* Missing mass resolution simulation with CH2 target
* Effect of Ξ- and decayed particles from Ξ- on the energy loss correction of missing mass. --> Correction seems to be impossible.
* will start designing WC detectors, and frame of WC and TOF detectors.

* S-2S official web page was updated.
* S-2S Wiki:
* Edit can be done by only core members (Nagae, Gogami, Kanatsuki, Takenaka) so far.
* Acceptance map for generation points (x,y and z) around target region were shown as histograms.
* Momentum resolution with drift chambers (simulation)
* No wires: FWHM = 5.5 × 10-4
* W plate (0.1 μm) : FWHM = 5.7 × 10-4 (thought to be realistic case)
* W plate (1 μm): FWHM = 6.3 × 10-4 (comparable level to the case with fiber detector)
* W plate (10 μm): FWHM = 12 × 10-4
* About SDC2:
*If SDC2 is used with rotation of 90 degrees, x-position resolution is deteriorated (σx = 0.2 mm → 1.1 mm). --> Δp/p = 7.7 × 10-4 (This result is worse than that of our intuition. Need to be checked.)
* Required sizes for drift chambers:
* SDC1: 75 × 125 mm2
* SDC2: 95 × 240 mm2
* SDC3: 800 × 400 mm2
* SDC4: 920 × 550 mm2
* Detector lists
* Schedule for preparation
====竹中====
* Analyses of data of prototype WC detector, which were taken at ELPH
* x,y-position dependence were shown.
* Position dependences were smaller than those of Geant4 simulatin. --> will use the Geant4 simulation by himself with Kanatsuki-kun's support.
* Preparation for presentations in Atagawa and Hawai meeting.
* Rough overview will be prepared by next week.
====その他====
* Indian summer school in Prague, Czech Republic (9/3 - 9/7)
* Next S-2S regular meeting: TBD ( 9/16(火) 10:30- ? )
* Workshops at Atagawa (9/23-25) (9/25-27)
