  1. Status of Electron ID Yoon 25 Apr. 2006 DONUT meeting

  2. Step2 Step1 Δθ＜40mrad Δr ＜100 mm Reject penetrating track Step3 Reject single track Step4 Δθ＜20mrad Δr ＜30 mm

  3. Criteria for Electron ID in ECC (1) Position difference Δr＜30 mm (2) Angle difference Δθ＜20 mrad (3) More than 2 segments tracks. Position difference Δ Angle differenceΔθ （＜νＥ＞～８０ＧｅＶ）

  4. Size:600x600μm From vertex to most downstream plate in ECC Criteria for Electron ID in ECC (1) Position difference Δr＜30 mm (2) Angle difference Δθ＜20mrad (3) More than 2 segments tracks. Position difference Δ Angle differenceΔθ （＜νＥ＞～８０ＧｅＶ）

  6. New Located Events Step4 / all 1ry trk (no trk id ) Mod 1 32/ 116 (41) Mod 2 15/ 128 (46) Mod 3 31/ 113 (28) Mod 4 17/ 73 (23) Mod 5 6/ 42 (14) Mod 7 40/ 154 (35) Mod 8 1/ 24 (12) --------------------- Total 142/ 650 (199) * Old Located Events – 53 Nu E CC

  7. Next Step Among tracks withnon-zero in step 4 (142 tracks) … Using 3D viewer, we will select the further candidate tracks of electrons after rejecting penetrated tracks and single tracks. Method: Comparing tracks with wider allowance of Δθ and Δr (0.02 rad, 100 mm) And then Manual check …
