# WBS 1.1 - Maintenance, Operations and Upgrade Estimate

# Introduction

This document contains a crude estimate of the Maintenance and
Operations(M&O) costs associated with WBS 1.1. Only M&O personnel costs
are estimated. It is assumed that M&O materials costs are covered by the
CERN estimates. The current LHC schedule is assumed. Upgrade costs are
also (very roughly(estimated under the assumptions given below. The
upgrade costs do not reflect the possibility to achieve luminosity
greater than 10^34^ and the considerable R&D that would be required for
tracking systems in such an eventuality.

# WBS 1.1.1 Pixel System

Part of the pixel system is delivered, installed and commissioned in
FY04 and part in FY05. I assume both mechanical and electrical
engineering labor will be required to maintain and operate the system
after commissioning is complete. One FTE technician will be resident at
CERN, augmented in FY04 and FY05 by 0.5 FTE traveling to CERN. It is
assumed that 0.75 FTE technician resident in the US will be needed to
support the CERN activity.

A major upgrade(replacement of the B-layer(s)) is assumed to occur with
installation in FY07-FY08. Costs are crudely scaled from the current US
contribution.

# WBS 1.1.2 Silicon Strip System

The US completes its deliverables by the end of FY03, although part of
the system will be completed earlier. Electrical engineering labor is
required after completion of the US deliverables. In this case we also
assume 1.0 FTE technician resident at CERN supported by 0.75 technician
in the US.

We assume two types of upgrades. First, a minor upgrade to provide spare
modules using 0.25 micron(or non-Temic) electronics starting about FY07.
Second, a major upgrade replacing the TRT with silicon in about FY10.

# WBS 1.1.3 ReadOut Drivers

Fabrication of the RODs is completed by the end of FY02. Engineering
labor is required for maintenance oversight. We have assumed again a
resident technician at CERN backed up by a part-time technician in the
US.

We assume two types of upgrades. First, one associated with replacement
of the pixel B-layer(s). Second, one associated with the addition of
silicon, replacement of the TRT.

The associated costs are summarized in Table 1.
