[en] The nuclear physics at lower energies are subject to the production of protons, alpha particles and other light charged particles of lower energy at the exit channel. The detection and discrimination of these charged particles are important for the extraction of important physics from the experiment. The ADC-PSD spectrum measured using LiFSi hybrid detector configuration. The projection of the α band. The figure in the article shows a clear discrimination between α and protons, at lower energies. In the projected alpha spectrum, the alpha colonies from ¹⁰B(n, α) reactions corresponding to ground and excited states are well resolved. The set up provides 71 KeV energy resolution in FWHM units corresponding to 1.94 MeV alpha. The particle discrimination starts from 270 KeV for alpha and protons. As the detector meets the requirements of particle discrimination at lower energies, and achieves the energy resolution,it can be effectively used for detection and measuring of low energy charged particle with effective particle energy discrimination

[en] The measurement and analysis of neutron induced reactions ideally demands a δ−function neutron spectrum. Due to practical limitations in the production of δ− function neutrons, the quasi monoenergetic neutrons are being utilised for the measurement of point cross sections. The neutron spectrum from ⁷Li(p,n) at 21 MeV, achieved through unfolding the neutron response spectrum is illustrated in the article, along with the theoretical spectrum reported by Midhun et al. In the present measurement, it is identified that n₀ and n₁ groups are merged together and formed as a single gaussian due to the higher thickness of the target. Further the neutron groups corresponding to resonant breakup of ⁷Be from 7/2⁻ and 5/2⁻ states, the direct groups are identified with acceptable resolution. The present measurement validates the n₀, n₁ and the three-body breakup contributions of ⁷Li(p,n) neutron spectrum at 21 MeV

[en] The low energy nuclear reactions producing extreme low energy neutrons in the exit channel have a renewed interest due to their larger involvement in nuclear astrophysics and radiation dosimetry. Most of the reactions in this range belongs to direct reactions only and those neutrons are not accompanied by any γs. The unfolded spectrum of neutrons, compared with the theoretical spectrum. This shows that the spectrum is similar and the low energy with a starting point of 100 keV is well measured. The experiment shows that this method clearly discriminates low energy neutrons and γs and can be effectively utilized for the situations of nuclear astrophysics where low energy neutrons in the exit channel are present

[en] Research in low-energy nuclear physics demands low-energy charged particle beams with lower energy spread and lower emittance. The production of high current beams with lower emittance is an open problem, till now in the field of accelerator physics. Understanding the requirements of nuclear astrophysics and other low energy applications, a novel ion source design has been developed to meet the demands of high current with lower energy spread and emittance. This has been achieved through a hybrid ion source design having a combined ECR Glow discharge mode of operation. The ECR modes have been generated with a TEM01 class rectangular waveguide design. Further the plasma is confined into a small volume by the externally configured magnetic field. The emittance blow up has been reduced by applying the background gas injection in perpendicular to the beam direction. The details are discussed herein
