A simple pulsed slow positron beam based on a Penning-trap has been designed and is being constructed in Wuhan University. The cooled positrons from the trap with very low energy dispersion are dumped and chopped to pulses of a few tens of ns in width. Positron pulses are bunched by adjusting the potential of drift tube using an arbitrary wave generator, then accelerated to the target. Influences of the pulse width, the energy dispersion of positrons etc. on the time resolution of bunched positron pulse are simulated. The result shows that lower energy dispersion of positrons leads to much narrower positron pulses, indicating that a trap-based slow positron beam has a great advantage in developing a pulsed slow positron beam.

Layered Cuprates

We report systematic high-resolution angle-resolved photoemission spectroscopy (ARPES) on Bi 2 Sr 2 Ca n-1 Cu n O 2n+4 (n = 1-3) to study the electronic structure near the Fermi level (EF) and the low energy excitation. Comprehensive ARPES data on the sudden break in the energy dispersion near EF (kink) as a function of momentum, temperature, and number of CuO 2 layers indicate that the coupling of electrons with Q = (π,π) magnetic mode is dominant in the superconducting state for multi-layered cuprates.
