angle. Another Silicon-detector will remain at a constant angle, monitoring the integrated beam intensity by detecting elastic scattering for every angle-run. The different final states populated in the (d,p) transfer reaction will be identified and their angular distribution will be analyzed.

Activity 3: Analysis of transfer reactions, DWBA and shell-model calculations

Jessica Baker and Sean Kuvin

Location: Collins Laboratory, Room 13

The students will develop a DWBA calculation of the 12C + d  elastic scattering and the 12C(d,p)13C reaction using the program DWUCK. The elastic scattering data from the experiment will be used to adjust the optical potential parameters user in the DWBA calculation and to obtain an absolute cross-section  normalization of the experimental data set. The DWBA description of the transfer-reaction will be used to extract spectroscopic factors for the observed states in 13C.

In a second part, the students will perform a shell-model calculation to compare the experimental spectroscopic factors to theory and better understand their implication. More detailed instruction and the computer-codes needed for the calculation (Linux and Mac) are available at
http://www.volya.net/index.php?id=ebss2015. Students can use their own, or laboratory-computers to perform these calculations.

Activity 4: Analysis of high-resolution Gamma-spectra from Beta-decay

Vandana Tripathi, S.L. Tabor, Rutger Dungan, and John Parker

Location: Collins Laboratory, Room 214,215

In this activity the students will learn about two of the three nuclear decay modes identified by the “father” of nuclear physics, Ernest Rutherford, namely beta and gamma decay. Beta decay has a distinguished history revealing the first elusive particle, the neutrino, the 14C dating technique, and has been extensively used for studying nuclear structure. It is also very much a part of the future in the study of rare isotopes at radioactive beam facilities like NSCL, TRIUMF, GSI, GANIL, CERN, and RIKEN.   Gamma spectroscopy with high resolution (~2 keV) detectors is the most important tool to study properties of excited nuclei and to determine decay schemes and exploring nuclei with respect to nuclear models.  

In this project you will measure the electromagnetic radiation (γ rays) following  β decay.  The β-  decaying samples were prepared by nuclear reactions on stable isotopes using our accelerator facility.  Their lifetimes are long enough so that most of the radioactive material has survived for your experiment.  β decay often leaves the daughter nucleus in excited states which then decay by γ emission allowing us to study the excited states of the daughter nucleus.

Two high-purity Ge diode γ detectors, connected to a digital data acquisition system, will be used in this exercise.  You will first calibrate the energy response of these detectors using a β-γ source (152Eu) with known γ energies.  The main project will be to measure and analyze the γ-γ coincidences from the pair of Ge detectors to determine the gamma transitions and hence energy levels in the daughter nucleus following the decay of the sample.

 

Activity 5: Methods of neutron detection

C.J. “Kim” Lister (University of Massachusetts Lowell) and Nabin Rijal

Location: UPL 110  

Neutrons are a key to the nuclear science of stars, reactors and bombs. They are also critically important in the nuclear structure of neutron-rich isotopes. They were not discovered until 1932 and still remain difficult to detect and measure. They are radioactive, and so free neutrons are absent from our environment, unless some nuclear process is present.

As neutrons are electrically neutral they can only be detected indirectly, either following scattering or absorption. The big experimental problem is that the signal generated by neutron interactions is often difficult to separate from that caused by gamma rays.

In this laboratory we will discuss how the detection of neutrons in scintillating materials works. We will have three “hands on” projects and some short talks about new “state of the art” techniques, like using traps to infer neutron decay, and the new scintillator CLYC.
