Water Cherenkov detector
Number of photoelectrons were:
57.4±0.5 (H6522×2)
39.7±0.4 (H11284×1)
Cap design for window test was done.
Simulation with Geant4 is in progress.
Effective speed of light in S-2S TOF detector:
1.57±0.01 m/s
→ Path length is effectively longer by 20%.

SDC2
Matching of ADC card with a connector of the chamber is confirmed.
Design is almost completed.
HV line of center part will be separated from others.
Magnetic field calculation for Q2 magnet with Opera-3D(TOSCA)
Comparison of a measured magnetic field (2500 A) with a TOSCA calculation with current of 2700 A.
--> Still the calculation is less than the measurement.
Found asymmetry in y-axis which might be caused by a platform of magnetic field measurement. → Need to be confirmed in further study with TOSCA.
Simulation for PRE-E05 experiment with SKSMinus
Background rate from K- beam decay:
10-3 [/K-]
(Dominant source is π+)
Background rate from reactions will be studied.
Schedule
Pre-meeting with E13 group: 2014/11/13 or 14 ? Next S-2S meeting: 2014/11/18 (Tue) 10:30- K1.8 beam time meeting: 2014/11/19 (Wed)IMPORTANT!!!
