7. Identification of digitized particle trajectories

Abstract

High-energy Physics Laboratories make increasing use of particle detectors which directly produce digital measurements of trajectories at very high rates. Data collected in vast amounts during experiments are then analysed by computer programs whose first task is the recognition of tracks and reconstruction of the interesting events. This paper discusses the applicability of various Pattern Recognition approaches. Examples are given of the problems and the practical achievements in this field.

9. Hardware processors for pattern recognition tasks in wire chamber data

Abstract

A method for the recognition of curved tracks and its implementation in digital hardware is presented. Similar hardware processors can be used for point-finding in multi-plane multi-wire chambers. A comparison is made of the execution speed of special purpose hardware processors and Fortran routines running on large scale general purpose computers. Polynomial evaluators which are mentioned can be of interest for event selection.

10. The application of multi-dimensional analysis techniques to the processing of event data from large spectrometers

Abstract

In order to be able to handle the expected event data-taking rates of the near future, techniques capable of rapid data reduction and analysis will be required. The conventional approach to track recognition and geometrical reconstruction would require unrealistically large amounts of computer time, even with the fastest computers available at present. In addition, future detector layouts that attempt to minimise construction cost and maximise data rates, might not be well suited to conventional track following and geometrical fitting techniques. In this paper, we shall consider the usefulness of multi-dimensional analysis techniques for fast data processing. Their application to some existing large spectrometers will be described, as well as the possible constraints imposed on the detectors and detector layouts of the future. In this, therefore, multi-dimensional analysis can be used to guide the hardware in a rather general way, rather than simply expecting the software to solve all problems imposed by the hardware often at great cost in computer time.

12. Point and track-finding processors for multiwire chambers

Abstract

The hardware processors described below are designed to be used in conjunction with multi-wire chambers. They have the characteristic of being based on computational methods in contrast to analogue procedures. In a sense, they are hardware implementations of computer programs. But, being specially designed for their purpose, they are free of the restrictions imposed by the architecture of the computer on which the equivalent program is to run. The parallelism inherent in the algorithms can thus be fully exploited. Combined with the use of fast access scratch-pad memories and the non-sequential nature of the control program, the parallelism accounts for the fact that these processors are expected to execute 2-3 orders of magnitude faster than the equivalent Fortran programs on a CDC 7600 or 6600. As a consequence, methods which are simple and straightforward, but which are impractical because they require an exorbitant amount of computer time can on the contrary be very attractive for hardware implementation. To find particle trajectories, for instance, a systematic search through all possible combinations of co-ordinates will take a prohibitively long time on a computer when the number of tracks and the number of points per track are larger than 3 or 4. But hardware implementation is perfectly feasible and very fast, as will be shown later.
