Abstract

The Online Silicon Vertex Tracker (SVT) is the new trigger processor dedicated to the 2-D reconstruction of charged particle trajectories at the Level 2 of the CDF trigger. The SVT links the digitized pulse heights found within the Silicon Vertex detector to the tracks reconstructed in the Central Outer Tracker by the Level 1 Fast Track finder. Preliminary tests of the system took place during the October 2000 commissioning run of the Tevatron Collider. During the April-October 2001 data taking SVT was fully assembled and it was possible to obtain clearer and more important results on the performance of the system. In this paper we review the tracking algorithms implemented in the SVT and we report on the performance achieved during the early phase of run II.

CDF在线硅顶点跟踪器的性能

在线硅顶点跟踪器(SVT)是一种新的触发处理器，专门用于在CDF触发器的第2层重建带电粒子轨迹。SVT将硅顶点探测器内发现的数字化脉冲高度与1级快速追踪器在中央外部追踪器中重建的轨迹连接起来。该系统的初步测试在Tevatron对撞机2000年10月调试运行期间进行。在2001年4月至10月期间，采用SVT的数据得到了完整的汇编，并且可以获得关于系统性能的更清晰和更重要的结果。在本文中，我们回顾了在SVT中实现的跟踪算法，并报告了在运行II的早期阶段所取得的性能。
