| Different configuration of the Pixel Detector have been studied to determine which one would be the best to have a good resolution for pt and impact parameters for tracks. For the tracks we are interested in the pt range compatible with the one of tracks coming from a b-hadron decay (pt~ 3.5 GeV). | Different configuration of the Pixel Detector have been studied to determine which one would be the best to have a good resolution for pt and impact parameters for tracks.

| + | * TP- Technical Proposal: 4 Layers for the BP with pixel with the same resolution as the Run I in Phase I (13 um x 28 um); sensor: 100 um x 150 um, thickness T=0.3 mm ; innermost layer at 3 cm from the beampipe and the outermost layer 16.1 cm. | ||
| + | |||
| + | * TP with outer layer at 18.8 cm. | ||
| + | |||
| + | * TP but one layer (the 3rd one at radius=10.9 cm) removed. | ||
| + | |||
| + | * TP with better resolution (7um x 15 um) sensors in first layer. | ||
| + | |||
| + | * TP with better resolution (7um x 15 um) sensors in first layer (sensor thickness = 0.225 in the first Layer). [ If the pixel size is decrezed 75 um x 100 um, to have the same charge sharing between pixel that we have in the Run I, the thickness shoud be reduced] | ||
| + | |||
| + | * TP with better resolution (7um x 15 um) sensors in first layer, increasing material of the first layer [ the better resolution pixel has an area that is half compared to the Run I pixel. So in the same detector there will be a double number of pixel and an increase of the material, especially for the read-out]. | ||
| + | |||
| + | * TP with better resolution (7um x 15 um) sensors in all 4 layers, (pixel thickness =0.225 in all Layers). | ||
| + | |||
| + | * TP with better resolution (7um x 15 um) sensors in all 4 layers, increasing material in all layers. | ||
| + | |||

| + | * Strawman5 configuration is expalind in [[https:// | ||

| + | * Strawman5, with better resolution (7um x 15 um) sensors in 2 innermost ( and extension ) layers, Phase I resolution (13 um x 28 um) sensors in 2 layers. | ||
