The following paper displays a summary of illustrative presentation of
electron beam welding. This presentation is a part of Days of
Science, taking place regularly in ISI Brno, usually at the beginning
of November. The visitors may see…
When some devices (e.g. vacuum or cryogenics) are manufactured, the need to
weld thin-walled parts is often met. Application of electron beam for this
purpose may bring, compared with micro-plasma or laser) some valuable advantages
balancing its higher…
This coaxial (one conductor) feedthrough is suitable for transferring DC or
AC signals (including RF) into vacuum. It is vacuum-tight sealed into ISO-KF
16 flange, including O-ring support. On air-side is designed for type N
receptacle, on vacuum-side for…
Single-pin vacuum glass-sealing feedthrough. The feedthrough can be
electron-beam welded, e.g. into custom flange. Its operational temperature range
is –196°C to +400°C. It can be used for UHV.
We deposit X-ray molybdenum/silicon multilayer system, which can be used in
the range from about 12 – 30 nm. Peak reflectance values are approaching 70%
for normal incidence.
At very short X-ray wavelengths (wavelengths below about 4 nm)
efficient…
To evaluate the impact resistance of thin hard nanocomposite, multilayer and
monolayer coatings in dynamic loading wear applications an impact test has been
used. An impact testing of the coatings was proposed by Knotek et al in the
1990s. During testing…
