Integration of the End Cap TEC+ of the CMS Silicon Strip Tracker

The silicon strip tracker of the CMS experiment has been completed and inserted into the CMS detector in late 2007. The largest sub-system of the tracker is its end cap system, comprising two large end caps (TEC) each containing 3200 silicon strip modules. To ease construction, the end caps feature a modular design: groups of about 20 silicon modules are placed on sub-assemblies called petals and these self-contained elements are then mounted into the TEC support structures. Each end cap consists of 144 petals, and the insertion of these petals into the end cap structure is referred to as TEC integration. The two end caps were integrated independently in Aachen (TEC+) and at CERN (TEC--). This note deals with the integration of TEC+, describing procedures for end cap integration and for quality control during testing of integrated sections of the end cap and presenting results from the testing

Limitations and Confusing Aspects of Diagnostic Testing for Neurologic Lyme Disease in the United States

In the United States, laboratories frequently offer multiple different assays for testing of cerebrospinal fluid (CSF) samples to provide laboratory support for the diagnosis of central nervous system Lyme disease (CNSLD). Often included among these diagnostic tests are the same enzyme immunoassays and immunoblots that are routinely used to detect the presence of antibodies to Borrelia burgdorferi in serum. However, performing these assays on CSF alone may yield positive results simply from passive diffusion of serum antibodies into the CSF. In addition, such tests are only U.S. Food and Drug Administration cleared and well validated for testing serum, not CSF. When performed using CSF, positive results from these assays do not establish the presence of intrathecal antibody production to B. burgdorferi and therefore should not be offered. The preferred test to detect intrathecal production of antibodies to B. burgdorferi is the antibody index assay, which corrects for passive diffusion of serum antibodies into CSF and requires testing of paired serum and CSF collected at approximately the same time. However, this assay also has limitations and should only be used to establish a diagnosis of CNSLD in conjunction with patient exposure history, clinical presentation, and other laboratory findings
