'Cryo-illustrator' helps to open the door to physics in Japan
The World Year of Physics - 2005 - marks the centenary of Albert Einstein's annus mirabilis, when he published his three seminal papers on Brownian motion, the photoelectric effect and the special theory of relativity. In the image shown here, Tom Haruyama of KEK is assisting Einstein in opening the door he unlocked with these discoveries.
The illustration was adopted by the Japan Physics Society as the promotional poster for a seminar held in Tokyo last summer in anticipation of the World Year of Physics.
Haruyama is a specialist in cryogenics for the high-energy physics experiments at KEK. He is also well known as Asian editor of the international journal, Cryogenics, published by Elsevier, and has been the secretary of the International Cryogenic Engineering Committee for many years.
At the same time, Haruyama is able to create this kind of illustration to enhance the popularity of physics with young people in Japan, without compromising his own work in cryogenic research.

New Products
Creative Group has released a new high-vacuum manual in-line valve, which operates down to 10-8 mbar. The unit has a particularly high molecular conductance for this type of valve, and its stainless-steel construction makes it ideal for high-temperature applications. It is small, lightweight and easily serviced, and can accommodate any combination of fittings.

Bede has announced BedeMetrix X-ray metrology tools for enhanced spot measuring of semiconductor wafers from 50 to 300 mm. This new capability allows measurement of sub-100 μm test pads in chips and scribe lines on processed wafers, and provides automated characterization of fabrication processes. The BedeMetrix-L tool measures fundamental properties and structures of materials, including epitaxial and non-epitaxial layers.

Glassman has developed low-profile 300 W regulated HV DC power supplies covering the range 1-60 kV. The FX series of supplies deliver high power density in a compact, lightweight unit 4.45 cm (1.75 inch) high in a standard 48.3 cm (19 inch) panel. Air-insulated, the units feature tight voltage regulation of better than 0.005% and current regulation better than 0.05%.

Montena emc, which offers high-voltage and high-frequency products such as pulse generators, coupling networks, sensors and antennas, has recently produced a new pulse generator with a peak voltage of 320 kV, a rise time of 5 ns and a half-value time of 100 ns. The device is very compact, thanks to the choice of insulation (high-pressure nitrogen plus sulphur hexafluoride), which enables the fast rise time.
