Abstract

A focal plane detector for the Enge Split-pole Spectrograph at Triangle Universities Nuclear Laboratory has been designed. The detector package consists of two position sensitive gas avalanche counters, a gas proportionality energy loss section, and a residual energy scintillator. This setup allows both particle identification and focal plane reconstruction. In this paper we will detail the construction of each section along with their accompanying electronics and data acquisition. Effects of energy loss throughout the detector, ray tracing procedures, and resolution as a function of fill pressure and bias voltage are also investigated. A measurement of the 27Al(d,p) reaction is used to demonstrate detector performance and to illustrate a Bayesian method of energy calibration.

Position-sensitive proportional-counter system for use in the Enge split-pole spectrograph

Technical Report Greenwood, L R ; Stoltzfus, J C ; Katori, K ; ...

A variety of position-sensitive single-wire proportional counters with lengths up to 90 cm have been built and tested in the focal plane of the Enge split-pole spectrographs at the Argonne tandem accelerator and cyclotron. This report, which describes the counters, the associated electronics, and the data-handling procedures, is intended as an operating manual for general use of the system. Under ideal experimental conditions, the spatial resolution of the counters is about 1 to 1.5 mm (FWHM), dependent on the energy loss of the incident particle in the counter. The spatial response of the counters is linear to within 0.5% ofmore »« less

Characterization of a Focal Plane Camera Fittted to a Mattauch-Herzog Geometry Mass Spectrograph. 2. Use with an Inductively Coupled Plasma

Journal Article Barnes, James H ; Schilling, G ; Sperline, Roger ; ... - Analytical Chemistry

A novel charge-sensitive detector array, termed the focal plane camera (FPC), has been coupled to a Mattauch-Herzog mass spectrograph (MHMS) with an inductively coupled plasma ionization source. The FPC employs an array of gold Faraday cups, each with its own charge integrating circuit that allows the simultaneous detection of several m/z ratios. The ion-sampling interface of the MHMS has been redesigned to provide better heat transfer away from the sampler and skimmer cones and to reduce the negative effects of turbulent gas flows around the plasma. The instrument has produced limits of detection in the tens to hundreds of partsmore »« less

Spin-parities of subthreshold resonances in the ¹⁸F(p, α)¹⁵ reaction

Journal Article Portillo, F. ; Longland, R. ; Cooper, A. L. ; ... - Physical Review. C

The ¹⁸F(p,α)¹⁵O reaction is key to determining the ¹⁸F abundance in classical novae. However, the cross section for this reaction has large uncertainties at low energies largely caused by interference effects. In this work, we resolve a longstanding issue with unknown spin-parities of subthreshold states in ¹⁹Ne that reduces these uncertainties. The ²⁰Ne(³He,⁴He)¹⁹Ne neutron pick-up reaction was used to populate ¹⁹Ne excited states, focusing on the energy region of astrophysical interest (≈ 6 – 7 MeV). The experiment was performed at the Triangle Universities Nuclear Laboratory using the high resolution Enge split-pole magnetic spectrograph. Spins and parities were found for states in the astrophysical energy range. In particular, the state at 6.133 MeV (more »« less

Use of the gas-filled-magnet technique for particle identification at low energies

Technical Report Rehm, K. K. ; Jiang, C. L. ; Paul, M.

Reaction studies of interest to astrophysics with radioactive ion beams will be done mainly in inverse reaction kinematics, i.e., heavy particles bombarding a hydrogen target. The low energy of the outgoing heavy reaction products makes particle identification with respect to mass and nuclear charge a major challenge. For the planned {sup 18}F(p,{alpha}) experiment one expects five different types of particles in the outgoing channels: {sup 18}F and {sup 18}O (from elastic scattering of {sup 18}F and {sup 18}O on {sup 12}C), {sup 15}O and {sup 15}N (from the {sup 18}F and {sup 18}O induced (p,{alpha}) reactions) and {sup 12}C recoilsmore »« less
