Abstract: The instability of the sheet electron beam (SEB) is an essential factor for limiting the power of the SEB traveling wave tube (TWT). To solve this issue, this article proposes a method to ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

Physicists at the University of Oxford have contributed to a new study which has found that iron-rich asteroids can tolerate ...

This important study combines optogenetic manipulations and wide-field imaging to show that the retrosplenial cortex controls behavioral responses to whisker deflection in a context-dependent manner.

The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples. By ...

The V-660 is a double-beam spectrophotometer utilizing a double monochromator and a photomultiplier tube detector. The use of a double monochromator provides high resolution with extremely low stray ...
