CS Distortion Kazuyama Yoshioka
Scanning Samples • Realistic CS film x 10 • 2nd refresh from ’06 July • (include Aug. run TTCS) • Some are installed to wall • Exposed 10 GeV π • Exposed & Developed in CERN in ’06 Sep.
Scanning Condition • Scanning Machine • UTS stage1 and stage2 • Angle acceptance : ±400mrad • PH cut : 7 • Scan room condition • Temp. 25℃ Humi. 40~45% • Emulsion thickness • 43.5~47.5μm (by manual)
Scanning Area y <Scan Area> 12mm x 9mm = 108 mm2 <Scan Area center> (x,y) = (60mm,50mm) 9mm 12mm x (0,0)
Base Track parameter • Angle Acceptance • Angle Difference< 100mrad • |(micro track angle) – (base track angle)|<100mrad • PH cut • PH Sum. > 20 • Sum. of 2 surface of 1 film.
Summary • Global Distortion • No Big Global Distortion • Over 10mrad … 3film • Local Distortion • Some point have big distortion (50mrad~) • 1 is scar • Future • SUTS 大面積… + Other Sample…
