High Power Window Tests on a 500 MHz Planar Waveguide Window for the CESR Upgrade (2007)
M. Pisharody, P. Barnes, E. Chojnacki, R. Durand, T. Hays, R. Kaplan, ...
We describe the low power and high power performance of planar waveguide windows designed and fabricated by Thomson Tubes and tested at LNS. These windows are intended for use in the phase III...

The design and application of iii-v multiquantum well optical modulators (1991)
Parry, G, Whitehead, M, Stevens, P, Rivers, A, Barnes, P, Atkinson, D, ...
The application of an electric field across a quantum well structure induces a shift in the exciton dominated absorption edge. This effect is exploited in a number of optoelectronic devices including...

The mode of action of azathioprine in the treatment of rheumatoid arthritis is not known. In this study we showed that azathioprine did not produce any consistent fall of NK cell numbers as detected...
AN ASSESSMENT OF THE GAPMETER LAB KIT (1977)
The Gapmeter Lab Kit series of flowmeters has been calibrated using air. Two of the flowmeters were also calibrated using argon and oxygen as the priming gases. Linear calibration graphs have been...
As a result of legislation in 1855, 1856 and 1862 that effectively enabled limited liability companies to be formed with minimum difficulty for the first time, there was an explosion of new...
