We conducted a series of beam tests of prototype TPCs at the KEK PS using GEMs or
microMEGAS as a detection device. The prototypes were operated successfully under a
magnetic field of up to 1 tesla. Experimental results, such as pad response and
spatial resolution as functions of drift distance, are presented with a special
emphasis upon comparison to the expectations from an analytical calcul

This talk describes a calorimeter concept that will use cherenkov radiator plates to
partially replace the metal plates in a conventional ILC hadron calorimeter design.
The cherekov radiator will have fine segmentations and will be readout by SiPMs.
Energy and spatial information of the electromagnetic components in hadron showers
can be measured. Combined with information from thin plastic sc

We examine the resolving power of an e-gamma collider in the context of HWW vertices.
This has the advantage over an e+e- collider in being able to dissociate them from
any deviations in the ZHH vertex. We construct several dynamical variables which may
be used to constrain various possible form factors in the HWW vertex.

gamma gamma to ZZ and gamma gamma to WWWW at polarized and unpolarized photon

Doubly charged scalars, predicted in many models having exotic Higgs representations,
can in general have lepton-number violating (LFV) couplings. The basis of most
searches for this charged scalar has been to look for its direct production and its
subsequent decay to like-sign final state leptons. In this work we show that by using
an associated monoenergetic final state photon seen at a futu

A calorimeter energy calibration method has been developed for ILC detectors. The

Among the viable alternatives to the
Standard Higgs Mechanism is the recently proposed Little Higgs
models. The advantage here is that the model has an elementary
light neutral scalar particle without the hierarchy problem. The model
has two heavy charged gauge bosons W_H and one heavy neutral gauge
boson, Z_H, in addition to the standard W and Z. We have

It is very likely that due to the cost “optimization” the ILC will have only one
detector and no further energy upgrade. This scenario with a long run time at the
energy 2E<=500 GeV only strengthens the case of the photon collider. In any case, it
is very important to develop a design which allows the best possible parameters of
the photon collider. The gamma-gamma luminosity is determined

We have studied the performance of the CMS hadron calorimeter using the testbeam
facilities at CERN. Two wedges of brass-scintillator calorimeter are exposed to
negative and positive beams with momenta between 3 and 300 GeV/c. Light produced in
the scintillators were collected using wavelength shifting fibres and read out using
Hybrid photodiodes. Each of the wedges had 17 layers of scintilla

The access to the purest initial state is possible by use of two highly polarized
electrons. We give an up-to-date review of where we stand in this effort - including
its accessibility in the context of its basic compatibility with the beamline and
detector used for e+e- - initiated interactions.

In many SUSY models the first SUSY signal in the proposed International Linear
Collider is expected to come from the pair production of stau particles,
followed by its decay into tau lepton plus lightest neutralino assumed to be
the lightest supersymmetric particle. In our study a simple and robust method
of measuring the polarization of this tau in its 1-prong hadronic decay channel,has
been

The concept of virtual observatories has recently emerged to enable
astronomers to deal with the management, analysis, visualization and
mining of vast quantities of astronomical data. The task is difficult
because of the diversity of data obtained at different wavelengths and the
very different techniques used in the analysis. There is the need to
develop data formats, interoperabilit

A new scheme of read out electronics which will be used for MPPC new type of photon
sensor is under development in KEK. The aim and situation is reported. Both analog to
digital conversion data and timing information are relevant for this detector, thus
specail care are taken for them.
