Fast trigger logic with digitized time information

Fast Polynomial Segmentation of Digitized Curves

We propose a linear-time algorithm for curve segmentation which is based on constructive polynomial fitting. This work extends previous work on constructive fitting by taking the topological properties of a digitized curve into account. The algorithm uses uniform (or L∞) fitting and it works for segments of arbitrary thickness. We illustrate the algorithm with the segmentation of contours into ...

Fast detection of masses in digitized mammograms

A novel method for fast detection of regions of suspicion (ROS) that contain circumscribed lesions in mammograms is presented. The position and the size of ROS are first recognized with the aid of a Radial-Basis-Function neural network (RBFNN) by performing windowing analysis. Then a set of criteria is employed to these regions to make the final decision concerning the abnormal ones. Accelerate...

VFAT2 : A front-end system on chip providing fast trigger information, digitized data storage and formatting for the charge sensitive readout of multi-channel silicon and gas

The architecture, key design parameters and results for a highly integrated front-end readout system fabricated as a single ASIC are presented. The chip (VFAT2) comprises complex analog and digital functions traditionally designed as separate components. VFAT2 contains very low noise 128 channel front-end amplification with programmable internal calibration, intelligent “fast OR” trigger buildi...

Trigger logic of the ATLAS First Level Muon Trigger

We present the design of the first level muon trigger in the central toroid of the ATLAS experiment at the Large Hadron Collider (LHC). The trigger is based on fast, finely segmented gaseous detector, Resistive Plate Chambers (RPC), to unambigously identify the interaction bunch crossing and to provide a sharp threshold over a large interval of transverse momentum. We describe the logic scheme ...
