A MICROMEGAS detection amplifier has been incorporated into the design of the TAMU MDM focal plane detector with the purpose of improving the energy resolution and thus, the particle identification. Beam tests showed a factor of 2 improvement over the original design, from 10-12% to 4-6%, for ions with A<40 at E/A around 10-20 MeV..

A gridded ionization chamber used as a focal plane detector at the back of the TAMU-MDM spectrometer was modified to use MicroMegas technology for the purpose of improving energy resolution and particle identification. The upgraded system was tested in experimental conditions with several heavy-ion beams at 12 MeV/u and found to achieve resolutions between 3.2% and 4.8%. [...]

AstroBox2 – Detector for low-energy β -delayed particle detection
/ Saastamoinen, A (Texas A-M, Cyclotron Inst.) ; Pollacco, E ; Roeder, B T (Texas A-M, Cyclotron Inst.) ; Spiridon, A (Texas A-M, Cyclotron Inst.) ; Daq, M (Texas A-M, Cyclotron Inst.) ; Trache, L (Bucharest, IFIN-HH) ; Pascovici, G (Bucharest, IFIN-HH) ; De Oliveira, R (CERN) ; Rodrigues, M R D (Sao Paulo U.) ; Tribble, R E (Texas A-M, Cyclotron Inst.)
Efficient suppression of β-background is essential for studies of low-energy β-delayed charged particle decays of astrophysical interest. A promising method for such studies has been a micro pattern gas amplifier detector where the sample is implanted into the gas volume and the decays that follow are observed with high gain and signal to noise ratio.

The nuclear structure of the 31Mg nucleus has been studied with the singleneutron knockout reaction. We report on the preliminary results of an experiment performed with the EXOGAM array coupled, for the first time, to the SPEG spectrometer at GANIL.We present a provisional result for the inclusive single-neutron knockout cross section of σinc= 90(5) mb.
