The Detector DCR
The Detector Concept Report (DCR) consists of two parts, one for the physics
and the other for ILC detectors. It has been prepared as the accompany document
of the ILC Accelerator Reference Design Report. The detector DCR describes ILC
detector designs, R&Ds on detector technologies and expected performances. The
overview of the Detector DCR and the plan for the final release are presented.Comment: 13 pages, 8 figures, to appear in the proceedings of the Internationa
Linear Collider Workshop LCWS2007, Hamburg, German
JLC Overview
JLC is an e+e- linear collider designed for experiments at Sqrt(s)=500 GeV
with a luminosity of up to about 2.5x10^{34}/cm^2/s. In this talk, after
describing the parameters of JLC accelerator and detector, the feasibilities of
JLC to study Higgs, Top, and SUSY physics are presented based on the ACFA
report.Comment: 20 pages, 28 figures. Presented at the 7th Accelerator and Particle
Physics Institute (APPI2002), Iwate, Japan, 13-16 Februrary, 2002. Full

ILD MC production for detector optimization
A large scale Monte Carlo production has been pursued since spring 2018 for
the ILD detector optimization studies based on physics benchmark processes. A
production system based on ILCDirac has been developed to produce samples in
timely manner. The system and its performance are presented.Comment: Talk presented at the International Workshop on Future Linear
Colliders (LCWS2018), Arlington, Texas, 22-26 October 2018. C18-10-2
A Handy Tool for History Keeping of Geant4 Tracks and its Application to Studies of Fundamental Limits on PFA Performance
It is widely recognized that good jet energy resolution is one of the most
important requirements to the detectors for the future linear collider
experiments. The Particle Flow Analysis (PFA) is currently under intense
studies as the most promising way to achieving the best attainable resolution.
In order to clarify the fundamental limits on the jet energy resolution with
the PFA, we have developed a set of C++ classes that facilitates history
keeping of particle tracks within the framework of Geant4. In this paper this
software tool is described and applied to a generic detector model so as to
identify fundamental limiting factors to the PFA performance.Comment: To be submitted to Computer Physics Communication
KEK GRID for ILC Experiments
The LCG GRID system is the indispensable infrastructure for large scale
computing required for ILC experiments. It had been used extensively for ILD
LOI studies and its use will be further increased in coming DBD studies.
Experiences during the LOI era and plan towards DBD study in KEK are presented.Comment: 4 pages, 2 figures, proceedings of the Internationa Linear Collider

Extraction Method of Fine Granular Performance from Scintillator Strip Electromagnetic Calorimeter
We describe an algorithm which has been developed to extract fine granularity
information from an electromagnetic calorimeter with strip-based readout. Such
a calorimeter, based on scintillator strips, is being developed to apply
particle flow reconstruction to future experiments in high energy physics.
Tests of this algorithm in full detector simulations, using strips of size 45 x
5 mm^2 show that the performance is close to that of a calorimeter with true 5
x 5 mm^2 readout granularity. The performance can be further improved by the
use of 10 x 10 mm^2 tile- shaped layers interspersed between strip layers.Comment: 11 pages, 10 figure
Simulation Study of FPCCD Vertex Detector
We are developing the vertex detector with a fine pixel CCD (FPCCD) for the
international linear collider (ILC), whose pixel size is
m. To evaluate the performance of the FPCCD vertex detector and
optimize its design, development of the software dedicated for the FPCCD is
necessary. We, therefore, started to develop the software for FPCCD. In this
article, the status of the study is reported.Comment: 5 pages, 4 figures, Proceedings of LCWS/ILC201
Irradiation test on FD-SOI Readout ASIC of Pair-monitor
We fabricated a readout ASIC with the fully depleted silicon-on-insulator
(FD-SOI) technology for the pair-monitor. The pair-monitor is a silicon pixel
device that measures the beam profile of the international linear collider. It
utilizes the directional distribution of a large number of electron-positron
pairs created by collision of bunches, and is required to tolerate radiation
dose of about a few Mrad/year. The irradiation might cause the buried oxide
layer of SOI to accumulate charges which interfere with intended functions. We
thus performed extensive irradiation tests on the prototype ASIC, and the
results are described in this paper.Comment: 4 pages, 3 figures, LCWS1
R&D Status and Plan for FPCCD VTX
Fine pixel CCD (FPCCD) is an option for the sensor used for the ILC vertex
detector to reduce the pixel occupancy due to the high background rate near the
interaction point. In this paper, we report on the R&D status of FPCCD sensors
and the R&D plan for the sensors and the cooling system.Comment: 4 pages, 3 figures, Proceedings of LCWS/ILC2010
R&D Status of FPCCD Vertex Detector for ILD
Fine pixel CCD (FPCCD) is one of the candidate sensor technologies for the
vertex detector used for experiments at the International Linear Collider
(ILC). A vertex detector system for the International Large Detector (ILD)
using FPCCD sensors has been designed. We report on the R&D status of FPCCD
sensors, as well as the vertex detector design for ILD.Comment: 5 pages, 3 figures, LCWS1
