Positrons at Jefferson Laboratory

We review the compelling case for establishing a capability to accelerate positrons at Jefferson Lab. The potential appplications range from the study of two-photon exchange and deeplyvirtual Compton scattering to exploiting the charge current weak interaction to probe the flavor structure of hadrons and nuclei. There are also fascinating ideas for using such a capability to discover new physic...

The Jefferson Lab 1 Kw Ir Fel

The Jefferson Lab (JLab) IR Demo Free Electron Laser (FEL) has completed commissioning and is initiating user service. The FEL — a high repetition rate, low extraction efficiency wiggler-driven optical cavity resonator — produces over 1 kW of tuneable light on intervals in a 3–6 μm wavelength range. It is driven by a 35–48 MeV, 5 mA superconducting RF (SRF) based energyrecovering continuous wav...

Active Learning in Physical Laboratory

In the contribution there is an importance of active learning presented, i.e. learning where students become active participants of the learning process. Active and collaborative learning can be realised in the physical laboratory. There are two possible methods of active learning in the physical laboratory presented: microcomputer-based laboratory and black-box method.
