The Parts needed for the modification.

Graeme Barlow - TE-MSC-CMI 7

The Clamp (for thermal contact and location).

Graeme Barlow - TE-MSC-CMI 8

The Latches (for quick and easy opening, closing).

Graeme Barlow - TE-MSC-CMI 9

The Hinge & Braids (for opening the shield and for thermal conductivity). Graeme Barlow - TE-MSC-CMI 10

How many do we need to modify?

• 8 per day.

• 1695 for LS1 + 100 spares.

• 130 in stock now.
