**Introduction**

> During the 2005 shutdown, Booster 400 MeV Transfer Line injection will
> undergo a major modification. In general, the job is relatively
> straightforward: remove beam line components downstream of quadrupole
> Q13, remove orbump girder, with all its components on it except for
> the ion pumps, install new girder with new magnets and vacuum
> components and finally reinstall 400 MeV components at different
> configuration.
>
> There are two radiation areas in this section of the transfer line:
> one between Q15 and MH2-2 (\~120mrem/hr @ contact) and the other at
> DCSEP magnet/girder region (\~ 200 mrem/hr @ 1 foot). The picture
> below shows a sub set of the radiation survey data taken since last
> shutdown (Aug'04). The latest values are represented by the black
> line. These measurements were taken at 1 foot after some cooldown
> period.

> This document will describe in details the necessary steps to modify
> the injection line into booster.

> Through out this document, the following notation will be applied:

1.  BPM \-- beam position monitor

2.  Trim \-- corrector magnet

3.  MW \-- multi wire

4.  IP \-- ion pump

5.  QM \-- quadrupole magnet

6.  BM \-- bending magnet

7.  † \-- normal dose expected

8.  ‡ \-- high dose expected

> **General Procedure**
>
> Access Booster to survey area, assess job and do radiation survey. The
> radiation survey needs to be done one week prior start working.
>
> This work will be divided in two parts: Removal and Installation.
> After completion of Removal Jobs the radiation in the area should drop
> considerably.
