The talk will present recent progress in the design and characterisation of CMOS
pixel sensors at LBNL. The talk will report results of lab tests, beam tests and
radiation hardness tests carried out at LBNL on a test structure with pixel of
various sizes.
We will also report the first preliminary results of a detailed characterisation of
backthinned CMOS pixel sensors and discuss future...

The Yale/Oregon effort to develop a CMOS vertex detector sensor with single bunch
crossing time stamping will be reviewed. The R&D program is first developing a large
pixel (50 um x 50 um) sensor, with a four deep memory for each pixel, and eventually
will move to fine pixels (10 um x 10um) by changing to a smaller feature size
semiconductor process.

Recent achievements with CMOS sensors of the MIMOSA series will be reported,
including test results of prototypes featuring radiation tolerant pixels operated at

Recent results are presented on the design and testing of silicon sensors for the ILC
vertex detector and of the associated readout electronics. The sensors discussed are
the Column Parallel Charge-Coupled Device (CPCCD) and the In-situ Storage Image
Sensor (ISIS), both of which have the potential to satisfy the requirements for
operation at the ILC. Progress with the development of the...

In our earlier investigations of radiation damage effects in a CCD based detector we
observed that some parameters of the radiation damage related processes were very
different from the common perception. For example, trapping time of electrons by
trapping centers created by irradiation was few orders of magnitude larger than it
was believed it should be. Last year we did additional...

A procedure of digitization of hits produced in the silicon tracking subdetectors of
the LC detector has been developed. The procedure has been employed to evaluate
point resolution of the vertex detector. In addition stand-alone pattern recognition
algorithm has been developed to search for tracks in the vertex detector.
Performance of the algorithm has been evaluated in the presence...

A vertex detector concept of the Linear Collider Flavor Identification (LCFI)
collaboration, which studies pixel detectors for heavy quark flavour identification,
has been implemented in simulations for c-quark tagging in scalar top studies. The
production and decay of scalar top quarks (stops) is particularly interesting for the
development of the vertex detector as only two c-quarks and...

The present mechanical design of the vertex detector for SiD will be described. The
design includes a 12.5 cm long central barrel with silicon pixels. Four disks with
silicon pixels and three additional disks, which could be based upon silicon pixels
or micro-strips, are located beyond each barrel end. Since sensor technologies are
rapidly evolving and final operating requirements are...

The Linear Collider Flavour Identification (LCFI) Collaboration is developing

Extremely low mass support structures will be required for the...

for these R&D studies was 50 cm diameter and 50 cm long and was operated with three
gas mixtures, Ar:CF4 3%, ArCH4 (P10) and Ar:Isobutane 5% in magnetic fields up to 2
tesla. A large-area, 38 cm diameter, copper Micromegas...

We conducted a series of beam tests of prototype TPCs at the KEK PS using GEMs or

spatial resolution as functions of drift distance, are presented with a special
emphasis upon comparison to the expectations from an analytical...

The MPGD readout TPC for the ILC will have to measure ~200 track points with a
resolution close to 100 microns for all drift distances. It may be difficult to meet
the resolution target with conventional MPGD readout techniques if ~2 mm wide pads
were used as is presently envisioned. Reducing the pad width to improve resolution
could add significantly to the detector cost and complexity....
