The concepts involved in the design and operation of a multi-wire proportional chamber are reviewed. The design and construction of two chambers for the SMC (Spin Muon Collaboration) muon polarimeter are described in some ...

A system to control and stabilize the output of visible laser diodes was developed and used to measure the velocity distribution of lithium atoms in a laser cooling experiment. Circuitry was designed and built for controlling ...

Spin polarized metastable deexcitation spectroscopy provides an important surface probe, in which a beam of thermal energy metastable noble gas atoms is deexcited at the target surface under study, releasing its energy ...

Spin-polarized electron energy-loss spectroscopy has been used to investigate the probing depth of low energy ($\sim$30 eV) electrons in metals. A beam of spin-polarized electrons is directed at the surface of the sample ...
