The LHC employs the largest and most advanced cleaning system ever built for a particle accelerator. Fig. 1. An illustration of multi-stage cleaning in the transverse beam planes. Primary collimators ...

Abstract: Optical collimators are very important components in the construction of practical fiber network. But unfortunately, the problem of low-efficiency alignment is always a bottleneck of optical ...

No other telescope design offers the combination of features and portability as a Schmidt-Cassegrain telescope (SCT). You may not consider it the best for any one application, but it does everything ...

Objectives Our previous study demonstrated that CdTe detector based SPECT system with 4 Pixel Matched Collimator (4PMC), of which the hole size is matched to four (2x2) detector pixels, can provide ...
