Selection of the dipoles for the installation in the second sector of the Large Hadron Collider.

The criteria for selecting the main dipoles of the Large Hadron Collider for the next sectors to be installed, characterized by a type L diode, is presented. The selection aims at minimizing the spread of the b3 in the next sector, by choosing dipoles featuring the largest b3 among the existing pool of available magnets. The constraints of having the same inner cable in the same sector, and enough magnets with a good geometry shape are also included in the selection. A list of 154 plus a reserve of 20 to be installed in the second sector is defined according to these criteria. The beneficial effect of this selection on the homogeneity of the sector is presented.
