TL;DR: In this article, the authors present a fast (30 μs) on-line trigger that selects, from 300 GeV/c π − interactions, events with three tracks of transverse momentum larger than 0.9 GeV / c.

TL;DR: In this article, a trigger aimed at selecting those nuclear interactions which contain a charm particle is described, which uses a fast emulator of the PDP-11 which calculates the impact parameter of the decaying charged tracks originating from the charm decay.

TL;DR: The drift chambers of the UA2 vertex detector were equipped with a FASTBUS-based, 100 MHz FADC system for the 1985 run of the CERN p p collider as mentioned in this paper.

TL;DR: The WA82 experiment at CERN as mentioned in this paper has collected data at the Ω facility at Cern for the study of charmed particles produced in hadronic interactions, and the required accuracy, 10 μm in the transverse plane, has been obtained with a telescope made of 23 silicon microstrip detectors, with pitch ranging from 10 to 50 μm.

TL;DR: In this article, the authors show that conventional techniques can be used for the design and manufacture of high-accuracy, cheap and densely packed charge digitizers, such as the CIAFB.
