A study in using MICROMEGAS to improve particle identification with the TAMU-MDM focal plane detector

Decay properties of 22Ne + α resonances and their impact on s-process nucleosynthesis

“…Elastically scattered target nuclei were detected in a series of resistive strip detectors in a barrel configuration (θ lab = 45 • -145 • ). Beamlike 26 Mg ( 25 Mg) recoils resulting from γ-ray (neutron) decay of 26 Mg excited states were unambiguously identified in the MDM focal plane using a combination of energy loss, total energy, and dispersive position signals from the upgraded Oxford detector [33,34], as demonstrated in Figure 1. The identification of 25,26 Mg recoils was confirmed by the coincident γ-ray transitions measured in the HPGe detectors.…”

Transfer reactions as an Indirect Method in Nuclear Astrophysics

“…At TAMU, this reaction was studied using peripheral neutron transfer in the mirror system. A 26 Mg beam at 12 MeV/n was used on a thin 13 C target to measure the elastic channel, 13 C( 26 Mg, 26 Mg) 13 C, as well as the single neutron transfer channel. The K500 superconducting cyclotron at TAMU was used to accelerate the Mg beam and the Multipole-Dipole-Multipole (MDM) [9] spectrometer with the Oxford focal plane detector [10,11] was used to separate the reaction products.…”

New constraints on the Al25(p,γ) reaction and its influence on the flux of cosmic γ rays from classical nova explosions

“…Here, an ≈ 0.1-pnA, 10-MeV/u beam of 25 Mg ions was used to bombard a 200-μg/cm 2 -thick target of polydeuterated ethylene (CD 2 ) n . Light charged particles were detected with the TIARA Si array [46], whereas 26 Mg recoils were identified at the focal plane of the MDM-2 magnetic spectrometer [47] using the upgraded Oxford ionization chamber [48,49]. In this setup, elastically scattered deuterons were detected just forward of 90 • , providing an absolute normalization of all differential cross sections, and protons resulting from the (d, p) reaction were detected over the angular range of θ lab = 137 • -169 • .…”
