Notes:

7. W1 consists of four layers with different number of turns. The number of turns of each layer is specified in Table

1. Add one insulation tape between the second and third layers.

8. W2 consists of two layers with triple-insulated wire. The leads of positive and negative fly lines are 3.5cm and

2.5cm, respectively.

9. W3 is space winding in one layer.
