Independence of optical absorption on Auger ionization in single-walled carbon nanotubes revealed by ultrafast e-h photodoping

Auger-ionized free-carriers in a one-dimensional semiconductor are predicted to result in a strong band-gap renormalization. Isolated single-walled carbon nanotubes (SWCNT) under high-intensity laser irradiation exhibit strong nonlinear photoluminescence ( ...

Magnetic structure of the quasi-two-dimensional antiferromagnet NiPS3

Diane Virginie Marie Lançon

The magnetic structure of the quasi-two-dimensional antiferromagnet NiPS3 has been determined by magnetometry and a variety of neutron diffraction techniques. The experiments show that the samples must be carefully handled, as gluing influences the magneto ...

Hardening induced by radiation damage and helium in structural materials

Irradiation is known to lead to degradation of mechanical properties of materials. Structural materials for nuclear applications can be affected by helium produced by transmutations. The objectives of this work were: (a) to investigate the effects of He on ...

Performance and lifetime of micro-channel plate tubes for the TORCH detector

Christoph Frei

Timing Of internally Reflected CHerenkov photons (TORCH) is a time detector proposed for particle identification at low momentum. Charged particles passing through a plane of quartz produce Cherenkov light, some of which is trapped within the plane by tota ...

Helium ion irradiation induced swelling and hardening in commercial and experimental ODS steels

Manuel Alexandre Pouchon, Loïc Guillaume Fave

The radiation resistance of two promising ferritic ODS steels, PM2000 and 15CRA-3, is studied. More specifically, the effect of helium on these materials is studied by examining the swelling and hardening after He+ implantation to ∼1 dpa at 4000 appm/dpa. ...

Atmospheric amines and ammonia measured with a chemical ionization mass spectrometer (CIMS)

Athanasios Nenes, Satoshi Takahama, Giulia Ruggeri, Hairun Guo

We report measurements of ambient amines and ammonia with a fast response chemical ionization mass spectrometer (CIMS) in a southeastern US forest and a moderately polluted midwestern site during the summer. At the forest site, mostly C3-amines (from pptv ...
