1. EXISTING SITUATION AND INTRODUCTION

Figure 1 illustrates the existing layout in the area that is to be renovated. The area is highlighted

in Figure 2.

Figure 1: Existing layout of equipment it the area

2. REASON FOR THE CHANGE

The East Area renovation will cover the refurbishment of the East Hall with its beam lines and

infrastructure. A re-design of the beam lines is included to improve the magnet situation, the

radiation situation and maintainability in general. The performance of the new beam lines will

be improved in terms of maximum momentum and in choice of particle type. Considerable

energy savings will be possible due to a cycled powering mode of the magnets instead of a

steady state one. Therefore, several magnet families have to be re-designed to be in accordance

with the purposes of the project.

3. DETAILED DESCRIPTION

As part of the renovation of the East Zone, the F61 line will be completely renovated, this

includes the following activities:

1. Replacement of all magnets

2. Renovation of magnet interlock system (Switch to WIC system)

3. Renovation of the beam instrumentation

4. Replacement of beam stoppers

5. Renovation of the vacuum system

6. Replacement of mechanical supports

Vent PS

To dismantle the Q74 magnet (F61.QFO01), it is necessary to vent the corresponding PS

vacuum sector.

Figure 6: Location of vacuum separation

Change in separation between b.352 and b.157

It is planned to change the separation between b.352 and b.157. An airtight wall will replace

the concrete block wall. As long as the wall is not installed, a concrete block will always be

kept in place to ensure that no access is possible through this passage.
