Detailed Description

This class simulates the functionality of the anode LCT card. It is run by the MotherBoard and returns up to two AnodeLCTs. It can be run either in a test mode, where it is passed an array of wire times, or in normal mode where it determines the wire times from the wire digis.

This is the simulation for the Anode LCT Processor for the Level-1 Trigger. This processor consists of several stages:

Pulse extension of signals coming from wires.
Pretrigger for each key-wire.
Pattern detector if a pretrigger is found for the given key-wire.
Ghost Cancellation Logic (GCL).
Best track search and promotion.
Second best track search and promotion.

The inputs to the ALCT Processor are wire digis. The output is up to two ALCT digi words.
