• Selecting each region’s layers or disks region 1 st Layer 2 nd Layer 3 rd Layer 4 th Layer 1 O O 2 O O O 3 O O 4 O 5 1 st Disk 2 nd Disk O O 3 rd Disk 4, 5, 6 Disk O O OOO • To cover forward region(region 5), use pixel combination Disk 3 to 6 D 3456

• Individual disk’s efficiency (Delta R < 0. 1) • There are efficiency drops in forward region. • Because ECAL’s resolution is low in forward region.

• Individual disk’s efficiency (Delta R < 0. 2)

• How to draw signal windows plot? Bpix_l 1_dphi (et 40) Mean + 3 sigma Mean - 3 sigma

• It is hard to draw signal window plot by using only forward regions points. • So I changed Eta cut range from 2. 5~2. 8 to 2. 4~2. 8. Eta 2. 5~2. 8 disk 4

• Compared to earlier slide, the fluctuation has decreased Eta 2. 4~2. 8 disk 4

Et 40 Et 41 Et 42 Et 43 • Some Et has relatively low events and it is the cause of high fluctuation

• Compressing two points Et 40+41 Et 41 • Abnormal points have relatively low entries. • By compressed two Et points, statistical fluctuation can be reduced.

Et 40+41 Et 40 + Et 41 • We can confirm that the fluctuation has been reduced compared to the first one.

• The points listed by 1 Ge. V are highly distributed. So it is difficult to draw plot

Compress 1 Ge. V->2 Ge. V Fluctuations are decreased and it is possible to draw ROI plot

• 2 Ge. V compressed points. but still has difficulty to draw plot

• If compressed by 2 Ge. V points still have high fluctuation, compress more wide union

• same compression task was done on EM_Pixel signal windows combination. • Types of EM_Pixel matching combination table. EM_D 3 D 4 EM_D 3 D 5 EM_D 3 D 6 EM_D 4 D 5 EM_D 4 D 6 EM_D 5 D 6 EM : ECAL D 3 : third disk D 4 : fourth disk D 5 : fifth disk D 6 : sixth disk

• If disk combination contains outer disks(disk 6), fluctuation is especially intensified.

• same compression task was applied on Pixel_Pix. El signal windows combination. • Types of Pixel_Pixel matching combination table.

• efficiency plot(under 2. 8) • Further plots were obtained including area between the Eta region 2. 5 to 2. 8. • Added plot shows around 0. 8 efficiency

• summary • Extend the study region 2. 5 to 2. 8 • By compressing energy intervals, drawing signal windows plot is become possible • If use a better resolution trigger, better efficiency will be made
