X-ray crystallography, like mass spectroscopy and nuclear spectroscopy, is an extremely useful material characterization technique that is unfortunately hard for amateurs to perform. The physical o… ...

The Large Hadron Collider (LHC) gets a breath of fresh air as it collides beams of protons and oxygen ions for the very first time. Oxygen–oxygen and neon–neon collisions are also on the menu ...

In practice, such a collimator cannot be geometrically perfect, and it lacks sharp definition, so to speak. The solution to this difficulty is to divide up the cone of the collimator into several ...

Electro-Optics Technology Inc. EOT collaborates with customers to provide innovative, high quality, enabling laser components that represent the best value in terms of performance, reliability, and ...

This study presents the development of a new collimator design for a BNCT-SPECT system, tailored to overcome limitations that could be encountered in a BNCT clinical facility. BNCT-SPECT systems aim ...

The Position Readout and Survey system of the LHC collimators has to monitor in real time (RT), at a frequency close to 100 Hz, the position of the 555 synchronized axes with an accuracy of 20 mu m.

The conventional collimation system at the LHC is less efficient with ion beams, so some crystal collimators will be inserted for testing right before the oxygen–oxygen and neon–neon runs begin. ALICE ...

This study was undertaken to determine the effects of collimators on the accuracy of preoperative sestamibi parathyroid imaging of the neck. Methods: Forty-nine patients with primary ...

This is a crucial upgrade of the LHC collimation system to mitigate the problem of ion beam halos (halos of particles that stray from the beams' orbit). The conventional collimation system at the LHC ...

(Image: Joseph's family) It is with deep sorrow that we announce the passing of Joseph Tagg, an esteemed engineer, colleague and friend, who died on 10 June 2025 at the age of 43. Joseph was a ...
